musccoo 82 Report post Posted February 10, 2015 So my FPR in my e30 was leaking so I took it off to discover a munted O-ring. Now I have it off the car I'm wondering is there an easy way to diagnose if the FPR itself is broke or not? (I suspect it is - horrible fuel consumption, can smell fuel quite strong when car is running, and cuts out when sitting in traffic on really hot days). I have a hand vacuum pump so could connect that to create a vacuum, but then what could I do? I suppose probably the only way is with a pressure gauge? I don't have one so was hoping to avoid if possible.. Cheers guys Quote Share this post Link to post Share on other sites
