fuel return & head re-torque

[Anonymous]

Hi
hey I have a quick question for someone in the know plz.
Ive just set up my 4.1 xflow in a jet boat as yet I don't have a custom made fuel tank. The one I am using does not have a fuel return pipe fitted for me to use, My question is. Can I ' T ' the return fuel line out of the fuel pump into the supply line? and it just ends up doing a circuit.(its one of those alloy ones not the glass bowl type)
Its been mentioned to me to just plug off the return pipe, I don't like this idea cause of the back pressure created inside the fuel pump. I expect it would soon kill the diaphragm rather quick.


The other question is about the re-torque of the cylinder head when a new head gasket has been fitted. Now it seems that we just idle the engine up to a norm temp and then its due for the re-torque. Does this have to be done while its still hot? my sockets wont fit between the rockers so it would mean taking those out to be able to do it, not much fun if the things are hot not to mention the amount of time involved. The engine would be cooling in the time it takes to remove the rockers.

Thanks for any advice


Its a good feeling when a rebuild starts after a first time engine strip down

Normal practice with these motors is not to retorque, but I'd suggest if you want to do it, run up to temp, cool 2-4 hours (so the head feels tepid) and retension.

Run your fuel return line into the gas tank filler neck.

hmmm. I just put a new exhaust manifold on this past weekend. Do I need to retorque it when hot?

I would re-torque after a few heat cycles. I try not to torque bolts (esp exhaust) hot as they are weaking and could easily yield a bolt.
