[QUOTE="Dzchey21, post: 874027, member: 63"] fuel gets thicker just like oil when its cold. My set up returns fuel directly to tank, i have had it running in some cold weather 0 degrees recently. but its not common for me to run it like that. You might need to put a guage or something on the return side and make sure there is little to no pressure. That seal should basically just be a splash seal, it really doesnt do a whole lot (or shouldnt) [/QUOTE]
