>I use filters between the tank and pumps that have a sintered bronze element.
Mike, are these the small blue circular Earls filters?
I had problems with these. I would regularly get fuel starvation / low mixture at high throttle settings. I finally traced the problem to the the sintered bronze elements that looked clean but were, in fact, partially blocked by invisible tiny particles. I replace the bronze elements with stainless mesh filters and had no more problems.
