Excellent. Thank you very much. Longevity is a key issue on these pumps and keeping each other informed on reliability is the key to that. 54psi is a real good number especially after that much time.

You're welcome Scott! Oh, just to be accurate about 'time in service' for the Bosch pumps on my car, it is since this thread was started in 09. I saw what Andrew wrote concerning the pumps that came with the replacement pump/sender assembly and just ordered up the Bosch pumps before I did the transplant. So I have 4 yrs and about 23k miles of usage on the Bosch pumps.

Pardon me for "axing" a dumb question, but is that 54# reading with or without the engine running??? If you jump the pumps with the engine not running, that would be one thing. But, with the engine running, the fuel pressure regulator should be clamping it at around 50-52, no? 54 seems on the high side, to me.

Sorry, that 54 psi is a KOEO reading.

Yes, with the motor running the psi goes down to a reading of 50 psi at idle speed. I just figured that if I see 54 psi doing the KOEO test & a 50 psi at idle speed that she's good to go?

Ah! That makes sense now.

Make sure you replace the plastic hose connectors. I replaced my pumps five years ago and was at a car show yesterday. When I attempted to leave she wouldn't start, she had been a little down on power earlier in the day but I thought it just needed to be ran harder since I hadn't driven her in awhile. I pulled the pumps today and found that the hose from one of the hoses was off the pump and the plastic connector had failed. Lesson learned!

Is this the Pump and is this a legit place that isn't selling a knock off?
I think that I might just replace the fuel pumps as a preventative deal for only $62 delivered from flebay. I might use this pump on my Mastercraft X2 Indmar Boat if the fuel pump craps out again. Removal of the pumps seem relatively easy and fast.
I don't need to be stranded for a $62. fuel pump.

Did you have a pump failure or did you replace as a precaution?

How long have you had it in? I looked at the reviews on google for the Bosch and the Airtex and they were both in question. The Bosch seemed to a good choice because it is designed as a turbine pump.
