I have a 1983 Johnson V4 115HP. I only have a 30 gallon tank in the stern. I'm looking at installing some auxillary tanks forward. What do I need to connect three permanent tanks to the motor?
I found this:

but it appears that my fuel lines are 3/8. Will a 1/4" valve cause too much restriction in my setup and starve the motor for fuel or is this the valve I should use? I was unable to find a true three way 3/8 valve. Just the one that did 1, 2, 1 and 2, and off.
I found this one that I htink is 1/2"

But it's prohibitively expensive and I'd have to bush it down to 3/8.

The 1/4" referred to is the pipe thread size, not the nipple I.D. Besides, even if the nipples are only 1/4" (I don't know), even if they are, it is only for a real short distance. It is when the restriction is for a long distance of several feet that it becomes an issue.

EDIT: OK, I looked it up and here's the 1/4" pipe thread X 3/8 hose barb fittings you need.
