6.4 lift pump and AD2 165 success!!!

Ok this took a while because I have been very busy! But I have success and I am very happy with outcome.

first off in prior posts I was asking for amp reading for a reason one to help identify what was going on with them and also to rule out 10 gauge wire need! If you run it by itself then yes I think the 10 gauge wire is a good idea,but if you do this there is no need. I was recording 6 to 7 amps with my airdog 2 by itself and with the 6.4l pump in front of it I recorded 2 to 3 amps tonight and pump was audibly much quitter. I also was running at 60 psi and after I installed the 6.4l lift pump the pressure increased to 80 as you will see in photos I had to back pressure regulator screw out almost 1/4 of a inch to get it back to 60 psi,i was amazed!!! Rich and I already identified the problem with the pumps being the shaft seal and purflow promptly said they where a problem and offered new pumps. I received my new one but elected not to install it yet as the needle is perfectly still now so now on to what I did.

1) Took the factory plug and cut it in half I added 4 feet of 10g wire with 4 wires 2 for WIF and 2 for pump. I also made a leg off the power wire for airdog 2 relay wire!

2) lilpooh (Rich) fabricated a bracket 5 inches high and 7 inches wide to fit 6.4l lift pump

3) The return I decided to use the factory suction line this is the 5/8 line on top of tank because the other line is 1/4 inch and that is not large enough. I dropped tank and bent this line with bending tool to rear of tank after removing suction screen. This will vent any air that is in the fuel to rear of tank and not directly down at sump!

3) Measured lines and installed like this,from sump to 6.4l inlet, from 6.4l outlet to airdog2 inlet, from airdog2 outlet to 6.4l return inlet, then from 6.4l oulet to 3/8 nipple on top of tank capping off 1/4 with plug.













THIS IS WHAT IT JUMPED TO WHEN I FIRST STARTED IT! THE 6.4L PUMP IS ONLY 8 PSI BUT HIGH VOLUME. THE AIRDOG2 REALLY LIKED NOT HAVEING TO LOOK FOR FUEL. I HAD TO TURN IT WAY DOWN THATS WHEN MY AMPS DROPPED TO 3 AMPS.




I hope you guys liked this!! I had fun doing it!

I don't care if this sounds stupid or not: where is your 6.0 pump? Further, I'm waiting on FedEx for a 6.0 HFCM, should I return it for a 6.4 pump?

My only fuel system mod is a blue spring.

Thanks for sharing. It's cool seeing different ideas.

No question is stupid my friend, I don't have a 6.0l pump I replaced it with the airdog2. DONT run just a 6.4l pump alone as it only makes 8 psi. The 6.4l pump is high volume low pressure pump because it feeds a common rail system.

Makes sense. Kinda glad, I didn't want to wait another 10~15 days on back and forth shipping to change my fuel pump.

So Dale, you're using the 6.4 pump to feed the Airdog?? What's the big clear tubing there for? I have that for fueling my second fuel tank.

IIRC, his clear line is for the CCV mod.
