Fuel Pressure gauge help needed...

[mconstable]

I'm running an Airdog setup, and was curious if anyone is running one, or a FASS, how did you hook a fp gauge?

Thanks!

I run a FASS and I put a "T" in the fuel line right before the CP3 pump. I attached the sender to a Westec fp gauge off the "T".

I'd suggest Kompressor's solution. Very simple.

The more "industrial" filter heads have multiple in/out ports which allow you to connect gauges or route fuel around to multiple locations, so those of you considering Airdog or FASS might also consider offerings from others like Stanadyne or Racor.

I run a FASS and I used a tapped banjo bolt on the bottom of the stock filter housing with a grease gun hose to a Westach FP sender.

Exactly, a sender after the last filter and before the CP3 is what you want.

When I added a 2 micron filter and head after the stock filter it had an extra "out" port and the grease gun hose/sending unit were installed there which made it simple. I don't know if the grease gun hose is as needed in the 3rd gen trucks as it was on the 2nd gen trucks but I figure it would simply help with engine vibrations. Thoughts?

Godspeed,

I have mine in the hose so it doesn't see vibrations from the engine. In general I think that's a good thing. The 2nd gen trucks need a needle valve more than the rubber line as the VP44 "Hammers" the fuel and that kills senders, the CP3 doesn't do that, so just a hose is plenty.

I used a tapped banjo bolt on the Cp3 inlet fitting with a hose from Geno's to the sender. I had a few of the Westec senders fail, they all started to leak fuel. Ended up going with a mecanical gauge from Isophro (sp?) but you need to use a needel valve inline to remove the pump virbrations or it will kill the gauge and anoy the hell out of ya.

get the taped banjo bolt and a fuel pressure snubber part # AM-3279 from genosgarage.com. get a oil pressure gauge installation kit from auto zone for about $7 i use the copper ones but some like the plastic lines. get the gauge from ww granger. i like the glycerine filled ones. they are about $12 you now have the best for less than $60

While they may be a little pickier, I am quite happy with my electric sender, despite the cost. I would rather have no gauge, than running fuel or coolant into the cab.

most equipment and big rigs have run fuel to gages for over 75 years. only the newer ecm has electrical. and when the #4 injector line breaks and sprays two gallons on the hot engine and does not start a fire, i consider it safe. the electric must have the snubber. the best thing if you go electric is to still use the copper line kit and snubber and mount the sending unit on the firewall near the clutch master cylinder. do not cut any of the 6 foot line off just leave it coiled up. this even works on the quad commander

Safe, and easy to clean are two very separate issues! There is also no requirement for a snubber on a 3rd gen.
