High Pressure Fuel Pump For 280Z?

The stock pump is not mechanical on a 75 280z.

 

The stock 75 pump should be fine if it is in good condition. If not, the msd 2200 efi pump is a good one.

 

As I recall, the stock n/a pump has an internal pressure relief valve that is set to ~55psi, which could be a problem depending on the base fuel pressure you want to run and the intended boost pressure.

For instance if you want to run a 3 bar base pressure (43.5 psi), then the max boost you could safely run would be 55 minus 43.5, or 11.5 psi.

I personally have had issues with external Walbro 255l pumps; I have had two fail on me in less than 1000 miles. (I run Aeromotive filters prior to the pumps) I have run them internally for years without an issue, but externally I have had no luck. I have switched over to the Bosch 044 fuel pump.
