I am currently searching for the correct to use for my L28ET set up. The list was already down to the Walbro 255lph external fuel pump but I wasn't sure if it would be enough for my application. I am planning on 15-25 psi of boost and my fuel set up is 550cc top feed injectors on a custom fuel rail, FMU, AFPR, -8 main and -6 return. I stumbled accross an MSD2225 pump which can pump a little bit more than the Walbro. http://msdignition.c...s_id/40016/2225

I am aiming for 400-500hp. Pardon me as I don't know anything about fuel delivery and I have searched about this MSD pump but didn't get the info that I needed. Please advise.

Ok so I was wrong, the Walbro pumps more than the MSD. Mods can close this thread now.

I would not trust a Walbro for 500 HP. Get a Bosch 044. Fuel = Insurance when boost is involved.

If your going to drop some coin, I've got an Aeromotive A1000. No matter what I do that FP will handle it all.

phil, where did you buy the A1000,at a good price? I`m undecided on either the 004 or the A1000. thanks.

Yup, big sucker, though. Vibrates and is kinda loud. If you can hear it, though, you simply haven't pressed the throttle hard enough.

The A1000 is my next pump. I am still running a Walbro but have had 2 fail on me. I am going to replace it within the next 6 months with an Aeromotive.

I'm running a Bosch 910 in my L28E. I don't know how much hp it will handle, but its way quieter than the shitty Walbro I was running, and hasn't let me down yet.

I had an aeromotive in my z, and that was the loudest damn fuel pump I have ever heard!

Look in my SIG!!

Whatever you do don't get a MSD pump. I've installed two and both have failed within 6 months. After reading online I saw I'm not the only who had them fail. I've had way better luck with walbros, not the MOST reliable pump but tons better than MSD in my opinion. An aeromotive or bosch 044 is going to be your best bet.

I got mine off e-bay, under $100 I think. And yes its, I dont know if "very" is the right word?..........yeah, Its very loud.

To everyone considering one, just hang it under the car (if you have room) and isolate it with rubber standoffs. That'll help a bit.

Where's the 044?

[Project Z]

Wow thank you guys! I think I'll either get the Bosch or Aeromotive but really depending on my budget. I haven't found an Aeromotive pump for less than 300 but I will keep looking.

Take a look at the flow vs. pressure chart for the A1000 - as I recall it flows a sh#tload at 43.5 psi, but it drops off pretty dramatically after that.

Here's a chart:


It's probably still enough, but probably not by as big a margin as the 43.5psi numbers lead you to believe...
