With our injector choice down, we decided to upgrade our fuel rail with this Skunk2 composite part. The Skunk2 fuel rail is made of fiber reinforced thermoplastic. Plastic was used for its lower thermal conductivity. The rail has a large ID for better flow and OEM type fittings for pressure feed and return. The rail also has extra ports for fuel pressure sending units and a damper if you wanted to use one.
To install our head we first set our ARP studs in place and laid down the head gasket.
In one area, at one of the oil return holes the gasket didn’t line up perfectly.
Since this is just a gravity fed drain that is not under pressure we don’t think that this is going to be a problem. The sealing area is a bit thin here so we will put a small amount of sealer in this area just in case.
Howard lowers the head into place carefully.
After lubricating the stud threads and ground hardened washers, the nuts of the ARP head studs are spun down.
