So this is actually the third fuel head you have had in a few weeks? What was wrong with the original one that led to you replacing it? It's hard to see how three separate fuel heads could be faulty or leaking. I have never heard of that sort of failure in a new fuel head nor even know of any examples where they required replacement - other than for people moving to the generation 2 head due to the fuel heater connector problem.

Perhaps you should take it in to Eddy's service shop and get him to check it out. See the recent posts to grt Eddy's number.
