Keeping it Cool, LS fuel


So,took the Canso on it's first big cruise of the year up to Comox on Sunday. About a 6hr trip there and back (1/4 way to Manitoba). On the way up at 6:30 in the morning she ran great! Cruised at 120kmh,sat back with tunes on. On the way home (mid afternoon) I could hear the fuel pump cavitating and was getting worse. Stopped in Duncan and topped up with cool fuel and pump noise went away.  Running the truck intake which uses a fuel return line. For u guys not familiar with the system,the fuel from the pump runs up to the fuel rails at motor and what is not used runs back to the tank by means of a regulator in the rail. This means my fuel is running over a hot trans and motor then returning back to the tank. Also my exhaust dumps out the back(most r behind rear tire) and only about 1/4-3/8 clearance between exhaust and tank, so this is not helping!! So,here is my fix....hopefully!!! Going to dead head/plug the fuel rail return port and install a regulated fuel filter (filter with pressure reg built in) near tank and insulate exhaust running by tank. Progress so far.

Lathed down a 5/16 bolt for rail plug

Cut some 2 1/2 exhaust pipe in half and clamped over tailpipe with 3 layers of welding blanket between. Hope this works or I'll be packing a trunk full off ice through Sask in August!! Yes Doug..might be a beer or 2 mixed in with it.

Just dump a cell in the trunk and be done with it.

Hopefully it works. Same idea as on my Dad's car, only he has the '04 intake with no return so has to run the 'vette filter/ reg like you are changing to. We are no where near test driving so can't say what it's like.

Well..after hearing my pump howl all last year from the hot fuel figured I'd pick up a new one (will keep old 1 in the trunk for backup). New pump and filter installed tonight,just need to hook up wiring,put plug in rail and remove old return line. Once that's done,some good rear shocks. Thinking coil over or double adjusting....car is soft on the down stroke.
