3406b pump mod help!!

Not the one I use, I doubt very much it would last a week or two on a working truck. If I were building a road truck I would be using a FASS to supply fuel and by pass the transfer pump.

Old video, but it's one of the better ones.

Yes you bypass the t-pump, mine actually gave out so I went looking for a cheaper route, and that's what I came up with. The pump I use is pretty common, but the valves and seals are not, and have to be changed in an off the shelf pump to stand diesel fuel.

Its not just the pressure, you have to have a high volume at a certain pressure when you really start pushing fuel thru those injection pumps. My electric is a 300gph at 45psi, when my engine is under full load it will pull down to around 40psi on the gauge and stay there so the pump is running full out when I'm working my engine.

 

The t-pump is a piston style pump, it runs off of the pump cam, it does fail on occasion. If you have the fuel filter base that came with the truck there should be a plug on the top side, this is where you will want to take your reading. No less than 40psi at an idle, and I think 32psi under load.

 

dude where is your engine fan????

i have never seen more people have hare troube openin up a motor lmao

 

Who's engine fan?

One person was having trouble, the little tweaks on a B/C model are hard to explain on the Internet. It's a whole lot different than throwing parts at an electronic engine.
