Subject:      FP Regulator Life Expectancy?
Content-Type: text/plain; charset="us-ascii"; format=flowed

With the Vanagon hitting the big 200k, I was wondering what the life expectancy of the 2.1's fuel pressure regulator is. I'm sure this is the original one and since the rebuilt pump was installed last May, the symptoms probably aren't in that area. Now that I have a gauge on the fuel line, when I hit the ignition key, it jumps immediately to the high 30's, but during a drive of any length, at idle, the pressure is down in the low 20's and often oscillates between low 20's and high 30's despite no change in vacuum. Anyone wanna take a stab at this? Wiring on this is pretty solid, but does the sending unit need to be grounded to give accurate readings? I'm tied into the T towards the rear of the motor, but currently don't have the VDO sending unit bolted solidly to the block. Since the rubber fuel line hoses would seem to insulate the T from any ground, could this be the issue?

Thanks for the advice.

Max
