Some years ago we had a problem with the build up of crud in the tank on our tornado dive boat,. After cleaning the idle jets out umpteen times on our lovely yam V4 we took the bull by the horns and cut a large hole in the top of the alu tank with a hole saw. I then flushed it out wit endless buckets of hot soapy water. This is after syphoning all or as much of the fuel as I could get out. The crud inside was surprising as well as some water. Droplets. After the final flushing with petrol it was all left to dry and we made a plate with a screw cap to fit on. Not had a problem since, fingers crossed. Dave j
