I have a 1994 Z28 with fuel pump issues. The fuel pump will just quit working,,Sometimes it might be a week or a few days or several times in like 20 min. I have replaced the pump 2 times,replaced the relay behind the driver side kick panel,rewired from the pump to the junction behind the seat.I am totally at a loss here!!!! Also is it possible to replace the pump with a external pump?

 

maybe if you post a thread in the fuel section it will get some more views and responses. im clueless to your prob but there are a lot of smart people on here, just got to post in the right section
