Fuel pressure gauge install pics

[JStieger]

Please check out my reader's rig gallery for pictures of the fuel pressure gauge install I did on my truck this past week. I trieed to explain everything the best I could. Hope they help someone out as lots of your truck pictures have helped me a lot in the past.



If anyone's interested I can post later all part's numbers I used.



If I didn't get side-tracked with filling the 1/8" isolator tube with antifreeze, the whole install would have taken about 3-4 hours. Did lots of the pre-install on my kitchen counter while watching TV! Permatex #2 was used on all NPT fittings per a TDR search.

NIce install, where did you get all the parts?

Great looking install. By the way, is that a stock fog light switch just to the left of the steering wheel, or is it aftermarket. I'm looking for one just like that.



Thanks,

Malibu -



Here's the major parts list:



*Geno's - tapped banjo bolt and washers - (#BF-KIT-32: comes with 2 tapped bolts, 1 regular bolt, 10 washers, but only used 1 bolt and 2 washers)

*Geno's - Di-pricol gauge w/ isolator, nylon tubing, compression fittings, and 1/4"NPT to 1/8"NPT bushings - (#DI-FPG-30)

*Geno's - steering pod mount - (#GM-DG-1501)

*Summit Racing - Autometer 4' braided 4AN tubing kit - (#ATM-3229: comes with 4AN tubing plus adapters to NPT - in hindsight I should have used 3' kit)

*Summit Racing - Aeroquip 4AN male to 1/8" MPT 45-degree elbow (#AER-FBM2582)

*Carquest - 1/8" MPT to 1/8" compression fittings (2 @ straight for "just-in- case" & 1 @ 90-degrees for hood clearance)

*Carquest - 6' of 3/16" windshield washer tubing

*McMaster - 1/8" needle valve, 1 end female other end male - (#7833K83: you can get brass ones from a well equipped hardware store for about $5, but could not find any locally after searching for a few days so I ordered this $19 steel valve)



Good luck!

DieselMinded-



It threw me for a loop too at first when I read people's posts, but this is what it says on the tube:



"Permatex 2 Form A Gasket Sealant"



I purchased it at Checker/Autozone.

Thank!!! I love this site.

Vic-



Thanks! The switch is not stock. I ordered the '03 Mopar fog light kit and it came with this switch, relay, harness, and lights. Soon after I did this, another TDR member posted that he bought the factory '03 headlight switch with foglight capability. Since my truck and other '03 without the actual foglights still came with the harness to the bumper, he was also then able to source out the lights to complete the install. So, in short, I now have 2 foglight harnesses: the factory one and the Mopar aftermarket one. I believe that the other TDR member was DJacques (sp?).

 

[DieselMinded]

Thanks for the details.



I found it finally



HERE



Slow drying, non-hardening sealant designed for sealing cut gaskets and stamped parts. Allows for easy disassembly if required. Temperature range -65°F to 400°F; resists common shop fluids and fuels. Use where sealing is more important than adhesion.



Suggested Applications: Valve cover gaskets, oil pan gasket



I hope 1. 5 oz is enough ... . I usually get carried away with this kind of stuff .



Thanks again

Nice install!... ..... 6~7 PSI at idle? I'd be looking at a new filter.

 

[bpenrod]

How is the isolator in relation to the guage? I was going to go that route but read if they are not level with each other the reading can be off. I just used a 35 psi boost guageand plumbed the diesel fuel into it. It could get messy if it ever lets go but from what i have heard the anti-freeze is just as big a mess!

 

[JStieger]

akamac - a new filter is tomorrow's project! I switched the power pup to "extreme" this afternoon and I was able to go down to 2. 5 psi at WOT. The gauge does respond a lot faster on extreme versus the performance program.



bpenrod - I read that too in the 2nd Gen forum. I would say where I mounted the isolator on the flange is about level to 1/2 foot higher than the gauge. This is word-for-word what the Danin / Di Pricol gauge "diaphragm type isolator C160 160" instructions say:



"Install the isolator under the hood at any convenient location. Self tapping screws and regular screws with lock washers are included with the isolator. We recommend using lock-tite on the mounting screws for a more secured installation. The preferred position is horizontal with "Gauge On This Side" connection on the top. Connections on both ends of the isolator are 1/4" NPT.



Fill the isolator with antifreeze. Connect the isolator to the fuel pressure gauge using a Danin tubing kit. As long as the tubing length is 6' or less, you do not need to fill the tubing with antifreeze solution. For longer length, fill the tubing also. Use teflon tape on the threads for a good leak-proof connection.



Using appropriate hardware and preferably braided stainless steel hose, connect the fuel source to the other end of the isolator. Crank the engine and remove the air bubbles from the fuel line by loosening the connection at the isolator. You may also want to do this with the antifreeze line. The few left over bubbles will not affect the performance of the isolator. "



I started the install based on what I read in the 2nd gen forums. 2 hours into filling the darn tube 1/2 way with antifreeze outside in 10-degree weather I decided to read the instructions. By the way, do not use brake cleaner to clean up antifreeze off the gauge pod unless you want to paint it. Don't ask me how I know. That's why my gauge pod looks like gloss black.



What type of pressures are you guys running?

It could get messy if it ever lets go but from what i have heard the anti-freeze is just as big a mess!

Yes, but the anti-freeze is a fixed quantity... just a few ounces. Your fuel pump will empty all 35 gallons of diesel fuel into the cab if you let it.

I'm hoping I catch it before that!!!! And I think the truck shuts of power to the fuel pump in an accident so if that works that would be good!!!! I am seeing around 17 to 18 pounds pressure. It seemed to go up a bit when it got cold so it might be time for a filter change.

 

[SandyHelton]

I get about 7. 5 lbs at idle with the same setup as described here. At WOT it does not drop but a few pounds.

 

[Briman]

I have a Westach electric with no snubber, sender attached to the bottom of the fuel filter canister. I reads 9. 5-10 psi at idle. I can suck it to zero psi with wot and bdpp on performence setting.



I saw others were listing there psi values and thought I'd add mine to the mix as well.

 

[LEPage]

From my experiance, about 9. 5 psi at an idle with a new filter is the best you'll see. DC lift pump function test does not call for a givin pressure, but rather a specific rate of flow. I forget the numbers, but they also claim the CR CTD does not need any lift pump. My experiance also shows this to be wrong, as when my pressure drops to zero my performance does also, even on stock settings, although it has to drop to zero to be noticed. As long as you have any positive pressure, you should be OK.

Great pics jsteiger.

Do you still have pics of this install some place? The lack of instructions that came with the gauge is pretty sad... ...

Sorry... no more pics. I deleted them out of my gallery and then my computer crashed last year. I lost all my saved pictures.
