CARTER 120 gph 7-8.5 psi Small Block Chevy Mechanical Fuel Pump P/N M4891

I have had the pump installed on my blueprint 400SBC motor for a month. The first drive I took was around 30 miles with no issues. Yesterday I drove it for a few miles and shut it off to run into a store. After my errand, I started the truck back up and made it a few blocks before it started spitting and spuddering and eventually dieing. I checked the motor and there was no fuel in the filter. It would not restart. I had to have the truck towed home. Once it got home It tarted right up. I noticed the fuel filter was almost full. I took it for a drive and made it a few miles and it started to act up again. I checked the fuel filter and it was barely pumping any fuel into the filter. It eventually died. ***I called carter and they confirmed they have had numerous issues with this pump and my story fell in line with the others they have heard. They are working on a solution but don’t have a fix as of yet. I asked him if I should just buy another and he said he did not recommend it. *** So buyer beware. This could leave you stranded.
