I need some information concerning the fuel system on my truck. As you can tell by the questions, I have several fuel leaks that I need to deal with. Thanks to all that reply.
What seems to be the best fuel line to use for the flex lines. (at the firewall and at the transfer pump)?
Is the transfer pump rebuildable or is it a replace only?
What is a good source for a delivery valve socket?

 

Use Marime grade fuel hose for supply and return The transfer pump is rebuildable but the kit costs more than the new pump the new pump is around 80.00 from Cummins. Delivery valve socket from Cummins or Snapon
