Re: fuel pump i believe
Sure sounds like the fuel pump is bad. If you got 272k out of the original pump (without it failing or leaking), you are fortunate! I've had them run fine, but only leak a bit and others sit and idle all day, but have the fuel pressure drop to zero under load. The usual method is to attach a liquid filled gauge to the shraeder valve on the FPR, with hose long enough to tape the gauge to the widshield and then see what happens when driving it. Cheers!
