Denny Mortensen Posted January 5, 2004 Share Posted January 5, 2004 I have been reading some of the threads floating around about fuel sumps in the back seat area and I find that a bit scary. Seems like it would open up lots of opportunity to take a gasoline bath in the event of a forced landing. However I can see some of the benefits to a sump type of system. Please keep in mind that I am just a new builder getting started and not even a pilot as of yet. But I was thinking, how about if a person fabricated a small tank say half gallon or so out of maybe Thick PVC pipe with end caps. Route fuel lines from the two wing tanks to a left, right, or both fuel valve. From there route the line to this small tank tucked in whatever available space. From this tank run a feed line through the fuel pump and into the filters, ext. You could run a return from the fuel injector rail back into this tank. You would need to vent both wing tanks and probably this sump tank. You could also put water check valves in it as well as the wing tanks to check for water in the system. I am thinking if this works it would allow a person to feed from both tanks or in the event of a bad fuel load they could switch to only one. It would also allow the injector a place to dump the over flow. I’m not sure about the vent line on the sump tank would the injector just cause it to dump the extra returning fuel back out the vent? I am a newbie to this group and I hear that it is not as heated as the other groups so please limit the size of ammunition. Fire at will.
