Performance Fuel Pump Upgrades

Hey, I looked around and stumbled upon the tech article on the fuel pump upgrade that used to be sold by MN12 Performance. I looked around for other options and stumbled on these:

Quantum Fuel Systems 340LPH:

And of course this Walbro 255LPH:
http://www.highflowfuel.com/i-103840...ategory:173044


My question is are these good pumps? Do these kits work or are they of the universal variety? Anyone have experience with them?
I've heard only good things about the Walbro 255's but nothing of the Quantum, though the Quantum is cheaper and is a higher flowing pump and claims to be superior to the Walbro.

I'd like to get some insight since I'm doing a approx. 350-400 crank HP (initially) supercharged application and don't want to run that Vortech T-Rex crap.

The Walbro 255 is a common go to pump for builds here. It will serve you well up to around 400HP, if you plan on going higher eventually you'll want something bigger. I'm currently running a 405 lph FORE pump and 60lb injectors for an E85 application.

At 40psi and 13.5 volts:

Flows 440 lph in Gasoline
Flows 405 lph in E85

I have no experience with the Quantum pump. I ran a Walbro 255 for 10 years with no problems, then changed to an Aeromotive Stealth 340 pump a couple of years ago. It has also worked well for me. The Stealth 340 is a turbine type pump, so it takes slightly longer to "spin up" than the Walbro, with the result that the cranking time to start is a bit longer. Seemed odd at first, but I got used to it.

I'll probably go the Walbro route then. I hear that in the import scene as well. Walbro it is. Thanks guys!

I've had a Walbro 255 for years. Not that I need it, but I needed a fuel pump and thought I'd might as well get one that could support a Vortech S-Trim, big dreams and all.

Just FYI, they're currently available on Amazon, Prime Eligible, for $61.74

I'd love if I could find a Walbro and the whole install kit for that price, but I think High Flow Fuel has the best price that I could find.

Quantum claims their pump is made at the same factory as the Aeromotive Stealth 340, but just re-branded and sold with a lifetime warranty. Now that sounds really promising and for 69 bucks with free shipping for a whole kit. These pumps look like a really good option...but you never really know. The few reviews that they have are solid though. Worth a shot?

I put a walbro on mine when the complete fitler/hanger/sender unit from rockauto died. The factory one was going, above 3,500 it had no oomph. then the one i bought, and paid just labor to put in..failed, so 300 bucks later plus a friend helping me with an employee discount and going halfsies on it too, i got the walbro pump for about 60 dollars, and had Pepboys install it. The car loves it, it feels beefier in hand than the OE type.

Install kit is $24 on Amazon. So still $10 cheaper.
