So I got my tank sumped (two -10 outlets for pumps, one -10 drain hole) the inner coated, and finally after locating and drilling for a return powdercoated. Now I kept the whole circle top piece so I would still have a sending unit for my gauge, but I am thinking about using the old fuel supply line and the metal tube with the 3/8 hose on it for vents and just capping the other two lines off. Now my question is, is that too much venting? is it even possible to "over-vent" the tank?

 

Ya got the right idea,just keep going the way you are going.

 

good, I will proceed as planned then, thanks!

 

I'd just use the old vent line in the sending unit with the factory control valve over by the frame. I think this is rollover protection.

 

I was just going to use that on one of the lines, and use a check ball valve on the other with possibly a little filter.
