After reading Mikes thread about the ball getting stuck to the spring I figured I'd check mine today.yep the ball was pushed into the end of the spring bit. back up to 16 at idle and the lowest I could get it to drop to wot was 13.5.What a mess what do you guys do to keep from losing alot of fuel. I clamped the hoses but it still was a diesel bath. Do they make some shut off valves to put in line with the big line hoses??Luke

I used to have nice bronze twist fuel shutoff valves around. Never thought to install them in the truck. They're common in marine installations for controling tanks. With gas marine engines, I installed them on either side of the fuel separator/filters, for just that purpose.

I just use a pair of vise grips on the fuel hose to the tank. Just enough pressure to squeeze the fuel line shut.

I used vise grips on the line from the tank and the line out but, the motion lotion kept coming out of the return line fitting. probably lost 2 gallons even with the hoses clamped off. I'm gonna look into some 90 degree ball valves for the 1/2 inch line. I remember last time I changed the filter it was a similar adventure with the fuel coming out all over the place.
