Ranger Posted October 4, 2006 Report Share Posted October 4, 2006 Most likely the FPR. It takes less than a minute to check it. Link to comment Share on other sites More sharing options...

BodybyFisher Posted October 5, 2006 Report Share Posted October 5, 2006 I agree with Ranger, FPR.... Take the vacuum hose off of it and see if you have fuel present...

Fretbuzz470 Posted October 5, 2006 Report Share Posted October 5, 2006 Yeah most likely FPR...If taking the vacuum hose off of it doesn't produce gas leaking from it. Try running the vehicle w/ the Vacuum hose off and pluged. Some times when they are just starting to go bad they only visably leak while higher running pressure is constant.

If you suspect it might leak under load, I certainly wouldn't drive it with the vacuum disconnected!
