Curious if they will fit the stock rails without modification, TIA.
stock rails work fine with spacer. if you want to go to a return fuel system u will need better rails to feed pump then out to the regulator.
They have a specific part number for the 11-17 5.0 and you still have to use a spacer? Is this only if you are using the stock fuel rails? I just ordered a set of these, can someone post up a link where to by the spacers? Thanks
