After i built this sled, i had it all bled out, NO bubbles in the line anywhere. I had a malfunction with the oil line from the bottle to the pump so i pulled it to install a new line. Thats when i started getting bubbles, i have put clamps on everything that would need them, lines where TIGHT, they were a pain to get on and thats how i wanted it. So im thinking something with that pump is allowing air in. I can clearly see all bubbles, most are small but once in awhile i get a bigger one. I could tell my sled was running really lean today, we had a foot deep of new and still getting hot so i checked the lines and saw the bubbles. I stuck the pump wide open and watched all the bubbles run on through, then ran the sled, after 10min got more bubbles, ran them through again, i did this probably four five times and still got bubbles. Im thinking the pump is wore out or something like that. I've thought about running just premix but then i risk my crank bearings. Maybe ill drop in a new pump or pull this one and check it all out. Hopefully ill figure something out here....
