fuel vaporisation

Paul, there was no issue with the fuel supply. issue was with the electrics - coil - This is an example of why we replace all the service items with new ones before trying to figure out the problem. If done one item at a time you will probably find the fault during the process otherwise you know that all those things are good. In this case starting the car to adjust timing etc will no doubt cause it to conk out fairly quickly and you can go ahead and check the rest of the circuits and electric equipment to find the culprit (or clear the electrics as not the issue)

Paul,
Check that the bypass from the carburettor tower to radiator is clear; feel the small hose from the centre of the V to the radiator. It should be hot when the engine is hot, showing that coolant is running through it. I was getting serious vapourisation on my V8, despite electric fuel pump, but cured when I unblocked the bypass. I am using Facet pump mounted on th inner wing panel, near the brake servo, with connection from the original Rover fuel line from reserve tap, and the pressure regulator in line to the Carbs.
 
I had a fuel problem, but I left the pipe running along the LHS of the block, and ran a length of heat resistant tubing (Firesleeve) over it, from the pump , along the block and over the bellhousing. solved several possible issues.
 
Jut for interest, I use a pusher pump from the tank and run the fuel line up to the bulk head, along the outside of the engine bay , along the inside of the NSF wing, and back into the engine bay near the screen wash bottle. The fuel doesn't see any engine bay temps before entering carbs..
