Fuel mod question.
 

I have 200k miles on this 2000 ram2500. BHAF getting done today. And looking at 4" exhaust and a programmer later. In my head , I am thinking 350 to 400 hp at the most when "I'm done" (famous last words). Is the Airdog 150 for me?

Might be overkill, but better fuel makes for a happier truck. If this is for a 24v, and it has the stock lift/injection pump I would do it without hesitation. I'm rusty on my VP44's, but that might be a limiting factor as a stock VP may not be able to give out that much PSI...

the 150 air dog will do fine. Its 150gph still at 17 psi. It just a little over stock. VP's are extremely fragile when it comes to fuel. its better to leave room for improvement then to go "oh ****" when your pressure drops!

150 gph is more than enough. I've got a 95 gph on my 13mm p-pump, it still holds 20+ psi at WOT.

This si what you want. You will not regret it. Even sold right here on DTR.

how is the fuel boss for reliability

100 is big enough for 400+HP

Fuel boss is, IMO, more reliable than an electric pump....it cant blow a fuse or burn up. I've had mine on for well over 2 years now with not a single issue. Only thing that can really go wrong is lose a belt, but it's rare.

If engine is turning you are pumping fuel. I did not even leave the stock pump on, just installed it as a stand alone.
