I just bought a JAZ plastic fuel cell i installed it and ran my car then a week later i noticed the top of the fuel cell was slightly sunk in i checked the vent fitting thinking it was plugged but it wasn't. Anybody have an idea what the problem can be??

Tends to be normal with plastic fuel cells. The only cure is to get an aluminum one next time.

I had a JAZ with the same problem it's got to do with the molding of the cell. I really got to hate mine. If your thinking of changing to another look for one that has a raised area in the middle around the filler opening. Like a harwood. I know they are not in the cell business anymore last I knew but look at a pic. of one to get an idea of what I'm talking about. Hope this help some I don't know of a way to fix yours.

I've had a Harwood for over 10 years and it looks as goos as the day it was new. I havent personally seen any problems with the JAZ style (similar to Harwood design) but have seen my fair share of the RCI's look like crap and sagging. I would assume it is possible that too small of an outlet fitting on the suction side or to small of a vent could cause a problem. I always used a -8 vent fitting.
