Can I power it off the wire going to the stock pump, or do I need to run fresh power to it and use a relay? Also, can I just cut the stock fuel line by the fuel filter and use rubber hose to hook it up, or is there a better way? Thanks...

 

You need fresh power and a relay.

You need to intercept the fuel line before the filter, run it through the pump, then into the filter. Rubber hose is fine, as long as it's rated for high pressure. You should also use fuel injection clamps for the hose.

I think Magnacharger has a slick kit with all the parts needed. I don't know if they sell it seperately though.

 

as far as I know, you can't buy it from Magnacharger. They buy them from this guy.

i ordered one last week, hope it gets here soon. supposed to be plug and play. complete setup. $200+ Hope it's worth it.

 

Cool, Thanks I'll check it out.

 

Are you adding a pump (helper pump) or replacing the stock with an external?

You can use a Duramax Sending unit also and plumb like this
This works especially well if you are looking for more fuel than the stock sending unit 3/8 line can handle.. Or if you want to run braided line from the sender to your inline pump..

 

I don't think I need that much fuel delivery improvement. I'm trying my hardest not to turn my daily driver in to a race truck , but its so hard not to want to go faster . I just haven't decided if I want to put an inline helper on it, or drop the tank and put a 255 lp/hr in it. Just need a little something to help feed the 42 lb/hr injectors.

 

Ok, so I just ordered an intank 255ltr/hr pump from Livernoris Motorsports. Should be $133 shipped with an install kit. My fuel system should all be good now.

 

got the kit from Under Pressure. The instructions are incomplete. No wiring diagram. GREAT!!!! He sent me part of the Radix install instructions. There's a relay of some sort that isn't mentioned in the instructions. Not sure exactly how to hook it up. WTF? I wish people would be honest when they say their kit is complete with accurate instructions.
