Where is the valve you are talking about?

Fubared has been better than spewing trails of gas all over town, and cheaper. Whatever it is/was, when I blew, it was clogged at first and now I can blow into the tank. No trails, no smells.

For now, I took the easy route. Removed the gas cap. Attached a vacuum hose to where the return enters the engine bay, and blew. Exactly as expected, could hear and feel bubbling going on in the tank. Check. Removed and attached said hose to the vent port entering the engine bay. And blew. Exactly as expected. Nada. Blew harder, boom, little bit of air seeped through to the tank. Blew more and more and more, eventually I could blow air through considerably, but still some restriction. Drove it home, no gas smell. No self purging out the return line going on. I think the vent is still a bit clogged, but way better than before. So for now it stays, I think I got bigger fish to fry now. Might open a post on head gasket symptoms/replacement. Been acting up a bit lately, not to mention they've probably been leaking for the last fifteen years. Thanks again GD and Naked Buell. Will update post if I run across any more fuel concerns.

Never looked inside the tank... never looked inside ANY gas tank... Copy that, thx GD.

Aw man.... so... yesterday I installed the two-port fuel filter under the hood and removed the unnecessary hoses... Same thing! Still have pressure buildup in the fuel tank. And now it is blowing out the return. lol. Anyone got any great ideas? Would this be a clogged vent line?

Damn. That's what I figured via the fsm. Live n learn, live and learn. I did pickup a two port fuel filter, so I'll go that route soon. Thx, GD.

Alright... so... that didn't work out too well for me. Today I got home and smelled a lot of gas after exiting the vehicle. With my arms full, I walked past the rear and noticed a long path of gas on the road... dangit. After relieving my arms, I went back out and popped the hood only to find gasoline dribbling (at not a very slow pace) out of the silver air filter that I installed the other day. I then ran over to the gas cap and purged the system, releasing a bunch (if not more than before) of built up pressure. And the dripping gas stopped under the hood. So, it seems that that line is connected to a low spot in the tank, otherwise, it wouldn't have pushed gas up and out. Next, I moved crossed (uncrossed) the lines, attaching the air filter to the line that comes through the firewall directly under the supply line and I routed the top of the fuel filter to where the air filter was located (to the left of the brake booster). I guess we'll watch it and see what happens. Not too sure how optimistic I am, as this is pretty much the same setup I had before, only with the extra parts removed... though now there is no return directly at the carb. Wish me luck.

Whoops, double post.

Hey did ya happen to figure this out? Or anybody else have the answer? Currently in the process of fabricating a new 'harness' and need to know which terminal is which. Thx.

Great, thanks again.

So... changed from a Nippon Denso to a Hitachi distributor, but the reman Hitachi doesn't include the wiring from the coil. I guess they're assuming you just stick with one or the other. The Nippon Denso comes with new wiring included. Does anyone have pics or know which terminal on the Hitachi disty go to the yellow and which goes to the black/white wire? I know the coil side, but I see no marks on the Hitachi. Thx.

...no f**king good...

Now that I think about it, I saw an ea82 in the junkyard this weekend, still.had the engine, not sure about the oil pump as I wasn't looking for that, but the lot was Nisqually Auto Wrecking, 360-456-6222

I recently bought one from Renton Subaru (dealer) here in washington. But that was for an EA81. I would think EA82's would be easier. Maybe give them a call. Good luck.

If it was mine, I'd probably just RTV a ring inside there, let it dry, and be good to go the next morning.

I just checked mine, but it's a 86 GL, EA81. My cap has a thick rubber gasket inside, and its definitely tight. Perhaps you're missing the gasket?

Copy that. Should be good now then. So, I understand the supply, return, etc. But what I'm trying to say is the pic I shared above, the pic from the FSM, (which I've highlighted to match the coloring of my original routing), they are calling the green lines the return, which would be the line you just told me to leave open. And they are calling the yellow lines the 'evaporation tube' (item 14, forgot to highlight that), which we just routed the return to. Evaporation sounds like vent to me, which would mean that now we both have the vent and the return crossed. No? I'm not tryin to mess with ya, just trying to understand, so please don't take it the wrong way. Totally appreciate your help. Hey, if it works, it works.

Sounds good I can handle that. It does look like the book is calling the green the return though, whereas your saying it's the yellow. That would make the green the vent, I can move the filter to there.

Damn. $100 bucks. I bet this is a $6 part somewhere, somehow. Been considering a self-repair as well. What's inside, a rubber diaphragm attached to the lever, a possible spring? Shouldn't be too tough. Can't send it in. I would, but unfortunately this is my commuter at the moment (and for the foreseeable future), I kinda need that lever in the right place until I get a replacement... Try http://www.philbingroup.com/, I haven't used them yet personally, but I plan to. They have a great reputation here on the boards, from what I've seen. And when I called about getting axles rebuilt, the guy was super friendly and knew exactly what I needed. (They just didn't have it at the time.) Best of luck!

Yup, no canister anymore. Naked Buell, thanks for takin the time to help me sort this out. It's been running a little sporadic lately, like a random fuel starvation or small vacuum leak. I did discover that the vacuum advance is shot, allowing air through the diaphragm, so that could be the issue I started with, got that plugged for now, on the engine side. I'm not sure if the vacuum advance ever worked though. I guess we'll get there one step at a time. Your input is appreciated. I routed the top of the Filter to the green line F, as shown in the pic. Leave which one open? This seems contradictory... Delete Blue? Blue is my main supply... It is currently routed direct form carb to fuel inlet (via the Y at the inlet fitting). I think the yellow is the vent... but could def be wrong... for now that's how I have it. Coming out of the firewall I put a short hose and a small conical air filter.

Thought I already posted this, apparently not. But here's what I've come up with: Looks like in my current setup, I've got the return going to the 'Evaporation Tube' which I would assume is the vent. So, I re-routed, the return line and the top of the filter to meet at the 'F Fitting' (Item 28), then on through the firewall on the port to the left of the master cylinder. The rest looks good.

Ok so here are some pics of the current setup. Here's an overview of all the hoses. Side view of the filter. The top line goes down, through an F fitting that just never got removed, and which is capped on one port, then is routed to the left of the compartment. The left hose is the supply which is routed down and behind to the higher of two ports on the firewall. The right hose is connected directly to the carb. Good view of where the top hose goes, Is this the vent line coming through the firewall? And here's the other two firewall locations. A view of all three firewall ports, the supply line, and the 'F' fitting that I believe used to be routed to the vapor canister. And the Weber connections. Is this not correct?

I'm gonna go take pics to share. Thx for your help, Buell. I know I got something wrong.

So where is the tank vent line?

Excellent. I'm stoked. Been waiting to do this. Hopefully someday! haha
