Wheres all the how to threads. FP guage install?
 

Yeah I had these guages for awhile now. Finally getting around to installing my aftermarket parts. Would like to look at some how to thread espeically on hooking up the FP guage to the fuel line.

Do you have to bleed the line at the guage? just wondering because I'm mounting the gauage in a pillar mount and once installed it will be kinda hard to get to do so once its in the truck. advice needed.

Yes if it is the type that has fluid into the gauge it will need to have air bled out. It is better to run a snubber and have different fluid running to the pillar. Or using and electric fuel gauge

whats that? an isolator ? I am fairly new to the diesel world so still have alot to learn, but by no means am I a rookie on the wrenches.

I can say this, what I am planning on doing because I have heard alot about running fuel into the cab. So what I am thinking about doing is run my supply line to the guage. Then take a larger line over the S.L. and put a clamp on it over the guage fitting, so If the line ever did decide to leak, it will be rerouted back outside thru the larger line.

Gino's makes a fuel filter cap with an 1/8" threaded port on it and you can put a sensor right on the cap. No banjo bolts to mess with.

ur going through what i did. just put in my gauges a week ago. PM me if you like and I will send you my # and we can chat. way too much for me to type. i also have a 2001.

But, it benefits many more people if it's explained here.

appreciate the offer. maybe you can post up some pics of what you did on here. benefit others as well. I should do that myself when i get back to working on my truck.

I can Wednesday

Thatll be great. Fortunately mine isn't a DD so I can work on it some and leave it apart until I can get back to it.

Barry sorry I ran out of light tonight. I will take video of my whole setup so you guys can see what I ran. I had to get my new fuel pump installed tonight. Boy was that fun. Spilled so much diesel on my lawn. Sigh.


Anywho these are the parts I ordered.

Basic writeup:

Autometer Gauge I run: Auto Meter 6963 Cobalt Digital Fuel Pressure Gauge

I tried GlowShift and went through two sending units in two weeks before I demanded my money back. Even if they ship you a faulty unit, they tell you they cant issue a refund, only constantly replace parts. Buyer beware.

1. Remote mount your sending unit. The vibrations from the engine will kill it. All GOOD gauge manufactures tell you this. Glowshift is CRAP and their instructions do not, however, if you call them they will say "the instructions are generic. even though we tell you to mount it to the bottom of the fuel filter housing, you should remote mount it."

But what parts do I need? These are the parts I HAVE on my truck and run just fine.

Banjo Snubber (I am a 2001):
Cummins banjo snubber for '98.5-'09 Turbo Diesel trucks.-Geno's Garage

Grease gun extension:

Stainless Steel bushing:



Order of operations of the above:
---use diesel safe thread sealer----
A) Screw the grease gun extension into the 1/8NPT end of the banjo snubber.
B) Unscrew the factory banjo bolt on the bottom of your fuel filter housing (some models are on top of the fuel filter housing)
C) Replace the two washers that are on the banjo bolt (about 4 bux a piece at dodge)
D) Re-install the banjo bolt


2. Screw your the stainless steel bushing onto the 1/8NPT end of the grease gun extension

3. Screw your sending until into the bushing




If you want to make all your wiring look pretty buy this:




I zip tied my sending unit to a big wiring loom right below the oil dip stick. You will see it in the video when I post it. I ran my wires up through a hole in the firewall and up my A pillar to my gauges. I used the battery for ground and loomed the wire against the driver's side fender so it isn't in the way.

Thanks guys. SO basically what I take from all this is If I get my fuel line tapped somewhere. preferably close to the IP I can directly screw in the sending unit with the correct fittings, and then wires up to the guages. So I don't need a isolator, I believe I am going to just try to sell my mechanical isspro fuel pressure guage and get an electric guage.

Yea you can go that route if you want. The rubber fuel line between the IP and bottom of the fuel filter housing acts as a buffer for vibration. Not as much as an 18" grease gun hose though.

My truck will have the airdog setup when I get all this hooked up. So I'm thinking T into the fuel line run another piece of fuel line up and out of the way. Then hook all the sending unit up and such.
All this info is much appreciated.

Airdog has a built in port for a sending unit

Yeah I was aware of that, but I'm thinking the closer I get a reading to the IP the better I should be able to monitor my Fuel P. Thats my thought or am I just over thinking it?

ur right generally u want to measure closer. after my raptor failed after a week i wouldn't monitor pressure at the pump personally. glad i wasnt. i monitor after the fuel filter so i can tell when it is getting clogged and its time to change it.

Thats what I was thinking also.
