So I put that airdog 150 on my truck, and , one morning it would not start, zero fuel pressure from the gauge. After troubleshooting the  obvious suspects, I took a rubber mallet and started tapping on the air dog pump itself. The air dog came to life and the truck started as normal and ran great the rest of the day. Next few days same thing, I always had to take rubber mallet while somebody else was turning over the truck and it would finally start. So I called air dong and told him I have a bad pump, and they said take the gears out the side and soak them in motor all overnight. I have not done that yet? Is it a waste of time or has anyone else had this problem before?

That's not going to do anything... :think:

 

Steel is not going to soak up oil. Then not to mention the diesel fuel will wash it off the first second the pump runs. It sounds like there is a bad brush or armature problem when your beating on the pump electrical connection is made and the pump runs again.

Another reason I will never buy another airdog again

 My old AD pump just quit a few weeks back and after explaining the trouble shooting I had done they just asked me where to send the new pump. This sounds like someone just getting you off the phone. Pretty poor.

I was using China in place of a #%¥£€=*%% word lol. I’ll be getting an airdog next go round.

My replacement was a 4g. It is a little longer than the old. I had move the mounting braket about 3/4" to rear to fit.

I like how the new 4G's are put together with a love joy coupling instead of directly to the pump. Going to be my next lift pump.

I've had so much bad luck with electric pumps...with a few Carters and a few Raptors (never tried Air Dog or Fass).  I gave up on electric and went straight mechanical with the belt drive.  I've had great luck since...with fuel pumps anyways.  Very consistent fuel pressure (15 idle) and increases with throttle (19 wot).  It's a pretty cool system.

Your problem is you always used a non-returning pump. Raptors and carters are known for those problems. No returning pumps like AirDog and FASS typically don't have this issue because the pump is no constantly deadheading. Even though the Raptor's and Carter's had a return system internal this just create cavitation issues still promoted pump wear.

I went with a Fuel Boss...couldn't hardly find any bad press about it.  Everyone that had one spoke well of it...I see why now.

I heard that alot during my problems with the other pumps...'should've got a Fass or Air Dog'.  And I probably should have initially but the mechanical pumps had been out in the market for a while and getting really good reviews and comments so I went that route.  It's been blissful so far and I do request more out of my vp44 than many do.

The only instability I've got currently is my mistake. I bent my spring the wrong way and got a high point in the center which causes the check ball to float off to one side so sometimes my pressure will drop and hang low till the check ball gets back to center again.  That the only problem currently I've had. Past issue was pump head failed after 13 years of service. 

 

I've got a Raptor sitting in the shop on the shelf with a blown shaft bearing and shaft seal. Raptor's for some reason have a shaft seal so hard it cuts the motor shaft causing the fuel to leak into the shaft bearing which now washes out the bearing till it fails. I quit recommending Raptor pump long ago after seeing the 3 local ranchers lose pumps. Then went to suggesting AirDog and FASS. The only problem I've had with FASS 150 pump is the filters hanging in the damage path problem either the filter strikes the ground or ground debris (or log) in offroad use or the filter are exposed to extreme cold and gelling fuel problem are more common. I've seen FASS filter encased in snow and ice from the front tires flinging the ice for miles.

My 4g is working fine. Still strange not hear it run. I would not know it runs if not for the FP gauge.

Same with mine. Dead silent operation. 

The silence is strange. Not that the old was loud but you coild hear it until the Cummins drowned it out.
