Balance and not sending it overboard. Some airplanes with main and tip tanks only return fuel to the main tanks. So you need to burn off the mains for a while first. If you use the tip tanks first the return fuel goes right over the side if the mains are full. Joe Della Barba Coquina

You need the hot fuel to dump back in the tank, not recycle right back to the engine. As for the returns on multiple tanks , I <cough wink> read about a guy delivering a Viking motoryacht that looked aft and saw a trail of fuel. Some research into the fuel valves showed fuel from A going to B when B was full already. Some airplanes do this too. If you don’t use the tanks in the correct order you will be venting a lot of $6/gal fuel over the side.

IIRC that is not a good idea. Many diesel engines return more fuel than they use. Some of the extra fuel is used for cooling the injectors. I have a vague memory of a story regarding having two fuel tanks and one fuel return line. The result was one empty tank and one over filled.

I think they only sell it with the sending unit included: http://ca.binnacle.com/p6463/MOELLER-%2335724-10-DIESEL-RETURN-KIT/product_info.html If you can’t get the flange and return fitting separately, I’d just put the other sending unit up for sale on craigslist. Someone out there needs a new sending unit. Check out the Moeller site for more info. _______________________________________________ This List is provided by the C&C Photo Album http://www.cncphotoalbum.com<http://www.cncphotoalbum.com/> CnC-List@cnc-list.com<mailto:CnC-List@cnc-list.com>
