There is a much easier way to solve your problem. As mentioned above those electric fuel pumps must move fuel in order to keep cool. The return line is a very important piece of the puzzle you didn't use. No fuel pressure regulator needed!!!!!!!!
The carb only needs 3-6 psi, but if the carb bowl is full then the fuel isn't moving and the fuel pump gets hot over heats thus stops working. All you need is to use the fuel return line and problem is solved. It is just this simple go to O'Reilly's and get a brass 3 way T. Get two 5/16" size by 1/4" thread brass nipples and one 3/16" size by 1/4" thread nipple. Will need a roll of thread sealing tape also. Once all this is purchased just lay the 3 way T on table place the two 5/16" at each end of T and wrap sealing tape around the threads not getting any extra over the holes and install them into the 3 way T. Once done wrap tape around 3/16 nipple and install into the top of 3 way T. The 3/16 nipple now goes back to return line and one end of 5/16" goes to main fuel delivery line while other end goes to carb. Problem solved!!!!! The fuel flows freely, pump remains cool, carb isn't over loaded by fuel pressure, and this also allows fuel tank not to create a vacuum because of a plugged off return line. Hope this helps.

I’m looking to purchase a luv truck as we speak. The owner claims that The truck is having this exact issues. Your quote listed above seems like the best way to solve this problem. But I’m not quite following everything that I have read in the quote. Any way you can explain it a little better? Thanks Joe
