I'm trying to decide between an airdog 150 or the airdogII. I know the 150 will supply more fuel than I'll need, but they are set at 15psi and I would like to be able to adjust it. 15psi is good, but is it best? I would like to see 16 to 18. Any input would be great.

There is a second spring included that jacks it up to 17-19 PSI... Or like I did I used a shim washer on the spring and adjsted it to 17 PSI... As a matter of fact it time to do some maintenance on my AD150...

That is good to hear. Save $100 or so.

I shimmed mine too but I'm getting 21psi now. I suppose i should take one shim out or what's the upper psi limit for the vp44?

20 PSI is the undocumented high limit.

I'm more than happy with my Airdog 150 for fuel filtering and flow. I can't run the 2 micron filter in the winter though. Even with winter fuel addatives, the gelling fuel will clog the 2 micron filter. The 10 micron filter seems to do fine in the cold so far (to -25F). I do wish I had mounted mine like Mopar Man - in between the frame rails just behind the transfer case. He may have pictures or a technical drawing of his fabricated mount (hint hint). Just my 2 cents.

Hint hint...

As for filter I've been down to -25*F with 2 micron and still no issues with gelling or plugging...

Thanks for the photos. :thumb1:Is that just a slab of steel with a 90 degree bend? It looks like you bolted it to the Airdog mount and sandwiched it between the frame and the frame clamp. Am I right?

Correct this is a old school Airdog Short Box bracket which is no longer produced. I'm hoping my conversation with AirDog will bring that into production... (wishful thinking)
