i just installed a fuel pressure guage an it jumps from 12 to 14 alot an don't to 10 when i take off an at cruisen speed i think i need a better pump to keep up let me know what ur guys do an what kind of fuel presure u got.

 

Bump, what about that Holley black, think it might be an issue. I haven't known anyone to have much luck with them. I thought they were fer gas.

 

I did to...

 

its for all kinds of fuel the others r only for gas so i dont know

 

Can you adjust the pressure on it? I know on some models of the Airdog II you can...

 

you can adjust pressure on the black. you got the plug on the side of the pump. pull it off and there is a spring behind it. stretch that spring put it all back together and check your pressure.

 

Unless you're running a pair in tandem, I wouldn't trust those Holley or similar knockoff types for anything more than a backup.

 

stretchd the spring out got me 4 more psi but still gonna go with an airdog2

 

This is my opinion - I used a FASS 150 on another truck worked well. Original Airdog should be a little better - he owns the patent on 2 air removers - the FASS has one. Plus the Airdog 2 has regulated fuel return - I want a lot of fuel to the pump as it cools and lubricates the pump and the more times your fuel goes through the filters - the better polished it will be. Plus the Original airdogs are at a steal price right now below $500!

 

you need at least 43 to run it on properly,normally they run around 45-50 pounds,but if you got 43 it will run right,good luck.
