1999 Forester gas leak while fueling

[wduzak]

Newbie back again. This time I've got a gas leak. When I'm filling up I get a small puddle that appears after a few `gallons go in and it seems to be coming from filler neck. When i stop pumping gas the leaking stops. No further leaking until I go to fill up again. I am considering replacing filler neck and looked at a couple of videos but there is not one of 1999 subaru.It looks simple enough but should I leave it to mechanic? I'm thinking about buying fill neck before hand an  let someone do the work.

When I get under car (not on lift or jacked up) i can see where it enters rubber hose to gas tank but everything else is obscured.

Sorry to keep pumping you guys for information every other day but any suggestions?

I live in Tennessee and I have emissions testing which I think includes a test on the fuel line integrity from gas cap to tank. It passed fine, but when i went for first fill up the leak appeared.

Thanks

Filler necks seem to be an issue with these cars. If air is entering the gas tank, it can affect the evap system, and it can allow excess dirt to enter, which will eventually clog the sock and shorten the fuel pump's life span as it pulls more current and works harder trying to supply sufficient fuel flow.

 

Only you know your limitations. A mechanic will charge a bunch to fix the issue. The neck should be bolted to the body, then feed into the tank. I dunno if you have drop the tank on these or not as I'm not sure how the tube feeds into the tank. Some cars you can unbolt the flange area behind filler hole cubby, unhook the vacuum line, then slide it down and work out of the tank.

 

If you have to drop the tank, run it as close to empty as possible every extra gallon will make it a nightmare to work with, even if you manage to get a section of wood attached to a jack and the tank strapped to the board. Also, do yourself a favor and get new tank straps if it needs dropped. You can tin snip the old straps and save a bunch of time. Throw some anti-seize on the threads of new straps and they'll always loosen. It'd also be wise to have say 1/2" or thicker plywood sheet, like 3' x 3' and blocks under each corner. This way, if the tank slides of jack assembly, the wood will catch on the blocks and entire tank might only drop a couple inches vs. falling on the ground which can be bad, not to mention near impossible to get off the ground while on your back if it has a half tank of gas in it. Also risk damaging fuel lines if it drops too far, too quickly.

I recently pulled a filler neck off of a 98 Forester to put in my 98 impreza (perfect fit btw) and you can definitely do it without dropping the tank. the worst part was drilling out the 3 bolts that hold the top of the neck to the body. You might want to splice the little vent lines instead of trying to get at the tank end of them.Good luck with it!
