2nd Gen Non-Engine/Transmission How to install Fuel Pressure Gauge??

[JL penner]

Okay, I need help!! I'm trying to figure out the best way to install all my gauges. I have the boost gauge figured out and I have a separate thread out for the pyro. Now, how in the heck do I install the fuel pressure gauge. I have the DiPricol 0-30 psi mechanical gauge. Do I need an isolator for this? It did not come with any instructions on how to install. Where's the best place to tap into the low pressure line? I know to go post filter, but where exactly I'm not so sure. If I don't use an isolator do I prime the line with fuel? If I do use an isolator, what's the best fluid to use? Also where's the best place to go through the fire wall.

Thanks in advance!!

I'm no fan of isolators.



followed some advice of some on this board and went with straight stainless braided line (Ace hardware npt 5' refrigator water hose) for under $20.



took out the schrader valve at the VP44 and used a little 1/8" npt brass valve. This allows you to cut off fuel if there is ever a leak. Plus you run it barely cracked open to limit pulsing. like 1/32 of a turn. barely cracked open. Extremely low volume every gets to cab.



had a leak once at vp44. only a few drops, but smelled it. diesel is very pungent, and just turned of needle valve until I got it repaired.



I also put the stainless line inside some split loom wiring harness to keep it from abraiding anything/everything it touches. also recommended on this board.



very happy with installation. Oo. Oo.

Did mine real similar to RobertMiller.



I ran 1/8" tubing inside of some larger rubber vacuum line to protect the smaller tubing. I had about $5 into the tubing. I also used a needle valve to isolate the line. I have a tapped banjo bolt on the VP44 inlet so I threaded my 1/8" grease gun hose on there, valve after that and then the sleeved 1/8" line into the cab.



I don't have an isolator and I have seen a few fail. I had an electrical gauge and when I went mechanical I decided to make it as simple as possible.



I also didn't bleed air out of the guage tubing. Well, once I did. But I have played with that setup about 4 times and the other three times I just hooked it up and went. The air will find its own way out quickly.

I went through the firewall at one of the rubber grommet/seals. I used a coat hanger to guide it through, ran under the dash, up the side of the dash and into the a-pillar. I check often for leaks and have never had any.

I went with the isolater. I smoke and didnt want fuel in the cab. I ran a line from the new bango I got with the isolater on the out bound side of the filter housing. Found a place to mount the isolater its up to you where ever you want. Then threw the fire wall at a rubber grimet. and to the guadge it was the easiest of the three guadges for me. For fluid in the isolater I used antyfreez, regular fifty fifty mix. Good luck Doug.

Ordered a 18" fuel hose from Genos, I'm just going to hook up to the shrader valve off of the VP44.
