ya if you want higher pressure out of a blue I think it is just a spring you change out. . . cheap.

 

I planned on putting a airdog 150GPH electic pump on mine. Any reason I should coose Holley over that one? Other than the price just went up by $100.

 

If you have the airdog already I would just use that. The holley blue is 110 gph, so the airdog flows more than an out of the box holley blue. The holley black is 140 gph, so right there with the airdog, I dont know what the cost is on an airdog though.

I have an aeromotive A1000 laying around from my integra project that I will use in my truck if the holley doesnt flow enough for me.

 

The piston pumps wont will the crank case with oil if they go bad like a stock diaphragm pump will. But I agree, if you got the money a good electric pump and regulator works great.

 

Go with the A1000. I'm not afan of blues, they work good for a mild truck but are noisy and tend to go out at the worst times.

 

But what is the max psi I can push to the injector pump?

 

As I said earlier, @ 15 psi starts affecting the timing in the pump.
Any more than @ 20 PSI, then you run the risk of pushing the front seal out of the pump, unless you do machine work to the pump to retain the seal.

Mark.

 

Any body who decides to run a holley pump needs to be aware to remove the screen on the inlet side and it will starve the pump of fuel (happened to me twice), and follow the directions.

Me and my dad mounted mine to the fire wall upside down and it let fuel leak into the motor. Long story short, read ALL the directions so you dont void your warranty.

 

sweet good to know.

 

What mark said. you need a regulator if you run the A1000
