Raptor Pump

[Goosekiller]

I am getting ready to install a raptor pump along with my stock pump and was just wondering if anyone has done this and how it has worked for them. I also am installing an ITP reg return when i do this. I also have another question what are the fittings called on the stock fuel pump? i need to get a hose made to go from the stock pump to raptor and the people that are makin it want to know the size and type of fittings. And if anyone knows or if a vender on here can make it pm me because i would rather give someone on here the business.

Thanks steve

Why would you use the stock HFCM to push to the Raptor? The raptor is designed to be a replacement for the stock pump, with the AD 100 - 150 to be used as the pusher with filtration/water sep.

I'm sure you already know all of this, so I'm just curious as to why you'd want to set it up this way...

Really that's what i have started thinking i was told it would be fine but i have been researchin it and i am finding out i may of made a mistake.

I was told it would be fine because i have stock injectors.

The stock HFCM will keep up just fine on stock injectors with the addition of the reg. return and an Airdog pusher pump. That's what I run and never drop below 52-54psi. I have the regulator set at 58-60psi. I might add a raptor in the line someday, but I would need much larger injectors before I'd even think about it.

I asked someone at pureflow about what you said shu and the guy wrote "A pusher pump should absolutely not be used with either the airdog or raptor. This came directly from one of the engineers here." My question is how should the raptor be used then and i think i know what you mean about a pusher but could you explain that to thanks.

I have a raptor pushing to a stock pump works great.

This statement by pureflow sounds kind of weird to me, meaning easily misunderstood. The way they originally designed the airdog (not the airdog 2) and raptor to work together was that the airdog picked up the fuel from the tank, filtered air/water out of the fuel and delivered it with high volume and low pressure to the raptor (or stock HFCM). The raptor is a regulated high pressure pump providing the flow at proper pressure up to the engine. The airdog pump in this setup is in effect a "pusher" pump.

I'm guessing the engineer did not fully understand your question and gave a generic reply...

Yea maybe i just copied what you wrote and pasted it in the email thanks for all your help.
