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...
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::rofMan 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!
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..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
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.thats the other way to do it, i just wanted to get a pressure reading from as close to the injection pump as possible.
yeah it does the same at the vp also, you know its time to fill up when it hits low numbers lolOn 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
will this also work on th 100 modelthis 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
