Title: electric fuel valve
Post by: BennyParadise on May 08, 2017, 03:40:47 PM: Im redoing and cleaning up my fuel system. Im thinking about removing the fuel valve and have the lines from the tanks run direct to the fuel/ water separator instead. running both tanks at the same time. Freeing up some transom space etc... Any more experienced jet boaters out there see me running into problems? besides not being able to switch between tanks anymore? pros? cons?

I just made sure that both tank lines are exactly the same length so that they will draw evenly, which they did pretty damn close. My new boat is plumbed that way too, but I haven't even taken it out yet lol.

And also if 1 tank does go empty before the other you might start getting air in the lines causing you to starve a little but...... ive never had mine get that low, and the separator should help eliminate that if the filter stays full.

But if I go to change it most likely I will do exactly what shocker said. Jmo though

My old Hawaiian never had a valve. Ran both tanks direct to the water separator. That's all I knew so it worked well for me. Gas guage was never accurate but I just drew little hash marks on my ski flag at full, med and Low and just kept dipping it in the tank through out the day. They seemed to never draw evenly though. Now that I have a switch I don't think I would ever go back. Doesn't take up really any room on the transom and gives me piece of mind!
Same with the battery. I have a manual switch over and I know that if one dies I have a fresh one on the other side. Highly recommend it

Post by: el mojado on May 09, 2017, 12:37:02 PM: I run manual valves at each tank, one tank at a time. Never any electrical issues. I only reach back there once; when I run out of fuel in one tank. I also run 2 gauges, but I have the room on my dash.

Any recommendations on brand, etc?
The pic is the original valve which seems to draw from the port side fuel tank (slightly) even if the starboard tank is selected.

Post by: Nick25 on July 07, 2017, 07:01:14 PM: Question. My tanks are setup to pull evenly at the same time. I want to add an electric switcher but how would I wire the gauge in with it?
