fuel tank question
 

I have twin 20 gal saddle tanks on my V and 150 hp merc.I was wondering if I were to tee the fuel lines together will the engin feed from them equally.

All depends where you actually put the T in the fuel line . As dumb as it sounds , it will draw from the tank thats closest to the T first as I found out with my old Shamrock 20 .

See if this thread makes up your mind.

In short NO!! You can try and fail if you want.

This is a subject that's come up many a time here.. Like everyone else has said already, the short answer is no, it will not feed evenly.

Now, the long question is... why would you want them to?... It's safer (from a not running out of fuel position) to use one tank going out, and the other tank coming in.. That way you never run out of gas and you keep Seatow looking for other customers. Just somethig to think about.:head:

I was just curious mainly becuase the weight would be more evenly distrubited .As far as running out of fuel the boat don't go offshore.The lake I'm on is only 14 miles long and if I were to run out I always have my kicker motor with three and a half gals.to get me to a fuel dock.
Thanks for your replies. I'm not looking for more work so I'll leave things as they are.

Hours of labor, money, blood , sweat, and tears averted.

WellcraftV20.com....priceless!

when I first set my 74 up w/two 40 gal tanks, I tried and tried to make it work...never did, so I put individual shut-offs on each line and controlled them manually...run off one tank goin out, the other comin' back...

I got a buddy w/aSkeeter bass boat...has twin tanks and draws them down evenly from a single line...how it does it, I ain't figured out yet...:head:

You know... actually, there IS a way to make it work.. It's one of those simple things that stare you in the face and it's so easy you don't see it...:head:

The answer is simply to cross connect them... plumb the bottom of tank one over to the bottom of tank two. Then, on a second line, plumb tank two to the engine. Do not connect the line running from tank one to tank two with the line running to the engine.

Gas, like water, will always seek it's own level. So, since both tanks are connected together at the bottom, and as long as both tanks are vented so atmospheric pressure is the same inside each tank, and both tanks are sitting at about the same height inside the hull, what will happen is that as tank two is drawn down tank one will replenish it in an effort to stay level with it. The result will be both tanks will be drawn down at the same time!!! :beer:

Makes seance!

I solved the problem with buying a boat with a 110 gal tank down the middle!:hide:
