Airdog

I put an air dog lift pump in my 2015 f350 yesterday and it ran fine for a few minutes then came up as a fault low fuel pressure. Now the truck will not start. I checked everything there are no leaks but the truck seems dry when I try to start it. I did the whole cycle it 6 or seven times to prime it. I even left it in the on position for 15 minutes still no juice any help would be appreciated

Setting the key to the On position will only run the OEM fuel pump 30 seconds....after that it shuts off. You need to cycle the key Off then to On to get the OEM pump to run again....but only for 30 seconds.


Can you tell if the AirDog is running with the key cycled to On during that 30 seconds??

Ya the air dog is running and I've done the 30 second cycle a bunch of times so many times I'm charging my batteries right now air dog turns on runs good is primed as far as I can tell. After the pumps is done priming after thirty seconds there is a winning noise coming from the engine bay that doesn't stop as long as the key is on. Is it possible to get air in the high pressure side on a 6.7?

I don't think so without the motor running. Just cycling the key should be just the OEM and now Airdog running not the HPFP.


Did you install fresh OEM fuel filters at the same time??

Airdog is most likely vapor locked. Pull the filters off and fill them with fuel. Make sure never to run the tank below 1/4 otherwise you’ll suck air.

I truly don’t understand why people want airdog or fass pumps on these 6.7s. The 6.7 fuel pump supply’s more than enough fuel and the filters are killer effective. We run stock low pressure pumps on trucks with dual fueler kits.

First thoughts are the added filter capability. Second thoughts are they want to remove the lower OEM pump for some reason.



Some people just read too many magazines without thinking thru the modification making a better plan. Nothing wrong with running a low pressure AD to feed the OEM pump.

I like the AD pump/filter on any common rail engine as any air whatsoever isn't good on any fuel system, especially any common rail engine.

The filters need to be filled up before install. I would bet that if you remove the filters there is no fuel in them. Watch Thoroughbred diesel's video on an AD or FASS filter change and it explains why you are having this issue. One thing that helps is that you top off your fuel tank so it doesn't take near as long to prime the AD/FASS type fuel pump setup.

I do agree the 6.7 factory pump is typically more than ample to supply.
