airdog has to much pressure for a VE pump... hope you have already taken care of this... not sure but i read somewhere you can buy what i would call like a limiter to reduce the line pressure.... check into it..

If you run an AD setup from a second grn the pressure is just fine 15-20 psi and if it's still to much you can get different springs for it to drop it more.

Yep A 2nd gen 24v setup is perfect for our trucks. Even the fittings are correct.

The p-pump set-up has to much pressure.

The guy told me he had one for my 1st gen truck, but I have read on air dog's site that you can adjust the pressure.

Thanks guy's for all the help.

i heard not too long ago that an airdog with an adjustable regulator may have been in the works... i've also read you can get a spring kit that'll adjust pressures... idk what kinda base all of that has... just what i've read
