Re: 78 Suburban surging then dies on long grade
Hey, Richard. The new pump I put on a few months ago was a NAPA. Just got them to order in a Delphi. Who knows where any of these are made. Might be the only difference between NAPA, Delphi, Carter, Delco pumps is the box it's shipped in...
It seems like a "ticka-ticka-ticka" has showed up with the NAPA pump that I can't remember being there before. No fuel coming out the weep holes.
Wondering if the return line has anything to do with this... or the associated check valves in the pump. My understanding is that unused fuel from the pump body returns to the tank via the return line and that fuel that has made it to the carb line should stay there due to the check valve in the outlet. Maybe the fuel that the carb needs is ending up going down the return line....
Hmmm....
Hope the carb rebuild kit is in today's mail! But I can't see how the carb could be contributing to this.
