Engine/Transmission (1998.5 - 2002) What is the best way to test fuel pressure?

[Chace TX]

I have a 2001 and have installed the the 1/8" npt tapped banjo bolts pre and post filter. I have ordered a Dakota Digital gauge, and it is not here yet. I want to get a manual gauge for testing and be rigged up to test from Schrader valves as well as the 1/8" npt fittings. Also what do I need to test a 98. 5, they have 1/8"npt fittings on the filter housing don't they? Where can I get in contact with Briar Hopper?

Andy at: www.smokindiesel.com has a really nice test gauge setup with a long hose that allows you to have the gauge up by the windshield too so you can do a road test.

With my trusty Briar Hopper's gauge.



Ranks right up there with my Cup Smoothie as one of my favorite "must have products".

with the black mountain setup, do you get all the fittings to attach it and is a permanent mount or just a temp one?

You tell him what year truck and he'll supply the appropriate fitting on the hose for you to plug 'n play. It's a temporary/quick-n-dirty way to check your FP, also a back up to confirm the reading of your permanent gauge if/when you get one.



Instructions that come with it are complete and idiot-proof. Everyone on here who's ordered one highly recommends. Cheap insurance.

Installed a Geno's Special

I just installed a Sender and Gage in the front of the Cab in My 99 . It looks good and works great. I put the sender on the top of the fuel Filter assembly. I chose the output of the Filter or the input of the VP44 Pump. It measured 13 lbs at Idle 10 lbs at 60 mph 9 lbs at 70. and about 7lbs at 90 . It's attractive in the Dash. took me most of the day but really wans't hard . It was about 95 in mt Garage and i took lots of Ice Tea Breaks ha Good Luck Bill.

Is it just me

I have Brair's gauge and tried it out last week on the 2002 HO. I found due to the slope of the windshield it is hard to see the exact reading of the gauge unless you lean forward and pratically have your face up against the window. I tried taping it at various heights and positions with no better luck. I think the gauge needs to be positioned so its off the windshield and in more of an upright position to allow you to be able to look "straight-on" at it and get an accurate reading of exactly where the needle is. What I was finding is when sitting in a normal driving position I would be viewing the gauge at such an angle it was hard to tell exactly what number the needle was pointing at (an exaple may be it looked like it read 12 or 13 psi, but when I leaned forward and got really close to the windshield and looked at the gauge straight-on it was reading say 10 psi). Maybe I'm just retarded , but this having to lean way forward to get a good view of the gauge in order to get an exact reading makes for nerve-racking WOT tests. Due to this I was only able to get an approx WOT test reading I could tell the needle would go down to somewhere between 5 and 10 PSI on the gauge then rebound to around 10 psi after 1-2 seconds. It was difficult to keep one eye on the road, one on the gauge, speedometer and RPM Plus it didn't help that traffic at the time was moderatly heavy and I was comeing up on a road working construction zone really fast



I think if the hose on the was 2 ft longer I could just leave the drivers side window down and hold the gauge. It would make see the readings easier IMO. I'll try and find a lonely stretch of road this weekend and give it another shot. If I don't have worry about rear ending someone at WOT I can concentrate more on tring to read the gauge.

Does anyone make a fuel pressure gauge with a longer hose or an extension hose for a fuel pressure gauge. Thanks.

Have someone else drive, you sit on the hood and hold the gage... :--)







OK, bad idea. I've used two different methods with Briar's gage; both worked:

1) Use duct tape to "pull" the gage away from the windshield and hold it at a good viewing angle. Just imagine a tent guy wire...

2) Stand beside truck and hold gage while someone else runs up the rpms. I know "loaded" WOT is the greatest challenge, but I read somewhere on TDR that DC defines the specs based on 8 PSI, unloaded WOT. If your lift pump is going or gone, you don't have to load it going up a hill to see the low, zero, or even negative pressures.

I mounted my Briar Hopper Gauge in a block of 6" square styrofoam. I run the hose under the windshield wiper and duct tape the foam box to the windshield where I can see it real well. Looks weird but works great and protects the gauge.

got a question guys, I had a 95 now I have a 99, just got it a week ago so all this lift pump business is new to me, with my 95 I was worrying about the KDP, now I have to worry about lift the pump! Anyway I've got this expensive liquid filled mechanical guage from a piece of equipment here at work, for a temporary check can I hook it up with a grease gun hose under hood and check the psi? Anything I need to know before I do this? And what psi should I see? I still have some of the factory warranty left, if the pump is bad will DC replace it? Sorry for so many questions but I'm learning, Thanks, Chris.
