Revvin7 Earls has a similar part with out the oring end and restriction.



if you go under summit racing it is ear-9919dfh



I only used one of those for the entrace of fuel to the primary rail. The part you are holding is the power steering adapter which will restrict flow ot the rail.





I just did my convertion and no problems.

its fine now, and IT RUNS!!!!!!!!!!

Here is the difference, the black ones are the O-ring an flare vs the flare union

the o-ring flare is not tapered vs the tapered ends on both sides of the normal ones..

much better! Just got my other 90degree too...

Back from the grave!

Did anyone ever do a write up on fittings/adapters needed to convert stock fuel system to aftermarket fpr and parallel fuel rails? I just ordered my fpr (dual -6an inlets and one -6an return) and don't want to experience the problems/costs that everyone else has gone through. I want to replace everything from the fuel filter to the fuel rails, and I am going to stick with the stock rails (S4) with metric adapters for the an lines/fittings. Any help is greatly appreciated. If there is already a thread on this and I missed it in my search, please point me in that direction. Thanks again!
