Is anyone familiar with these valves? A less than stellar engine guy decided on his own to reroute my fuel lines. One of these is for fuel to the engine. The other is for the return line. He didn’t mark anything so I’m assuming the arrow on the handle points to where fuel is routed to.
I have two tanks. There was no reason to make this so complicated.
Where does the open end (where the valve isn't pointing) go? I hope it's not "open"?
Assuming (maybe that isn't appropriate in "a less then stellar" environment) that things are routed correctly, the key is from each tank, then supply runs through your filter(s); and the return is unfiltered.
SailMaster, your situation is a bit complicated because YOUR RETURN and YOUR SUPPLY should go to the same tank in normal operations. A good deal of the fuel going to your diesel is returned back to the tank, unused. If you send it back to the wrong tank, you can essentially empty a tank and overflow the other one. (There are other potential consequences if you had one tank that had questionable fuel, and couldn't separate the good from the bad, so to speak). The coordination of is usually accomplished with valves that are linked by "lever arms" in a built-up manifold, like the one we have on our J/Boat. (If the "engine guy" is trying to provide you with some fuel transfer ability between tanks, that would be complicated -- especially if he didn't have a very set procedure, labeling, manifolds, pumps, filter locations, etc.)
Why don't you draw a simple diagram (or annotate some photos) that shows the full system, then it would possible to comment more appropriately.
Why did you reroute your fuel lines? Did you just add a tank? or what?
