Ok. I see you guys say 20-15 psi on fuel pressure is good. I got some gauges and it reads 10psi at idel and 5-6psi WOT. I thought maby I hooked up the gauge wrong and so I did it again and I am sure its right. Now what do I need to do. Truck never studders and starts good hot or cold. Truck runs good really if I did not have gauges I would not be able to tell the difference. I dont want to run the VP low on fuel since that all that lubs it. What should I do?

I talked to an airdog dealer about the raptor 150. They said it would work on stock engines also. What do you guys thing about that. I want the 100 but they got the 150 on stock and ready for me to pick up if I want it. And for only $10 more why not:shrug:.

Think you just answered it Grab the 150 - that way of you EVER decide to add more mods and want more pressure - you have it What they quote you ? Jkidd is a vendor here and can probably get you a airdog for like $475 *guessing* Get the guages tho !!!! Gauge Gauge Gauge *lmao*

well i cannot get the memory of bleeding my airdog out of my head. had the wifey come outside to bump the starter, friend under the truck checking for leaks. fuel came SO FAST that it filled my catch pail, soaked me, covered the front of my truck and ground with probably 2-3 gallons(not counting whats in the bucket)! by that time my friend had his wits back and unpluged the electrical connection under the truck.think about this for a sec. in less time than the pump usually runs, i know i got way more fuel than my VP44 can pump. i can always hear fuel going down the filer neck(witch i wish i wouldn't of cut) and i assume that the majority of fuel takes that path(straight back to the tank). so when they say the AD100 can do <500HP and the AD150 is for >500HP, i believe thats right. now all that fuel circulating might help avoid gelling, cause my truck cold started fine(2F) while my bosses' 3 08 chevy's were dealing with plugged filters.

$399 + Tax I got her all installed in less than 2 hours. Got my pressure up to 20psi right away. It hardly drops at WOT. like 2-3 psi. Thank you guys for all the help. Got the Raptor 150 and it works great. Thanks. I got the gauges Fuel pressure, boost, trans temp.

I feel much better now its running 20psi. .

Glad to hear it worked out for ya...

Is over 20psi good? My new pump runs about 20 most the time but goes over that some time for a while. sShould I turn it down a bit?

Well... There is some people claiming that you can put up to 40 PSI to a VP44 without damage. But like in another thread we all found out that the VP44 has a internal regulator too set at 15-16 PSI so going over 20 PSI is over kill basically in my mind. But as long as low side stays above 15 PSI you should be fine.
