Now temperatures have reached 80ºF over here in the Netherlands, my PV444/B20F demonstrates an annoying vapour lock problem. When I park the car for a few minutes with the hot engine switched off, it will take at least 15-20 minutes before I can drive away again. Cold water on the float chambers does help of course, but I prefer preventing the problem.
I have isolated the fuel hose with a ½” waterhose but that doesn’t help. Between the 2 HIF6 SU’s and the manifold there are phenolic blocks and a heat shield as well (from a 144), but that doesn’t help either. The heat shield is a bit small though. A 82ºC thermostat is mounted and the original fan plus an electric fan is mounted with a 85/75º fan switch in the lower radiator tank, which seems to be adequate for sufficient cooling (the engine does not overheat).
I have run out of ideas how to cure this (except converting to LPG). Who can help?
