Engine/Transmission (1998.5 - 2002) To all who will help!!!!

[Smokin Joes 2500]

Well you've got me convinced I want a fuel pressure set up now. Where do I tap in for the fuel pressure? What should I expect it to read at. What gauge should I get 0-15 psi or 0-100 psi ??? Love you guys thanks for the help... ... ... ...

First do a search for pressure gauge... you will find a whole bunch of info... you have several options. . the easiest is to get geno's tapped banjo bolt and that is pretty much it... as far as what to look for... there is still many debates and questions about that. . the latest is looking for positive pressure... . but IMO

No more than 22psi

No less than 10psi at Idle

No less than 6-8psi WOT

I tapped in at the injector pump where the lift pump feeds it. Use new banjo bolt from Genos and use a grease gun line to the pressure guage. I got my 15# guage from Genos I think. Dont get a 100# since the injector pump will not like anymore than 22# anyway.

I JUST DID MY FP GAUGE. I USED THE WESTACH 30PSI GAUGE AND TwO SENDING UNITS ONE TAPPED OFF THE SIDE OF THE FILTER WITH GENO'S BANJO BOLT AND GREASE GUN HOSE AND ONE OFF THE BOTTOM OF THE FILTER HOUSING WITH THE SAME SET UP THEN I PUT A SWITCH TO SEE BEFORE AND AFTER FILTER

Oo. Oo. Oo.

Mine: WestTach 0-16psi fuel pressure gauge with the sending unit attached to Briar Hoppers A/C charge test hose. This way I can always have the option of switching to the mechanical gauge if my WestTach gauge shows something that I need to confirm.

Because of the pressure that our trucks run you would be best off with a 0-30 psi guage.



Guages are designed to operate best in thier mid range so a 0-30 works best in the 12-18 range.



Good luck and have fun.

grease gun hose???

What do you guys mean a grease gun hose? My grease gun hose is full of... ... . well grease! Do I have to prime the system or anything like that after words. I was thinking of using the AutoMeter braided stainless line to the gauge.

 

[msperos]

The tapped banjo bolt and sending unit are both 1/8" fpt same as a grease gun hose. they are very strong and a lot cheaper than other lines. got mine from grainger about 7 bucks on my setup I am using a westach electric gauge. I did not want to pipe fuel into my cab and for the price of an additional sending unit and switch i can use one gauge to check fp before and after filter. Also i did not bleed my lines and from what i have read most do not.

I would recomend at least a 0-30 psi gauge or even a 0-60 psi.

I see 33 psi at idle, and 14 psi wot. Installation the simplest way is to use the connection fitting off a standard mechanical gauge. This ties into what looks like a bicycle tire fitting. It is located directy in the fuel supply line pre-vp44. Simply hook you sending unit offf your new fuel gauge into the hose from the machanical gauge - done no tapping easy to remove if wanted.

fuel pressure

Isspro mechanical EV series S/S braided line 0-30 psi

in cab works reaally goood. Oo.

Enterprise Engine and Black Mountain diesel have mechanical fuel pressure gauges that read to 30psi.



You definitely want a mechanical gauge. Simpler, more reliable.



On the '02s, it's an easy setup. Go to NAPA and get a -4AN to 1/8NPT adapter, screw than into the Schrader (tire valve lookalike-- remove the valve core) just before the pump. Then screw grease gun hose into this, run it to an isolator, then run isolator line to the gauge.



The Enterprise setup uses Hewitt gauges, and the back of the gauge is 1/8NPT-- makes the install a snap.

Setup #1 - Check fuel pressure and disconnect.



Best bet is enterprize engine or black Mountain diesel's gage. All set up and ready to go.



Setup #2 - You want constant monitoring.



Since you have an '02, I do not believe that you have the tow nice tapped outlets on the filter canister. Geno's sels a tapped banjo bolt that you can put in the inlet to the canister. It is tapped for the sender. I would suggest an electrical gage and sender. This way you do not run the risk of a fuel leak from a cracked / broken / disconnected hose and possible getting fuel in the cab. if that's where you put the gage.



Just my opinion, but, I would prefer a 20 PSI gage, I believe that Westach will make you whatever you want. The upcharge is not that bad. The tighter the range the more accurate your reading.



When making changes to your fuel system, be careful. The VP44 does not like too much pressure at startup.
