OK, so we had a little problem with fuel getting to the engine last time out. Â
A little plubing project was born, to try to keep the same situation from happening again.
Here what it looked like before we started. Â Andrew had already pulled the filter off, it was just to the right of the pump, but was mounted with wood srews to the transom and just about fell off in his hands. Â Something different would have to be done. Â I was thinking about mounting everything off a fabricated bracket mounted to the swim step hardware poking through the transom, but decided against it.
You can also see the old T fitting tied up to the wiring harness, we tried to just plumg the left hand tank to the pump, but the boat still wouldn't start. We found out why, but that will have to wait.

OK, so where to mount everything??? I needed to mount the new fuel selector and the fuel filter. After looking at it a while, I decided to use some aluminium strap along the small bulkhead on the rear piece of the dog house. Off to Lowe's I went and came back with some aluminium, hardware, and what I hoped was a pretty good plan.
Here's what it looked like about half way through mounting everything up. The selector is mounted, and I'd just got done drilling the holes for the filter.

Sleek, not sure it's going to work with the  selector hooked up like that. The tanks normally connect to the "arms" of the valve with the output to filter/pump/engine being the center leg. Your pic shows the left hand tank connected to the "leg" and the output being off of the left "arm".
Since it looks like you have an electric fuel pump(first pic, just above the jet?), you might want to try moving the filter to a point after the pump instead of before.

Well, that's what I thought too... But the valve (a 3 way) is made so the L/R tanks feed in to the middle and outside connection, and the pump is fed off the inside... I should have bought a 4 way selector and it would have made more sense.
Yesterday, I plumbed it every way imaginable, and still it bleads off... as soon as you crack a hose end... whoosh... out comes the gas. Turn the pump off for 30 seconds and then back on... nothing.
I'm beginning to think everything is mounted to high in the boat.

Let me be a little more clear.
I turn the pump on and no fuel pressure. I crack a hose end to blead the air out, and fuel starts flowing and I have good pressure as long as the pump stay on.
OK... now...
I turn the pump off, and let the system set for a minute or so, then turn the pump back on, and nothing... no fuel pessure. I have to re-blead the system to get fuel to flow.

| Quote (stingray @ Sep. 19 2005,5:15 pm) | was your "T" for both tanks below the top of your tanks? That could be part of the problem.  you mentioned before you thought it may have been to high? I've never done one from scratch, always just replaced what I had
maybe unbolt it all and lay it low in the boat to see. |
It was aprox. the same height... The T was pretty much just hanging by the fuel lines. The Valve is pretty much the same height as the top of the tanks, which after messing around with it this afternoon, is to high.
What I would like to find is a couple check valves, something along the lines of a Bassett T-valve for headers (except just an in/out fitting instead of a "T"), but as far as I can tell, no one make one. I could put those at the tanks, and keep the fuel from siphoning back. Otherwise I think I'm going to have to remount everything lower in the boat.

Off came the carb and I tore it apart. Water water everywhere. Must have sucked a bunch of H20 off the bottom of the tank when we ran it "dry". Motors don't run well on that stuff. 
instead. 
, finally I just ripped it all out and started over again( I know its not wiring its plumbing butit applies all the same)
