Hey Guys,
I had to bring this up again as my Monte left me by the side of the road on a very busy US19 here in Fl. I had started a thread about replacing my mechanical pump back a few months ago but....
Never replaced the mechanical pump because it seems to do the job just hard starting after sitting for a week but after this last Issue I need to do something..... seems I experience some sort of vapor lock as it was a warm day last Sunday here in Fl.. (sorry guys up north) and I had not activated my electric fan I have in addition to the flex fan and had been sitting in heavy traffic for some time. She just started stumbling and hesitating a few minutes before and just stalled out at a red light and would not restart, cranked and cranked and nothing.
First i tough it was loss of spark but tried the screwdriver test and got zapped... realized after getting some helped by an officer and a passer by to get her over to the side of the road that after it cooled for about 20 minutes before calling a tow truck I tried again; pumped and pumped the gas pedal and she stumbled an then started running rough but got smoother once I got rolling away from traffic.
I fairly sure I got some sort of vapor lock as temp went up to 200 F after it stalled with no air circulation, it was at 180 while in traffic... not that hot I thought
Got home let her sit for about an hour and started right up and ran fine, I do notice that once parked when hot and I go back to start her after 10/15 minutes it give me a very hard time to start.
Anybody out there gone through this? I think rerouting my fuel lines and adding an electric pump might fix my problems, they only reason I had not is because Electric pumps are loud unless in tank.
Looking foe some suggestions on a good electric pump will add a regulator also.... I am running an Edelbrock 750
Thanks,
