Call up FASS with the part #... Depending on which motor it actually is, it may be as simple as a spring swap... Of course if he is made of money by all means by another lift pump!

 

Thanks for the tip about the spring unfortunately no spring is available for his pump. I am going to use his pump on my dmax if I can get 12-15 psi out of it and he wants the best he can get for the money. He has the Fass system on his 05 and besides the noise and the location he likes it. None of the guys we hang with have used anything but stock or a Holley/Walbro on 1st gens. Just looking for some suggestions for a mild p-pump truck?
