Message Hey, since I bought this 95TT I have had some fuel related issues. It had a totally shot FPR that I replaced along with the dampener and filter. The fuel system wouldn't hold pressure until I replaced it...and the fuel pressure actually went DOWN slightly as vacuum went down...this has since been fixed.

When priming, the pump makes some odd noises. Sometimes it buzzes with a slight "radio static" sound to it. Sometimes it makes a loud bubbling/boiling water sound like if you took an air gun and stuck it in a pool of water.

The pump makes other strange noises once in awhile but I haven't encountered them enough to describe them. I was going to pull the pump to inspect it but I haven't had the time, search brought up a post with a similar complaint but it wasn't resolved.

The pump on my 91TT and my 82 ZXT make a clean WRRRRRRRRRRRR sound, and are the only pumps I have to compare it to, so the noises sounded "not right" to me.
