Okay guys having some issues here. Just installed my new curt brown racing 70mm intake and 70m s90throttle body. And with fitting in fuel rail it will hit Throttlebody. Anybody ever run into this issue before. Anyone run any other fuel rail. What’s ur opinions
na no spacer already has a flange welded on. But curious to know. What fuel rails people use on these s90 Throttlebody combos. Clearly the Perrin is a no go!
You can run the supply line through the side of the fuel pressure regulator with the other side hooked to the rail. You can then cap off the end by the throttle body, which is what I did. It also keeps a lot of the gas from running through the rail and heating the fuel. I was able to use the throttle body side as the supply before changing to supply from regulator, but I am using the Full Blown 70mm throttle body.
