Maybe a water meth pump would work??
Otherwise a small sauer danfoss pump would work. We use them for our diesel fired burner boxes on our N2 pumps. Good for 1200psi. They have 1/2" ports. I'll see what I can dig up.
What is this test?

this is a hold over until Opie gets his supply built back up. Been waiting on a mitusa for a month now and they still haven't been shipped. :(

I'm gonna try force feeding the CP3 with it (this is how the ATS triple feed CP3s worked). We shall see.


I know FASS offers their pump as high pressure (and that's what came with the ATS 3pl Feed) but they are kinda spendy.


May just have to wait for the mitusa to get here.

I'm talking 75-125psi. Who/what company has one? The cheaper the better since this is a test. :D


Thanks

Take a look @ a GASSER EFI electric pump they run @ 75+ psi
I used a Bosh as a trasfer pump and hooked a guage to it to see what kind of
pressure it ran, open port it ran @ 35 psi. The pressure regulator on most EFI
gasser run @ 70+ psi

Yeah, I was gonna look into them. Wonder if an alcohol-specific pump would be better since they have to feed so much more fuel than when running gas? :confused: Do they run lots of pressure when running alcohol???

I have had a couple of Weldons on drag boats. Bad MoFo's...... What kind of GPH are you looking for? Is this for the 2.5 puller?

Three way dump valves are in a lot of pulling rules. Basicly it reroutes the fuel from the pump back to the tank instead of the injection pump. If god forbid you start to have a runaway from say a blow turbo. How do you shutoff fuel from the mech. lift pump. As long as the engine spins the pump flows fuel to the injection pump. The dump valve is put in between the lift pump and the injection pump. When it is tripped it returns the fuel back to the tank.

An electric can be shut off by simply removing the power.

Make sense?

Yeah, but that's Dodge thinking.

Even if we have a mechanical lift pump and a runaway, when we shut off the key, the injectors stop accepting fuel. The mechanical pump might continue to run if there is a blown turbo, but the fuel will not feed the engine. It will do with the fuel whatever it normally does when you lift the throttle or cruise down the freeway.
