Gas tank too big?

Got tired of filling up my Honda clone every couple of days. It especially sucks when I run out on a job and forgot to bring along extra. Northern had this 8 gal tank on the clearance isle. Installed it, works great..........except..........aparantly the carb float wont cut off the gas. Theres a couple gallons in the bed of my ranger now. Did I do something wrong, is there anything I can do to remedy it?

The extra fuel weighs more than the fuel in the normal tank and is pushing the fuel past the needle and seat.

You could do a couple of different things, not sure if they would work though. You could put the ball down and let it be gravity feed at the start and finish with suction feed, except that wont work...

You could do a rube goldberg and put it on a spring system to let it raise as the fuel level depleted...

Or, you could put the original tank back on, and hiik it up as an attached refueling station, and when you run out, you open the cap, turn the valve and fill the tank.
 
An automotive fuel pressure regulator set at 1psi should limit the pressure to the carb. You could find a flatter tank to add capacity instead of that taller one, same height as stock equals same fuel pressure.
 
I din't know you could put a bigger tank on them.... good idea

I did some rigging to get it on there but almost looks stock. Ought to be able to go several weeks between fill ups. Like I said it was on clearance, not like I have several gas tanks laying around. What do other units use that have bigger gravity feed tanks? Thats what I thought I might be missing.
 
Bigger floats and float bowls on their carbs. They can resist the extra pressure that way. No way I can see too modify the carb cheaply. Get a fuel regulator.
 
What we did to solve our refueling problem is that we put a 115 gallon diesel tank in the back of the trailer with a performance fuel pump. Pumps 125 gallons an hour. All the excess fuel that is not being used loops back to the tank.
 
Just stick one of those in the back of the Ranger, Roger.
 
Northern is having a big sale so I stopped by and looked at this thing. Big tank, gravity feed 13hp honda. The only thing different it had was an inline fuel filter. Ill see if that makes a difference. Ill take the bowl and float apart too. It was an open box clearance, maybe something was in the tank that made its way to the float and jammed it up.

Will do, where should I put that 115 gal tank?

Just get rid of some of that crap in the back.
Or put it in the passenger seat.
 
Thats what I thought too. Most floats Ive messed with have had a metal tab the needle valve mounts to, bend the tab to adjust the float level, this one is all plastic.
