    Having serious vapor lock/ fuel boiling issues.
    Need a recommendation for a DEPENDABLE full time electric pump replacement for the factory mechanical fuel pump.

    So you're saying your fuel pump is the cause of this boiling over and vapor lock? Would you mind posting a picture of your engine bay, specifically your fuel line and carb?

      I used the red Edelbrock 4-7 PSI...
      They have them at O'Reilly's or AutoZone. They're quiet and work fine. I just recommended one to another member who emailed me a few days later and thanked me for the recommendation as it was quiet and worked fine for him as well...

        I will be trying one as well, possibly on the van in the near future. I think they were like 62 bucks at O'reilly's

          They used to be cheaper like 42 but they jumped up in price pretty quickly over the last year or two...

              You can do just fine with a pump mounted on the frame rail in front of and below the tank. Make sure to run a return system with a regulator if you want the best of benefits from an electric pump.

                Do you have a spacer under the carb?

                  Probably one of the most overlooked things ever and will solve 90% or more of these type problems.

                    I betcha a simple return line will solve all your problems while keeping your mechanical pump

                    Or a fuel return type filter. @Tonto7 when are you experiencing problems? Extended cranking after sitting for days to weeks? Hot soak? (shutting it off and hard to restart after sitting a while) Or are you having issues while driving?

                      Adding an electric fuel pump is a band-aid solution.
                      You should not require a electric pump to keep it from vapor locking.
                      You have other issues you need to solve first.

                        I agree with that, BUT it sure helps eliminate problems with ethanol laced gas. People who don't have issues don't know how easy gasohol vapor locks under the right circumstances, plus there are areas of the country that use over the 10% limit a lot of us have. An electric pump with a good return system does help in those situations. But I do agree 100% that the SOURCE of the vapor lock should be addressed even before the addition of the electric pump and return, otherwise you still may not fix the problem.

                          I ran 3 external pumps and all mounted lower than the tank. All three left me stranded. I ran a walboro pump twice.

                          Paid the price and switched to an aeromotive phantom in tank pump and have not had an issue since. I learned my lesson and would never use an external pump again.

                          Sorry you had trouble, but the fact is a LOT and I mean a LOT of vehicles have had great success with frame mounted external fuel pumps both in the aftermarket DIY world and right out of the factories. In fact, some new vehicles still use them, so that puts their use well into the millions, perhaps even tens or hundreds of millions since electric fuel pumps have been put in use.

                              I dont like hearing this... i have been having fuel percolation/vapor lock issues... never had them before installing cam, lifters, cleaning the engine (internally). Added 1/2in spacer as well...

                              Hot vegas heat, hot asphalt, hot engine bay and the carb doesn't get the fuel.... my car has maybe 50 miles since the new parts all installed because percolating/ vapor lock issues.

                              I'm looking at adding an electric fp and running a return line as I dont know what else to do.... I'd love for you to share your wisdom with a young grasshopper who just wants to drive his car again lol. I really don't want to drop the gas tank in my garage for a the return line though. :(

                              You do not need to drop the tank to put a return line in.
                              Use a fuel sender/pickup unit that has the 1/4 nipple for a return line.
                              That said, I agree with 512stroker especially because you wrote this didn't occur before you changed cams etc.
                              So what's different now?
                              not the things listed in the beginning here.
                              On what basis do you know the carb is not getting fuel?
                              I'm not being an ass here. I'm asking what the basis for coming to this conclusion is because vapor lock can occur in different locations and show up in different ways.
                              Using the specifics, one can begin to narrow what/where the issue is.
                              If you have a thread covering this - then just link it.

                              PS. Off topic Speaking of heat. Route the output wire through the clip.

                                And where is the fuel filter?
                                20200728_210855-jpg.jpg

                                I'm headed out but you can do a search here for how Chrysler recommended mounting the fuel filters to help let vapor escape.
