msd 2225 fuel pump

[Kroner]

How do you think this pump would perform on a 1st gen? Ive had one for a few years now and figure its time to use it. It looks like I will need a regulator for pressure. Here is what is written about it.

Multiport EFI systems require a stable fuel supply to maintain best performance throughout the engine's rpm range. This high pressure and high flow Fuel Pump features a roller vane pump mechanism which is extremely resistant to clogging and jamming. The pump mounts in-line (out of the fuel tank) with two supplied cushioned clamps for a quick and sturdy installation. The nipple inlet is 3/8" with a 5/16" outlet. The wire terminals feature brass studs for secure connections. Made in the USA, the pump is ideal for use as a "booster" for nitrous oxide applications, or as a stand alone pump for multiport EFI systems on engines up to approximately 500 HP. Capable of 43 gph at 40 psi.
Approximate flow is 43 gph (282 lb/hr) gasoline (specific gravity 0.788) @40 psi and 12 volts/5.4 amps. Has 3/8-in. hose nipple Inlet, 5/16-in. hose nipple Outlet. Includes 2 cushioned mounting clamps and 4 mounting bolts.


Notes:

THIS PUMP IS FOR FUEL INJECTION, SPECS ARE AS FOLLOWS.
AT 30PSI 43GPH > 80PSI 39GPH

It should keep up with a VE no problem.

I'd check and make sure it's rated for diesel fuel.

Another thing, the lift pumps are designed for high FLOW. Think of the cavern of the IP vs the rail of the EFI car...

I think the 5/16" out won't help matters...

My 7.3 lift pump is 5/16 in and out, and it can maintain pressure easily, sucking on the stock fuel line. Thats around maybe 200 rwhp. Maybe at 400 it won't keep up. As long as the pump can maintain pressure at the inlet under load, it doesn't matter if the pump makes 40 gph, or 100 gph. The same amount of fuel is going thru the pump. I'd say use it, you already have it. Build the fuel system with the regulator, and if the pump can't keep up, the fuel system is in place to accept a bigger lift pump.Jmo.
