Yup, we've explored that possibility too, but the filter was blocked by some quite hard deposit, almost like paint. I suppose such a microbe growth could have developed in the last 9 months/3,000 miles & suddenly manifested itself BUT - if the filter was blocked, it wouldn't run, rather than cutting out after around 230 miles, i.e. when I judge the tank to be 1/2 full, given that the pick-up is at the bottom of the tank.
That said, quite prepared to run the appropriate additive/cleaner through the system - if someone can put me onto one.
