Set it up, check it with the truck running, reset it higher/lower if needed. Mine comes out at 21psi pretty much all day long. The pressure shouldn't really drop there even at WOT since the Walbro is putting out much more pressure than you are using. Also check out the wiring to the Walbro and make sure it is getting all the juice it needs. Try disconnecting the fuel line after the pump and crank the engine and watch the fuel shoot into a pail or something. Here's a pic or two of my setup:

I use it and mounted just off the battery box which has a small tab to bolt to next to the IP. I run 2 systems (veggie and diesel) with FASS on the veggie and Aeromotive on the diesel side and keeps it right at 15 psi. It has an adjustment *** on top that utilizes an Allen wrench and real easy to adjust. It does have a return line that you can Y-Block back to the return. It will keep it very steady at 15 psi which I set or was my goal.

However, I am not a big fan of the Walbro as I went through a few of them on the diesel side. I settled for an aeromotive AEI-11203 which has appx 60K miles on it. The Walbros where crashing after 30K. If the Aeromotive goies out, I'll switch to the nes FASS replacement pump. It is also relocated to the frame rail with Geno's relocation kit. But the new FASS will bolt as a replacement on the engine. Save the headache and relocate the pump at the frame rail which will be less vibration and heat saving a longer life for your LP.
