Bad FRPS?

[P Machy]

How many of the 03/04 Cobra guys here have had a Fuel Rail Pressure Sensor (FRPS) go bad. Mine died on my Cobra yesterday and I'm picking the new sensor up tomorrow. I also called Kenne Bell to get one of the metal diaphram discs they sell. I have read mixed results on the effectiveness of the disc actually keeping the FRPS from failing again. I figured it was worth a shot though. Has anyone here tried this part and what results have you seen?

Best part was that when I called them to order it, the said they would just send it to me free of charge since I have purchased from them in the past.

Maybe the guilt of charging $12 for a washer has finally gotten to them?

Do you have the stock eaton or ported or twin screw?

I have a Steigemeier Stage IV Ported Eaton, T/B & Plenum. Running a Steeda 2.81" Upper and a Metco 4# Lower. I see right around 17.5# of boost.

My buddy that works at the Ford Garage I got the new sensor at told me that Ford uses it on their DOHC engines and that they constantly change them out on Taurus's.

Sounds like too much power for Viper ED!!!!

Wonder if it is a Ported Eaton deal with the FRPS going bad?

Hope mine never failes me...going strong with 35k miles.

My car only has 14k miles on it. From what I can gather, it's a drastic spike in fuel pressure that seems to cause them to go bad. I have a Boost-a-Pump on my car, which may of contributed to it. Funny how Kenne Bell makes the Boost-a-Pump and they are also the ones that came out with the supposed fix for the FRPS. Really makes you wonder if the Boost-a-Pump is the real culprit.

LOL...it sort of makes sense.

Havent really seen one fail with the stock eaton. Know a few with over 60k miles...one of them with over 600 runs.

What amp and setting on the boost-a-pump?

I'll have to look, but if I recall it was around the 30% range.
