Damn iphone

I ment to say you need a 255 gpm fuel pump. Or boost a pump.

 

Ok I understand that. So the pump isn't strong enough for my injectors so they are only putting out as much as the pump can. So if I get a bigger pump or something along the lines then I'll be using the full amount of the 55lb injectors.

I see. Makes sense thanks. I'm not sure I want to go that route yet but I'll do the most I can with stock fuel pump and stock motor internals

 

From what ive read 12 psi is safe on stock internals WITH A GOOD TUNE.

Personally i recommend ya get a fuel pump then the custom tune so everything can be incorporated properly.

 

And i went and checked because i knew gpm was wrong. You need a 255 lph pump.

 

You need twin 255lph pumps.

 

My peraonal preference is the dual in dual out. No sense having two mufflers. Double the weight and expense.

 

No we don't. Ford went to a returnless fuel system with the 04 up trucks that uses voltage to control fuel pressure. That's one reason you can't just throw any standard style pump in the fuel tank to boost fuel delivery.

 

Yea big horsepower guys go to return style to put in massive pumps.

 

well this gives me alot to think about, what brand fuel pumps should i be looking at?

 

Thats right. My mistake. I do recall Troyer saying that. And he told me we have to go to a return system if and when I go built. Basically anything above 700hp. Sorry about that. Had the details crossed in my mind.

 

Walbro's give the best bang for the buck. Aeromotive is another choice. Possibly Bosch.

 

alright thanks ill check them out after work today!

 

so i just need to replace my stock pump with a 255lph and it will be putting enough fuel for my 12 psi or more? how much psi could i go up to out of curiousity?

 

No twin pump setup via jdm or Troyer

 

The highest psi you can do safely on stock block is 12 psi and thats with a damn good tune.
