Also,is there enough current back there to run them both?
Oh, I thought that you were trying to do it in the tank. Here's a picture of that setup:[/quote]

Yeah, those look like Walbro pumps. I may try it with ND pumps if I don't wind up going with an external pump. You should try going with a Viper pump if you want something that goes in the tank. I remember a guy trying one, and it worked well. I would assume that the iper's pump will support well over 500 HP.

Well, back to the thread at hand.



...another idea is to take the stock lines running out of the fuel pump holder thing-a-do-hicky...and use both lines as outs. then when they meet up at the engine bay, take a Y brass fitting and tap them both together, then run it to primary/secondary/fuel pressure regulator and then to -10 steel braided line and back to the fuel pump holder thing-a-do-hicky and drill a hole, put a female "BUNG" there and drop an -an fitting on to it...not my personal setup, but the one I WILL be doing...when T-66 is here :P
That's a good idea.

You can run a -6 or -8 return line. -10 isn't really necessary.

Stupid question but There are 3 lines going from the engine bay to the tank.One is abvioulsy for pumping fuel to the motor?One is for Ventlation?And the other is for Return,what and why is it returning anything?

The fuel pressure regulator only allows the fuel rails to hold "x" amount of pressure. Once the pressure gets too high the regulator lets some of the fuel go by, and it gets returned to the fuel tank.

Gosh I learn so much here.So if you were to upgrade you're fuel lines would you really need to upgrade the Ventalation Fuel line and Return line?



Just the Main fuel line to the motor right...

The line to the charcoal cannister can stay the same. The return line can stay the same.

Call me dense here, but what's the point in having 2 pumps? Additive properties?
