[QUOTE="brkntrxn, post: 8630953, member: 12396"] Carlos, I should have elaborated on my experience. Twice in the last two years I have one of my twin Walbro 255 external fuel pumps go bad. Each time they went bad, the pump itself got VERY hot. Since I had twin pumps, neither time did I truly go into a lean condition. However, BOTH times my engine temps increased significantly, as in between 3/4 and full hot (I do not have a water nor oil temp gauge). I did have what I think was cavitation due to the hot fuel which lead to the occassional hiccup. In my experience, these two times the overheating occurred when I had a fuel pump going bad. Therefore, I personally cannot rule it out as a bad pump having an effect. Of course, a bad pump is a bad pump, but external pumps are much more likely to get hot. I am now running an external A1000 with a sumped tank. I am still encountering hot fuel issues, but that is because the sump is now too close to the tail pipes where they come out from under the diff. Time for side pipes. I have had other heating issues, which were cured via the items I posted above. -Kevin [/QUOTE]
