Yes, I know!!! On my Bayliner that is blue and white I buff that every year but it's a quick process. This has set for at least three year and I have to wet sand with 600 grit first because the compound is not cutting it.

Gas Cap O-ring

I hope someone can help me: When I removed the gas cap the other day the old o-ring was broken and just hanging on so I went to the hardware store today and picked up a new one that's the same dia. - about 1/8" (0.135").

Without the o-ring the cap screws on all the way:



But with the o-ring it does not screw on all the way and seal:



Do I have the o-ring in the wrong place? Do I need a longer one that will sit down by the chrome cap?



If anyone could snap a pic or give me some guidance I would appreciate it!!

Thanks, Steve

even though it doesn't screw in as far, i would think its sealing as it is compressing the o-ring.

Thanks for the reply and I would agree except that since I removed my filler, so I could buff around it, I'm able to plug the return line and blow into the fill side and I hear it leaking thru the threads so it's not sealing, it actually seals more without the o-ring than with it.

Thanks for the pics, yes I have it in the correct place. Like I said, I measured the diameter of the o-ring and it matches the original (0.135").

When your cap is screwed on does it sit tight to the black base or is it raised up with a gap in between, see my pics as to what I mean?

Thanks again, Steve

If you go to the hardware store please let me know what size o-ring you purchase.

Also pay attention to the before and after, you won't be able to check if it seals like I did. When I unscrewed mine the o-ring was already broke, it was just hanging.

Does a boat required a sealed gas system like a car or is it just to keep water out?

My cap sits up a bit since the o-ring makes contact before the cap does. I will let you know about the size when i get one. I am not sure about the sealed system. I believe prostars have a vent. Perhaps someone else can weigh in.

Mine sits up a bit (if it went all the way down, it would hit the heads of the screws that hold it into the boat; they stick just slightly above the flat plastic surface of the filler tube).

Remember that the cap is also the vent for the tank, so blowing through it you may be hearing the air going through the vent...
