Im going with 60lb mototrons and I have an inline pump from the Vortech, although Im not sure what it flows. Ive got the return style fuel system. Would the Radix intank pump be a good idea? Is it still a direct fit for us with return style systems?
Setup is 6.0, 220/218 563/565 cam, STS GT67(may go with a GT70), meth, Stage 1 heads etc.

 

I believe the radix pump is an inline pump just like you have. A stock pump with an inline booster should flow plenty on fuel for 60's.

 

i gonna be running dual 255's in tank with 60's. i don't think a inline is gonna keep up with 60's

 

Your new setup is gonna be a 6.0 with the sts? Have you researched tuning those 60's yet? The way I understand it, the stock intank and inline(255) is just fine for the 60's on a 6.0/FI. It's when you run out of injector that it's an issue cuz it looks like your out fuel. And you surely aren't going to be running out of fuel anytime soon with 60's on that setup...unless you go blasting down a mile or two stretch with only an 1/8 tank of gas...

 

one inline 255 does not have enough volume to keep up with 60's

 

So should I look into swapping the walbro intank in? Does anyone make one that fits without modification??

 

i don't think anyone makes a direct replacement yet. if you do a search on here there is nice write up on how to do it. i did mine myself and it wasn't that hard. futral is doing the dual intank for me.
i recommend doing the intank.

 

yes, the radix pump is a direct fit intank pump, thats what i run , i called them and got one for 120$ , go to magnuson's website, they have install instructions there you can read thru and print, good luck.

 

This is what I heard. From what I understand, it is the Walbro that is modified to fit the trucks. Its a 255 isnt it? Is it fine to use with the return fuel system?

 

i was told by magnuson that the intank would only work for '04 up.
