I was thinking to use a set of 12 volt electric fuel pumps made for gasoline engines to pump diesel from the fuel tank to both diesel engines in my boat .
Are the gasoline pumps going to survive diesel oil ?
Or am I better off with so called diesel pumps ?
I found that the gasoline pumps are much cheaper ,or is that for a reason?

Honestly I would look at the Holley Blue pumps, they can handle gas or diesel...For the price they should be fine...not too expensive...

 

What type of fuel volume do you need? What motors are you running?

 

mount them low so they have a good head, and remove the brass screens in the pump housing, (they can get clogged easily with cold fuel) then shim the regulator spring with at least a .040" shim washer to provide good psi, no problem. I use the larger housing "Black Holleys" under my truck and they hum along endlessly without issue cold or hot.

 

I have two Yanmars 6LY2A,s with 440 hp/at 3300 rpm a piece ,these are 5,8 L 6 cilinder inline 2 valve ,s with a line pump,they have 880lbs/ft a piece ,and use 90 Litre /hour (24 gallon/hr) full throttle.

I am going to turn up the fuel at the pumps and hope to reach about 500 hp a piece ,so I guess 28 gal/hr ???
