Yep!

I use one of these for my cab suspension fed from the same port after the protection valve as the original that was run over to the manifold valve. Push to inflate the cab suspension, pull to deflate thru that sintered bronze filter. The hydraulic manifold has 2 separate air inputs, one for...

Its possible… you have another regulator on your second engine to play with? A quick test for the return line would be to simply connect a different line to the regulator output and run it into a bucket to take the installed line out of the equation…

80 PSI at idle? Does it go up any when you rev the engine to high idle? Depending on where you look the pressure spec can vary. I have seen A0 specs from 7.5 minimum low idle to 65 psi max high idle. Are you sure the fuel return line or reg at the back is flowing properly? just came across...

As i recommend to all, i would still suggest you measure your primary fuel pressure:) It may be holding prime, but if the main fuel line is leaking its fuel back to the tank it could take a little bit of running to clear that air out of the system. Airleaks show quite clearly on a primary...

yep, no timing, the pump simply provides a regulated feed pressure as commanded by the ECU. The ECU controls injection timing same as on any other EFI vehicle, using that HEUI feed pump pressure to actuate the injectors instead of a fixed cam timing on the MUI engines so you get variable...

Sort of. Remove separator primer all together, Install ford 60 PSI pump and filter module(has a filter and water/sediment drain on the bottom) from a 6.7l power-stroke, at tank to feed up to filter on engine.. connect fuel line from near tank pump up to input of filter on side of engine. Wire...

Well it would be the electric fuel pump and filter assembly used on the ford power stroke pickups…

Yep, that holds the Oring in place….

i wouldn’t “Add” a pump at the tank, I would replace the mechanical lift pump in the governor/HEUI assembly with a 60PSI feed pump and filter at the tank(All electric, no mechanical pump at all) Just so happens Ford makes one of these:) or I would source an electric pump that will keep my...

I would say a standard small gauge Oring would probably work OK…

Yep, thats it, they made it real easy on the 3116 with a 1/8” npt port. Had an old oil pressure gauge from the junk drawer hooked up in a few minutes… IMO, this is something everyone should check whenever you change filters… or install a dedicated gauge… I don't think I can possibly count...

Yep, there are a couple ways to do this that do not involve the very expensive and hard to find cat tools…

2 is one, one is none…:)

Yea thats a lotta weight… have you taken individual axle weights? Balance too far outta wack will really show tire wear running a single CTIS pressure across all 3 axles… ”Your junk is big and heavy” Waaaay TMI…:)

Yep, on the rear of the main filter. I just had someone share a video with me of their 3126 fuel pressure problem, sampled from aft of the fuel filter. Getting ~15 psi at idle and barely passing over 30PSI at 2000RPM, so something is wrong in their neighbor hood…:(

It should be farther to the rear. the test port should be on the line between heui lift pump and secondary filter(metal pipe/line). They usually have test ports at the input and sometimes at the output of the secondary filter, which is near the back of the cylinder head In the LMtV install…...

Primary pressure is created by the fuel lift pump in the HEUI pump. There should be a T fitting on the hard line between the HEUi pump and the main fuel filter. Mine was an 1/8NPT Port with a pipe plug screwed in. You can use a simple mechanical oil pressure gauge but you need a needle...

What year and model truck do you have?

OK, sounds like it mostly held its prime, now you need to hookup a primary fuel pressure gauge to insure the lift pump is doing its part. Should have ~10PSI when cranking, ~25 at idle, ramping up to 60 by around 1200 RPM… You could have a perfect prime but if the lift pump isn’t pressurizing...
