Does anyone know what years and makes use the bosch fuel pumps that are in the 78 280z's. I found out that I need a new pump and dont want to get the newer master type again. Thanks

75-83 280Z except turbo. Also 77-80 810 and 80-84 Maxima exc. diesel are all the same pump.

Awesome, thanks sblake. I will see if I can find one at the local pick and pull. But first I am going to try and change the regulator back to the stock one and see if that fixes it. Also I found this link yesterday so I tried it and the pressure goes down slowly not fast, hopefully it isnt an injector.
