so i bought a fast lsxrt and the billet rails but how the hell do i adapt them to my return style fuel system?

 

You have to buy a fuel pressure regulator to run the billet rails. Also the an fittings and hoses. I have a post, ill post it up. I think I spent about $400 on everything to run it. But I bought all earls products, you could buy wahtever brand you want. Hope this helps.

one more thing when i put in my injectors they seated to the bottom but its not very tight. is that normal? i know on my stock intake its a pain sometimes to seat them all the way. maybe i need a bigger bottom o-ring?

 

When u buy it brand new fast send u bigger o-rings so call them and see if u can just buy them

 

ahhhhh thats what that other pack of o-rings is for. let me see if that changes everthing

 

With the other ones u will need.to put grease or some lube on them lol or really had to push in

 

yep that was the issue. "lubed" them up and they snugged up perfectly. its a shame the instructions fail to mention the need for different o-rings. even the billet fuel rail instructions did not mention it.

 

Yea there instructions r ok but ur right they didn't say anything about thoses

 

yeah i agree but experience is worth way more than the words on paper.

 

Yes indeed it is
