Maybe Part Or All Of The Problem
 

Hi Gang,

Some of you have been following the trouble I've had with my '75S. It has had a rough running problem for a week, and when the throttle is depressed more than half way and I try to rev the car up, the car stumbles and acts like its running out of gas. Today I found that the WUR is not providing fuel pressure to spec. The pressure is about 1/3 it should be when cold. Then, if I jumper around the relay on the side of the engine compartment, I get a pressure of about 2.9 bar (still about half). So, I possibly have a couple of things going on, a bad or plugged WUR and a power issue.

Also, the system pressure bled to zero in about an hour. Either a bad fuel line check valve or a bad accumulator, right?

Thanks,

Troy
