Where do you tap into to get an accurate fuel pressure reading with an airdog 150 installed? do i tap the 1/2 hose line of the airdog?

Tap it near the VP44...:w:



The first pics is with a stock fuel system (tapped at the fuel filter output)... The second pic is with a AirDog 150 and big line kit (tapped in-between the VP44 and the filter)... Both time the pressure tap is near the VP44...

Man Mopar Man!
I cant believe you tapped and plumbed your FP gauge with a nylon tubing with desiel going through it instead of a real hose.
That hose can break easy and I know the way you do things to yoru truck your meticulous!

Anyway you have the good Airdog 150 nFP setup now so that dont matter!
:thud:

That tubing is rated for 150 PSI... I doubt a mear 15 PSI is going to blow it out... Not to mention it been in the truck for 4 year and never had a issue. If there was a problem I just shut the fuel down at the needle valve... So there is no real problem... Then go back to AutoZone and pickup another kit for $10 bucks... Boy that really hurt don't it...:T::rof

Get a push-Lok tee if you can, it will intall and seal nicer.

Let us know if we can help in any way:thumbsup

That's what I've got in the line is a push-loc tee... It was the old school way of the Vulcan Big line kit..

The steel tee was so I could have a low pressure light and a gauge...

that goes at the end of the feed hose between the pushlock 90 and the 8an to banjo adapter that comes with the air dog.

i can get pics if you need me to.

I went with the sensor in the fuel outlet side of the pump, The sensor is from the Juice kit, I just extended the wire harness.

thats the other way to do it, i just wanted to get a pressure reading from as close to the injection pump as possible.

On an Airdog, the pressure is not going to be any different from the pump to the injection pump, especially with all the air and water removed from the system and a 1/2 fuel line.

The one good thing I've found with the sensor in the pump is, when I get around an 1/8 of a tank, I can see the pump lose pressure, down to about 7-9 PSI as the fuel moves away from the draw straw under braking. I think it's a safety for NOT running out of fuel :thumbsup

also i dont know why i just saw this but for the gauge i bought (fuell sweep electrical 100psi) it says i need..

"If using on ‘98-’02 (some ‘03) Cummins diesels, you MUST use #3227 Line Kit and #3279 restrictor to prevent premature failure of sender. Failure to do so will void warranty."

are they really a huge necessity? or not?

I was told if i bought a 100psi i wouldnt need a snubber. and why does a electric gauge need a braided steel hose?

this is what you want for the airdog 150, its what i used, and works perfectly, connects between the feed line and the adapter airdog sent for the vp44



Earl's Performance 100200ERL - Earl's Performance Pressure Gauge Adapters - summitracing.com

the earl's one is $23

summit has 2 other, russel's, but i got mine locally, the russels ones are $13 and $14
heres the search results
Pressure Gauge Adapters - summitracing.com
if it doesnt work, its -8 male to -8 female with 1/8" pressure port
will this also work on th 100 model
