Dual walbros?

[7.3zombie]

I'm starting to get everything together to do a fuel system upgrade and I was gonna do dueling stockers and a fuel/water separator pre pump and a fuel filter(napa 4770 base and 3528 filter) post pump! Upgrade to larger 6an from tank to engine , harpoon, hutch! Etc etc!! My question is I can get two REAL Walbo gsl 392 fuel pumps for $150 new so are these good reliable pumps? Has anyone done dual walbro pumps? I gonna be doing Rosewood stage II injectors and a GTP38R in the next year depending on cash! I have a TS tuner with tunes from php, exhaust, intake! Thanx

Why are you going thru so much work for stage II's?

Just cause I know my self all to well I'm will go even bigger later! Plus doing this fuel system can't hurt and it won't take long to get done and not cost to much! I've priced everything out already!

Fair enough. Good luck then.

I've always preferred the Bosch 044 fuel pumps, as they are rated for diesel fuel where the Walbro 392 is not. Also, when you're plumbing the fuel system, be sure to run the pumps in parallel with each other, not in series. This will ensure max volume and pressure to the cylinder heads.

I have looked at those Bosch 044 pumps too but they were alittle pricey! I though tht I'd get two walbro pumps cause they cost less then one Bosch pump or a stocker! This guy I know sells them! I planned on running them in parallel as will! My fuel system is like a mix of the home brew fuel system and maintains dual pump setup! Thanx for the info

I've been running the Walbros for 4 years now. The higher fuel pressure is the best point with them. I have been able to run 105psi in the rails from idle to 3000rpm.

Why wouldn't they be rated to flow diesel? Casserly even sells this pump on his website, and every time I see one listed its for a diesel 7.3L

One walbro will flow enough for 250/100s, so I. Would think you could get away with it. If you're looking in doing the twin pumps, I'd just go with an aero motive pump for about the same price and it will flow more than two walbros.

Why you running 105 psi? Good lord that's a ton of pressure. Or did you just say you COULD run 105 psi?

Why not run dual stock pumps? They work great, for a long time, and can't run 105PSI which is awesome

Dual walbros isnt the best idea. For that price get fuel lab or aeromotive. And 1 flows enough for a good sized injector. Dual stockers will flow more than a single walbro.
