Thanks for all the advice on this. Good to have someone else looking over my shoulder making sure to at least warn me when I'm doing something I shouldn't. Yes, we're just using these as transfer pumps. One for each direction since they all seem to have a check valve built in, the only reversible ones I can find are pretty expensive. 14ga seems overkill for 5A. I use 16ga for almost everything. Will take a closer look at the ABS wires for sure, I like the idea of just using them for power and then grounding the other terminal of the pumps. Will probably see what other wires are running back there we're no longer using too. On the topic of wiring, any suggestions on a relay/fuse good for 80+ amps? Want to put both the pusher fans on the secondary fan circuit. Figure I'll switch the big relay I add with the stock wiring/relay. Those fans pull almost 30A each (over 30A when submerged in water apparently). Planning on putting both the puller fans on the primary fan circuit, they are small and don't draw as much so I should be good there. Currently have one of each on each circuit on 30A fuses.

I've been looking at the rally Leones and their brush guards and I was thinking something inspired by that. Something that mounts to the bumper and wraps around the side to cover the running lights. I'm buying a spare bumper from my parts guy so I don't have to modify my factory bumper. I plan on using industrial rubber vibration dampeners (originally designed to be placed between heavy machinery and a concrete pad to absorb vibrations). Hopefully these will act as a bushing to absorb impact. Otherwise I'd have to figure out some sort of suspension system for it. The rubber dampeners seemed to be the simplest solution. Otherwise I could make the mount out of aluminum tubing and bolt that to the chrome moly guard. The aluminum would act as a sacrificial absorber.

I believe not all SPFI cars here in the US came with an O2 sensor. California has more strict emissions regulations than the rest of the nation. The California cars got O2 sensors, the cars sold in all other states do not have O2 sensors. I believe. Regardless, not all SPFI cars have O2 sensors from factory. I have found it interesting that despite my car originally being sold in California, it doesn't have California-spec emissions equipment. It has the national standard emissions equipment. I believe the national standard is just an EGR setup and a charcoal canister. No O2 sensor and no EGR temp sensor.

In case you hadn't noticed we have a lot more options for vehicle modifications than Australia. These pumps are 255lph. Assuming this extra tank is 10 gallons that would take about nine minutes. Could have it going before you even start filling the main tank. Worst case you fill up the main tank, pull off to the side for ten minutes, then go back to the pump. Guess I'll find out. I think this will be the simplest way. One hose connecting the tops of the tanks for venting. One hose connecting the bottom of the secondary tank going down through one of the access panels and down to the bottom of the main tank. Have two fuel pumps side by side teed into that bottom hose one pointing each direction. One of those pumps could run the engine in a pinch. Definitely looking forward to the magically increased range.

Yeah righto. That’s against our Australian Design Rules (ADRs) over here. Can’t pump fuel between tanks when refilling. Not saying it isn’t done, just that if you’re found out or cause a fire somehow you’ll be raked over the coals for it. And a Fawcett pump would be bloody slow - about 2L per minute transfer rate. Would be better off plumbing in a fill tube between the main tank and auxiliary tank with a one way valve towards the aux tank. There would need to be a vent line to the filler neck to help with the transfer. Or just have a secondary fill pipe off the filler neck to the aux tank so it fills after the main tank is full. Many ways to do it without over complicating things. Our Pajero (Shogun/Montero) sports a dual filler neck behind the filler cap so we can choose to fill the main tank or the auxiliary tank. This secondary filler pipe follows the main tank until it needs to head to the aux tank. Its pretty awesome the first few times being empty on the fuel gauge, then hitting the aux pump switch and watching (from time to time) the main tank gauge go from empty to full without pulling over

"One for each direction" I remember him saying he doesn't want to have to separately fill the aux tank. He'd like to flip a switch while filling the main tank to transfer it up to the aux tank. And then activate the second pump to transfer it in the other direction when needed.

