Re: Why do I have to prime the pump?

Do these cars have one of those residual pressure-holder thingies...
(laugh) I don't know why I can't remember the name. If you have a small
leak in your fuel lines somewhere, or your... darn it, whatever that
thingy is called.... isn't working right, then this might be your
problem. On my CIS Rabbit, I installed a relayed fuel pump switch
because I didn't feel like replacing that thingy (the new one, plus
lines that were rusted away, would have been several hundred dollars, or
approximately what the car is worth).
