It wouldn't hurt. Its said that the stock lift pumps on the 12V are good for 500hp but I've never personally tested it or seen it. If anything an aftermarket lift pump at any level is cheap insurance policy. Theirs nothing like shelling out to 2K for a new injection pump when something as simple and "cheap" as a FASS or Airdog could have saved it.

ya i hear ya there well thanks again for the info

well the thing with ppumps is if they dont get enough fuel it will either draw its own or it will shut off it doesnt rely soley on diesel fuel to lube like a vp ppumps are lubed via engine oil

the plungers in a ppump are lubed by fuel ... so if you run the pump out of fuel you run the risk of blowing a plunger.

Also the p pump will not run with out fuel press it can not draw its own.

DDP 3's and 4's are 155°, not 145°.

call southern diesel extreme their shipping my injectors to me today

i was pointed in their direction came highly recommended

and great pricing as well give cris a call and see what he says

might save you some money --- when u figure out u shouldn't have got the 370s'

ok i will give them a call i havent bought anything yet thats why i am asking around to find out what guys have had best luck with why do you say not to get marine 370's

From what I have heard, is that the 370s smoke alot and smokes cool and all but it gets old fast. Thats why I went with Dynamite Diesel injectors. But now I'm switch my DDPs to Industrial Injection.

ya i am looking for more power to help with towing a trailer all the time but also try and stay in a budget are DDPs a good injector and if i may ask why are you switching to industrial injection

I would rather use something from DDP than II, if I had to choose between the two.
