My fuel pressure kept going up and down.  The adjustment "jam" nut (9/16) I can turn but the nut behind it (3/4") also moves.  Can't get wrench on it because of bracket is blocking wrenching room.  I ground down an old wrench, still not enough room for both wrenches. Problem is created because I turned the airdog 180 so I could use old fass bracket without drilling new/more holes. 

 

Question...if I hang pump on fence and suck fuel out of bucket to set pressure will pressure be the same when hooked up to vp44?  

Thought I would bend over vinyl hose to create back pressure.  

 

I don't want to keep taking pump off and on...thought hanging on fence to adjust would be easier. And only have to set one time. Dreaming or good idea?

Thanks

 

(Edit... pump on fence tottaly independent of vp44)

Call AD They will send you a new one Dave. Make sure you have the type relay that also protects the ECM since at this point the Air Dog could place excess load on the ECM.

The pump I blew happened 3 years ago or so. I just popped a fuse today. They replaced that with very few questions asked. 

The pressure was a little wonky when I replaced the fuse but settled in after about 20 seconds and all is good so far. I will have to keep an eye on it. If this goes the warranty still better cover it. As far as the relay goes, I will check that out tomorrow. Too many things to remember sometimes.

Having F/P problems with one of my 2nd gens, AD and me thought there was a regulator problem with the new 150 I got from Vulcan. They sent me another 150 with the agreement that I would  send the other back to them. They wanted it for testing to see what went wrong.

 

When I found out my problem was (still is) air building up over the top of the prefilter playing havoc with the gauge. I then called AD asking them if I can pay for the extra new 150 they sent me and not send it back since my other truck's AD 100 is getting tired. They were so nice.... said if you have another truck with another AD they said just keep it for when you'll need it. They were so nice to me.

I am with you on that. When mine blew the only reason they asked as many questions as they did was because all the info I needed to answer them was 200 miles away. All in all it was a very good customer service experience.

They seem to understand what its like for us hard working truckers. Smaller truckers, that is anyway.
