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?

Leaks, that's not good.
 It's also letting fuel evaporate which will cause deposits to form faster, that and it probably isn't forming a vacuumed seal like it should either. When you remove the cap it should make a psshhh sound.I also ran mine from around a half to around a quarter or so, just to keep as fresh as fuel as possible. Though it's a little more of a pain that just topping it off and letting it go from there. This post has been edited by Box: Jul 2, 2014 - 10:42 PM -------------------- 2001 Miata LS 5-speed
