Diy: How To Reseal The Fuel Inlet If Its Not Sealed Or Leaking

[SargeRX8]

Well as some of you may know, my car hasn't been making the psssh sound when I go to fill up. Everytime I started up the car, I got the fuel smell in the cabin. DVS JEZ suggested its the fuel filler, the little gold thing the fuel cap screws into. Well today, I started up my car and saw the fumes of the fuel escaping from the fuel tank. This is not only a problem, but also a very dangerous one at that. Had a smoker been walking past, those fumes are sure to take a flame.

I don't have photos now but it is a very straight forward thing to do. I can get some pics etc.

What you need:

Gasket goo stuff(as long as its fuel resistant, it should be fine).

Wire brush

Flat head screwdriver

1) Pop off the fuel filler cover and remove the fuel cap

2) The metal fuel filler mechanism is simply, its just a cap holder with a metal flap. I didn't need anything special to remove mine, I simply grabbed the edges, jiggled it and it came right out. If yours does the same then this is a clear indication the damn thing is not sealed!

3) Use the screw driver and wire brush to clean off the dirt and crap under the lip of the fuel filling thing you just removed. The wire brush removes light stuff while the screw driver is good to get into the little nooks and dig that shit out of there.

4) Once that is clean, try to clean the lip that is still on the car, the black hose leading to your fuel tank. I was abit worried about doing this and dropping shit down into the tank so I just made sure to clean the outer edges.

5) Depending on the gasket stuff you've got, apply a nice amount in the lip on the metal piece you removed, on the inside(you will see what I mean, its like a U on the inside which I filled with gasket stuff). Then if necessary apply some to the black tube under the filler cover.

6) Let it set until its tacky

7) Push it back in. If I recall, the spring valve mechanism sits in with the spring on the top. Just remember the orientation when you removed it.

8) Let it dry a little then screw the cap back in and let it set.

9) All done!

Let it dry and away you go! Pictures can be posted up if needed!

Glad it fixed your issue.

I have had to do this on a fair few cars. If i can smell fuel from outside the car or in the cabin its the firat place i check.

Hey SargeRX8, can you please post pics? I'm getting similar if not the same problem you had prior. Would be good to have a visual to go with your instructions. Thanks mate.

I can get pictures but its not going to be step by step as its kind of all sealed up. Ill see if I can unseal the filler in my old car and get pix.

Guys, I'm doing this now, but my fuel filler rotates completely, so I don't know which way to put it back in...do the two small holes go at the top or bottom?

Hey anyone got a good gasket goo for this job??

I have tried performance 1 hard setting (fuel resistant) how ever it wont set.

Any ideas??

silkaflex fixes everything

[arrydjay]

yeah who ever is doing this.... dont use gasket goo.... i used the stuff that said hard setting, but after a week it is still not set. It must need heat or something and you cant just whip out the blow torch on the fuel port. Going to have to clean it all up again and use sikaflex or something.

Just ran into the same problem - awesome tutorial. Can't wait to try it out tomorrow after work!

PS: found this tutorial by 180sxnit on the Silvia forums - it's very similar to this one, only it has some pictures too!
