Fuel Pump Relay

1071 Views 5 Replies 4 Participants Last post by  Scott Kelley
I am putting an electric fuel pump into a '75 ElCamino. (LSx engine). I want to use a fuel pump relay that will sense when the engine quits and shut off the pump. I know that many vehicles had this type of relay (I presume that newer vehicles do not use this type of relay, but are controlled by the computer instead).

I'll probably get something out of a wrecking yard - I would like to get a relay AND socket.

Any suggestions as to what vehicles to steal this from? Reliability & availability are the two obvious issues that come to mind.

Again, I'm not looking for a normal relay, but an actual "fuel pump relay" that senses when the engine quits and shuts off the fuel pump.

I know that Bosch makes such a relay - used on CIS equipped cars - turn on the key, the pump runs for a few seconds, then the relay is energized as long as there is a tach signal to one terminal. I believe that other mfgs also had a similar relay, & was hoping that someone might know of an application where this relay was mounted in its own socket, and where this relay was more reliable than the Bosch relays...
