Inlet manifold

On my spitfire (ST170 engine) I used 8mm copper for all fuel lines. And Goodyear Barricade hoses....

I think you can use 6mm for the return but no real advantage, especially if you buy a roll of 8mm copper.

Yes Dave. It wont need the same flow obviously , but as the fuel pump return on the tank sender was the same size as the feed and also at the fuel rail end I stayed with it. Plus I had a long roll of it

After some bypass advice from Jeroen, I ran it up today with 2 T pieces and a restrictor between them. Only tried the car with heater valve open (hot) and with an infa red gun tested the temps around the bay. Looking quite promising so far (rear) stat opened nicely and temps seem quite stable. I was running electric fan "manually" and temps got to 90 before the fan brought them down again. Got some finalising to do tomorrow weather permitting. Heater pipes quite toasty so I'll try the heater fan back on and see how it goes

Cheers

Just re-read this thread looking for something. Happy to report 4 years later and lots of miles and never had issues with coolant. Heater is nice and ecu controls leccy fan which only comes on travelling very slow or stopped on hot days