B and I worked on the secondary fuel tank for the Impreza. I pressure tested it and flushed it out, seems like it doesn't have any leaks even at 30psi. I got the mounting flaps carved up so it fits and matched up the bumper mount holes. We had to do a little more hammering in the spare tire well. We came up with a plan on how we want to mount the fuel pumps and run the hoses. I need to get another pump, some hoses and fittings. Going to try to get wire connectors for the ABS wires so we can use those for the fuel pumps since they're already running front to back and will never be used for ABS again. B replaced the cabin air filter and cleaned out the airbox and blower fan, they were all loaded with debris. He also traced the brake lines under the hood and we came up with a plan on eliminating the ABS module and plumbing the left/right steering brake from the black Outback.

I added the charcoal canister between the gas tank and vapor intake on the 2.2, plumbing the vacuum valve per Bushytail’s advice. Viola, all is well. No more excessive tank pressure, no more bucking. An aside to the main topic: The shift mechanism on the old 4mt was fixed with tapping threads clean through the sleeve, and shift rod. Really is the ‘gold standard’ to fix this. For anyone still using the four speed. I sure took the long way around to get this fixed. Just couldn’t let go of the fact that the 2.2 ran fine with no canister in GL wagon. But many thanks to all here who helped me to get this Brat running right!

I have not seen anything officially saying one way or the other. But I would also bet interference. Even the 2.2 went interference in '97ish. That said, I see the FSM has a specific note to use caution installing the timing belt on a 2.5, as incorrect timing could cause piston to valve contact, and there is no such note in the 3.0 timing chain section.... I don't think I've seen or known of one break a chain. I've heard timing chain noise several times before due to damaged/worn guides and/or tensioners. Not that it isn't possible, but I'd be highly skeptical that it just broke without making a bunch of noise. What Cam sensor code? P0340 is for cam sensor circuit, indicating a wiring issue or failed sensor, P0341 indicates good signal but out of time. I've had engines attempting to start with bad sensor data sound strange while cranking. If it broke on the highway, the valves are already bent. It'll turn over nicely now. Before you touch those cover bolts, definitely do a compression test. If it fails that, I would drop the exhaust and look up the ports at the valves you can see (IIRC the front valves are hard to see through the single exhaust ports), and then crank it again to see if you can hear the compression blowing out the exhaust. If you have cylinders with no compression, but the offending valve cover and check to see if the buckets move freely and smoothly. While a stuck valve won't prevent a bucket from moving all the way out, there won't be any spring pressure on it. I believe you can see the bank 2 chain through the oil filler cap. Drop the oil into a clean pan and look for debris. Cut open the filter for the same. I would expect to see considerable metal in the oil if the chain has been failing. Maybe even drop the lower pan and look for bigger pieces of debris. I have an 01 H6 with no compression on cylinder 3. It all blows out the exhaust. I removed the valve cover and can move the valve buckets/springs freely with a prybar, resistance and movement feels identical on all 6 exhaust valves on that side (I believe if the valve wasn't closing all the way, the spring/bucket would not return all the way). It will still run, just super rough. I believe it to be a burned valve. And I will almost certainly swap in a used engine before I bother pulling everything apart enough to replace a valve. I have a couple known good high mileage engines. Or maybe try to get a JDM, although those are a lot less common/cheap than they used to be.

Pre-holiday update - went a little further with what I'm jokingly calling the subsubframeframe. I'm building up a small weld-in subframe/frame extension to locate and mount the impreza sheet metal number to. Fairly straightforward for the most part - to keep the parts somewhat simple I've had to clearance cut parts of the tubing to be able to maintain the ability to construct it out of straight tubes and right angles. Bends may be a slightly more robust approach with less material, but my fixturing capabilites are somewhat limited. Sometimes I think I'd give a kingdom for a good welding fixture table, but then again my brain works pretty well designing and fabricating this way so for now I'll use what I've got. This assembly looks to me like it will end up fairly robust. A couple more brace pieces to guard against torque / shearing are in process, and all open ends and channels I've cut are all going to get boxed in prior to final assembly and welding. I'll also be adding a few more pieces on the top to both provide more footprint for welding to the truck and to center everything between the original frame rails. I gotta go dig out my box of fasteners from the disassembly process and see if I still have the bolts from the impreza suspension and subframe, because next up is getting some threads welded in. I think I labeled everything but things got hectic in the last few days before its removal so I'm going to have to see what's still around.

Thats nuts Jeszek! I miss my wagons! -Justin
