Walbro FRB-13-2 6-8 psi 43 gph

[Garbage_Mechan]

Anyone running this pump?
It has an internal 70 micron screen, 18,000 hour projected life, 1/4 inch ports. That is 10 gph more than a Facet with all the good features stil included.
If the Facet is marginal at 33 gph will 43 do it? Using Walbros hp to gph calculator it is good for almost 300 hp.

This is an interesting path for an IDI electric pump. I don’t know anything about this version, but Walbro has a great reputation for long lasting submerged electric OEM pumps in many gassers. There are a lot of folks in the Grand National community that run twin Walbro pumps to get enough fuel for thirsty high horsepower applications with excellent results.

I like to use industrial rated stuff on diesel trucks. Wes May be right and the high flow Mr Gasket / Holley pump with a regulator may be the best way, but I want to rule out any other options.....

I’m going with a walbro gsl392 since the shop truck with a 100gph Mr gasket pump can’t keep up with the 150cc ip. Figure most stock pumps make about half that much cc.

These rotary pumps use a lot more fuel because they, unlike most pumps with a fixed advance, have a hydraulic advance and is completely lubricated by fuel unlike most other large displacement diesel pumps that are lubricated by oil. This means the pump uses and returns a lot more fuel than most other style injection pumps at a similar hp level.

I hope it has a better filter than the 70 micron one listed above. That seems like WAY too course of a filter.

The 70 micron screen is on the pump intake to keep junk out of the pump. Normal filters still required between pump and injection pump.

I am running a walbro frb pump. Put it on many years ago and forgot I even did it. No problems ever.

Have you ever checked fuel pressure under load? Curious to know.

That explains a lot.

I might try one with the terrible reliability problems that I have been having with the Carter 4070 recently.

Where are you guys mounting the Walbro on your trucks?

Fwiw
Without a pressure gauge installed, on my 7k+ Alaska trip I never felt a loss of fueling with the group buy pume..( even though the filter light was coming on like a ****** in a hotel bar) I saw some egt/coolant spiking on long grades\heavy pedal usage.
I got nuthin (light wise) ever with the mech. Pump

Was that with the Walbro?

Nope
group buy transicold\faucet

Same here, and I run a Goldenrod waterblock filter in front of it to meet warranty requirements. Best pump by far (IMHO)- industrial marine pumps HAVE to be better simply because of their anticipated environment and the lives depending on them. I have it mounted on the passenger side frame rail.

I notice in your sig....you have an HHO system on your 89. Hows that working for you?
