Hey I don't know if this belongs here's I'm sorry if it doesn't but I've been looking everywhere for an answer .. I have a 05 cavalier and I bought a FPR but I can't find an adapter online anywhere to fit the existing place that goes from the feed to the fuel rail .. if anyone can help me that would be great thanks !
No adapter should be needed. What FPR did you buy?
I'm guessing you bought a universal regulator. There are regulators that bolt directly to the stock rail. They're meant for an LT1 but it's the same fitment. Aeromotive 13107 is a direct fit. The 13106 looks the same but is backwards to fit the other rail on the LT1 V8.
If you're looking just for the adapter to use whatever you have with AN fittings, there is a part for that but I'm not sure how to find it.
What do you need the adjustment for, out of curiosity?

I still might have -6an adapters that bolt to the stock rail laying around.
OP have you ever checked if your FPR fit to existing place?
