After the Lift Pump and before the IP.

This is the area to have a gauge so to see what the lift pump is doing, Right?

I wouldn't mind being able to tap into the fuel line and install a simple pressure gauge right under the hood.

Has anybody ells done this?

Any pics or video?

Yes, sorta. You want it between the filter and the IP, that way if the filter starts to plug you can see it before you are stuck on the side of the road. The easiest way is with an 1/8" NPT tapped banjo bolt, you can get them from Geno's, Vulcan, and GDP and probably some other vendors too. They list them for 24 valve trucks, ours use the same bolt.

 

Thank you, I'll check it out.
Nice.

 

smart move i put one on and realized that my filter as clogged and was getting only 4 psi normal driving with a piston lp. not good, swapped it now fuel pressure gauges are mandatory.

 

Helps you save money on fuel filters, too. As long as pressure under load is good, no need to change the filter. Mine's in its second year of service.

 

Here is the tapped bolt :

You can also get the Big Line Kit from Glacier :

or the equivalent from VULCAN :

I have some trucks that use the tapped banjo-bolt and some that have the Big Line with TEE for gauge.

I have one truck that has the gauge mounted under the hood.

It is much better to have it in the cab, because bad things can happen quick.

 

what type of gauge? one with an electric sending unit or mecanical?

 

mechanical sending unit with a needle valve to the banjo then the line to the gauge.

 

Mechanical gauge, with a ball-valve cut-off first, then a gauge "snubber", then the line run into the cab to the gauge.

Without the snubber, the needle will constantly bounce with the pump pulses and, besides being hard to read, will soon beat itself to death.

The ball cut-off valve is to shut off fuel flow, in the event that something comes un-glued.

For a stock-type diaphragm-pump, a 0-16 PSI gauge is ideal.

For the correct 3936320 piston-type pump, a 0-30 gauge is best.

Any pressure gauge will work; it need not specifically say FUEL on the gauge-face.

The one in my truck says WATER.

 

i run the tapped banjo then the needle valve just barely open then the line to the mechanical isspro gauge

 

I want to get a big line kit for my dodge, which one do I need??? Will the 2nd gen 24v universal kit from Vulcan work??? Also what fittings do I need for a "big line" from the piston pump to the filter???

thanks

 

BC847 did a writeup 3/8" Big line from tank to lift pump in the Sticky

 

Yes. The ports in the filter head and the pump are M10 x 1.5 if you want to buy fittings separately instead of a kit.Wrong info - they are M12 x 1.5.

 

I thought they were M12 X 1.5???

 

This is correct.
