Default Fuel Pressure Regulator

Is there a diaphram in the fuel pressure regulator of a 95 LT1? If yes is it replacable? Thanks.

Yes, There is some form of diaphragm because it can leak. Don’t think you could get in there and part is probably not available.

The 95 FPR is different then the L98 one, I dont believe it can be rebuilt like the early ones could

Normseven,
The stock 95 fuel regulator is not repairable unless you want to buy an aftermarket adjustable AFPR kit to convert the stock unit over so you can access the diaphram in the future. You have to destroy the stock crimped belly clamp to get at the diaphram. AFPR kit comes with a diaphram,spring,aluminum hat,and an adjustable threaded belly clamp for serviceability or you can just buy the whole AFPR complete ready to go from TPIS. Modifying stock units is what TPIS does to make the AFPRs they sell.They also list and sell the parts needed to modify one yourself if preferred.

Thanks guys for the response's. My 95 does not fire right up but cranks a bit when I first start it. I don't have a lot of tools, but my neighbor does and thought it was an replaceable part. Anyway I do have the FSM and will look into it. If there are any quick checks you know of let me know. Again thanks for the info on the FPR.
