I'm putting a TBSS intake on a 1999 silverado and the fuel rails are different. Any suggestions on what rails might work or what modifications could be made?
Thanks

 

You can just take and replace your cross over tube, with a braided one. You will have to do a little fabbing after you cut the old one off to get the new one fitted, sealed up, but then your good to go.. I am not sure if the height that the rails mount on the TBSS intake is the same as out intakes, so some work might be needed.. Or you can do like I did. go with aftermarket rails-fpr-lines...

 

John, could you possibly give me the source and PN for the after mkt fuel rails?
Thanks

 

U have to.make spacers for the factory rails to work and the bolt hole on the fuel rail has to.be drilled over a little bit so.it will line up. Or go with aftermarket I just did that to mine still had to.fab up brackets to hold it down cuz they don't make a exact on for the tbss only pics I have r on my phone ill try and send them.to my email to put the up on here

 

Here is a thread I posted. I still do not have it on the truck, but all is finished on the intake, along with the braided cross over in the front.. Some guys say not to run the fpr this way. I have seen it done over and over with out any issue.. It is set up so that the factory lines connect to it for feed, return.. so both feed and return is going through the fpr, vs a feed to the rails, then return through the FPR( yah it sounds tricky)

The rails are from prof products, are for the ls1, actually I think I have the ls2 rails, no diff other then mounting hardware I think, I didn't use none of the brackets anyway..

Just snapped this real quick, nothing big, just the front cross over, btw I have mine set up to use the truck(shorty) injectors)

 

That's the same kit I got there nice and cheap but mines the ls1 return style

 

Hey mangled I had to put my cross over in the back or it was hitting the back of the alternator

 

What kit are you referring to?? The rails for a return or return less are all up to the way you set them up..

Guess I will have to cross that bride when I get to it.. Thanks for the heads up..

 

Well I bought the kit that had the regulator with it and ur welcome good luck with it ill post pics of.mine tomorrow

 

Oh never knew they offered a kit with rails and fpr, if that is what your reff'n to.. The fpr can also be set up to use return or both..
