airdog and fuel pressure sensor location

[2001white]

seeing that surging can be an issue would putting my sensor in the air dog sensor hole location be a good idea? or would this be to far back? mine is located under the drivers door on the frame.

This is fine. Just install the snubber at the AirDog and the run 5 foot of air brake tubing up from there and remote mount the sensor up under the hood. The length of tubing allows for the remaining pulses to fade out in travel.

Is that "airdog sencor hole" post filter or pre filter?

 

(Testing with manual gauge at airdog  and elec gauge in cab.

 I get about 2 pounds difference between testing at airdog and at vp44.  Not sure if gauges at 100% percent accurate or pressure drop between the gauges or if airdog test port is pre or post filter.)

I'm pretty sure is post filter... Being the flow map is...

 

Inlet -> Water separator -> Pump -> Fuel Filter -> Outlet

                                                                           -> Return to tank

I have my gauge on a snubbed right at the injection pump. I've got a live pressure gauge plumbed ti the cab. Many dont like fuel running to cab. I've had no issues with this setup for along time. 8 years or so. 

 

I'm running big line from the tank to pump through factory filter.

 

MoparMans way probably is the best but this works to.

I have run the same set up 8 or 9 years myself. Different gauge though.

That's a gauge out of a fuel tester kit I bought when I was trying to figure out why my 2001 expedition had no fuel pressure. 

That turned out to be the anti theft system was enabled. And had to be reprogrammed.  That's one vehicle I wish I never bought.
