So my pump got ridiculously loud yesterday, then today I started it and it was back down to its normal sound. Normally it runs at a noticeable volume, but yesterday I could hear it very loud over my car exhaust. It only has 7k miles on it, I doubt it would be going out already, but that's possible. I used the GSS342 for the Mazda mx3. The car seemed to be idling strangely, but still accelerated fine, and my voltage output was at the normal 13s according to my gauge. I didn't check the voltage at the pump though. Could it have been a restriction or ventilation issue?

Could be the filler neck that's the culprit. If you were to fill it up to where it'd normally leak you might be able to see it. Permatex makes a fuel tank repair kit I believe.

Permatex makes a fuel tank repair kit I believe. there is also a gasket around the filler neck if I recall correctly. I'm pretty sure I removed the filler neck when I dropped the tank last time to dump the old fuel. So it might be that I need a new gasket and shouldn't have reused the old one. My plan is to fill it up all the way to where it leaks, since it's been about a year since I did it will clean off whatever dust is around that area. I haven't had a lot of luck with tank repair kits. They are made more for punctures, I tried all of them on a friends tank and none worked longer than a week. Silicone gasket maker might do the trick if I can find a fuel grade one. This post has been edited by match220: Jul 3, 2014 - 12:04 AM -------------------- -Jay
