Definitely will clean the tank. Has anyone used the three step process that Moss sells? It sounds pretty easy to use and with the weather like it is, I have plenty of time.
Dave, I have been doing a lot of reading about MGs and somewhere I read that I could use a square run-all-the-time fuel pump in line with an SU type and have it wired to a switch to use in emergencies. Not sure how it works but its a thought.
Thanks everyone.
