Walbro GSL392 Walbro High-Pressure Inline Fuel Pumps - gsl392 - Free Shipping on Orders Over $99 at Summit Racing

Be aware of the amazon and chinese POS knockoffs!

I have been very happy with it so far. Ran a Bosh 044 prior too and it was garbage...went through 3 of them in 10k miles.

I had a Walbro for a couple years. It became very loud towards the end. I bought a super duty pump and have been happy ever since. Good pressure without the noise and it has a lifetime warranty as a bonus

If you want to stick with an air/water separator, go with Air Dog. I've replaced mine twice in 8 years on my Dmax and they've sent a replacement pump each time no questions asked.

Okay thanks guys but if I don't go with a air dog or fass I'm going to go with dual superduty pumps but my main problem is the filter housings as mine were built into the pump now I won't have any

What injectors are you running to need dual pumps?

That's what I did and a single SD pump works fine. Of course my injectors are still stock. I didn't see any need for the complication and expense of dual pumps but I can add one later if necessary when I start the inevitable serious mods. Biggest problem with my installation was getting the filters mounted high enough to avoid getting clobbered by rocks.

That pump will drop pressure under load. The gsl392 is whisper quiet and keeps up no prob with 250/200 just fine..89$ it's hard to beat

I've got the super duty pump on mine with the sinister diesel regulated return and baby swamps no matter the setting on my chip I've never seen it drop pressure

Dual pumps will help keep the pressure up, but won't give you more volume. The only way to truly get more volume is to run a bigger fuel line from the pump to the heads. But, in my opinion, even that won't truly get you more volume because you are still trying to force all that fuel through the tiny hole in the fittings on the back of the heads. Black Widow makes a fitting that replaced the fuel rail plug in the back of the head that you can hook the fuel lines to.

In my opinion, this is the only true way to actually get more volume of fuel all the way to the injectors.

.
Bill, one of the concepts that I'm trying to understand is the idea of "all that fuel." I don't think we're burning a tenth of a gpm of fuel, hardly much flow and there shouldn't be enough velocity to create much of a pressure drop at all. That may be a tiny hole, but the required flow is pretty tiny too.

I'm new here and not trying to start a pi****g contest, just want to understand this.
