LS engine swap info

Fuel system (any chance a mod can move this post up?)
The LS engines require 58-60 pounds pressure at the fuel rails. Older fuel rails had a regulator on the rails and there is a feed and return on these engines. On the later fuel rails there is only the feed on the rail. You need to have something like the filter regulator shown below to return the excess fuel to the tank. Some of the tanks these engines came with did this internally in the tank.

I don't know how long this will last but a decent deal on the regulator/filter and he will take offers for less I am told
