Electric fuel pump recommendation

Hey everyone. I am looking for a good electrical fuel pump for the ol' CUCV and I was wondering if anyone has had good experiences with certain brands. I've had a few go bad because I'm cheap. No more.

Perhaps a fully contained lift pump and filter assembly to go straight to the IP?

It has been said here that the pump used on the 6.5TD is the one to go with.

I've been running a Walbro FRB-22 pump for a couple years. It was a little pricey at $120, but has a built-in prefilter, pumps only on demand, and can handle WVO and B100. There's a cheaper version called the FRB-5. It's worked well for me, but you have to watch when you clean the prefilter that you don't lose the o-ring or it will start sucking air.

thanks, i had the same question

Where is the FRB-5 cheaper? I can't find it for anything less than $130 shipped. And aside from passing a stricter salt spray test, what makes the -22 better than the -5?

On this page Auto Performance Engineering - Walbro fuel pumps and more the -22 is actually cheaper for some reason, but still more than the $120 you paid. Was about to spend $130 on the -5 but would love to save anything I can on this.

I'd suggest you read the entire thread above... lots of info on this modification there.

I used an Airtex - Diesel Electric Fuel Pump Kit, Part Number: E8153 $60 on two 6.2's... got it at Advanced auto... most of the main autoparts retailers have it.

AFAIK the Walbro FRB5 is discontinued and replaced by a newer model ...I think anyway. For a CUCV A factory lift pump from a 1993 Chevy K3500 6.5TD is the best LP to use as it is designed to work with a DB2. If you put a LP on with to much pressure it could screw with the cold advance.
I personally run an Airdog but it is way unnecessary. I had it laying around.

The FR series pumps are still on their website, I think it was the 2000 and 6000 series that they replaced. And I think their output is adjustable to match the lift pump. I mostly want it to simplify other fuel system operations like bleeding and draining, and if I get one at all I want one that will last.

I seriously considered the Airdog brand to replace most of my fuel system, but the 500 dollar system they were selling was a lil' too rich for me.

I got the 22 series off of a boating website for $120.

Airtex E8153 (let me verify the model #). Its the correct pressure & volume for our trucks. Its also very WVO tolerant.

I got one for 100$ from Pureflow. I thought the one on my Dodge had failed and it was the ****ty workmanship at Lee's Auto Ranch in Ellington Ct so they let me keep the replacement one they sent for 100$ since there was nothing wrong with my original one other than a horrible install job.

Digging up an old thread...

I have come to the conclusion that Carter vane type electric pumps are not a good match with the DB2 injection pump. The previous owner of my rig installed one, and with it's 25+ psi output it was too much for the DB2. So I figured I would install a regulator and plumb the bypass into the return to the tank. Well that Carter flows so much that with the regulator turned down to 14 psi the pressure pushing the excess fuel back in the return was almost 10psi. So the Carter and regulator are getting pulled and I am installing a Walbro FRB22-2

When I went with an electric pump, I just bought a pump from a 93 I believe diesel van. I placed the pre fiter assembly under the skid plate just in front of the fuel talk on the inside of the frame. It all fit perfect and has worked great so far. I simply wired it through a relay connected to a Hot when when key on circuit in the fuse box is energized. Being as it is designed for a GM diesel there are no pressure issues and when needed, the prefilter change is no issue. Hope this helps!
