Finally got around to trying the "high pressure" spring that came with the AD150. It gave me the same pressures as the original spring. So I put the original spring back in and added a .060" thick washer, ID & OD matched to the fitting. Fuel pressure is now 17 at idle, and 15 at WOT.

Nice to be able to shim the spring up with a washer and then get you pressure tuned where you like it... I'm just running a single washer in mine about the same thickness as JL's... Still rock solid 17 PSI at idle and above 15 PSI at WOT runs... :thumbup2:
