Just an update on the vapour problem. I added a neoprene gasket to the underside of the flange and with the screws coated in Permatex, the fuel does not weep anymore through the sender. Fumes may have also been exiting through a faulty connector on the fuel return hose at the fuel pump but this has also been replaced. So all good, test runs are now fume free. Thanks for all the assistance from the forum and to Craig (raaps) for the time at the workshop. Next job is to get cool air into the air filter as hot air from the fan is affecting the sensor at the air intake - lots of great ideas from recent postings but I'll probably keep it basic.
