Holley 255L/hr pump on 2.8

would there be any problems if I ran the hollley 255 pump on my 2.8? I am planning on swapping to a 350 eventually but pump is on way out now. Will this work or will I have to swap pumps twice?

thanks guys

will it hurt anything? No.
The pressure regulator will compensate. Your just going to be returning alot more fuel to the tank.

But I don't feel like hunting for it!

It's an in-tank? There's also Walbro pumps; search the TPI forum and main tech forum for more info...

I am pretty sure Walbro makes the Holley pump. It is an in tank direct replacement.

I am just wondering if too much flow and pressure will damage anything

the regulator will just send the extra gas back to the tank.
You not close to any danger zones.
