Recently finished restoring a m-f 65 high clearance with a G-176 gas motor.The tractor was a basket case when I bought it.With the exeption of the trans,every thing else was brought home in baskets.Wish I would have known about this web page then!Anyways,here's my problem.It runs the fuel line out of gas,and the tractor quits,usually when doing heavy draft work like plowing or discing.I know it's running out of fuel because when it quits I look down and the see the fuel filter is empty.These are some of the things I have tried,but have had no results,Carb completly rebuilt by denny's carb shop,he says its a-1.Removed the filter element from the fuel filter and tried it ,nothing.New sediment bowl,new fuel lines,new gas cap,I eventried to loosen the gas cap and then try it ,then in desperation,removed the gas cap completly-still nothing.The motor is modified with a m-f power pack rebuild kit and has a custom ground matched camshaft.Runs good until it runs out of fuel.Everything is new and went to great length's to make sure everything was right,and everything else is except this fuel problem.Any thoughts,suggestions,or fixes would be greatly appreciated.Thanks,Larry

Hi, Somethings I would look at. If this is a vapor problem as some think, I would look at the routing of the fuel line and make sure its the way the factory did it. Copper line may not be the best choice, it will probable conduct heat better than rubber or steel. I would make the fuel line out of the same material the factory used. Check the filter, if it is a add on I would locate it away from the heat. Bill

register my vote for vapor lock.heres what i think you should do.run the tractor until it runs out of fuel.first disconnect the fuel line at the carb and check for flow,then loosen gas cap,disconnect inline filter at inlet side.disconnect fuel line at sediment bowl.if you do this in order and still dont get enough fuel flow,there is something in the tank.if you get flow when you disconnect the filter it is probably vapor lock.

Hi Larry

Did you check the gas cap on the tank ?

if the ventilation hole is blocked it can't
allow air to go in the tank and the vaccuum created when high gas demand il will retain gas in
tank and produce the problem you mention.

Hope it helps

Good luck

Joe Ferguson

Is there a heat shield missing from the engine? I know the MF-135 with continental engine has a heat shield. If it is not installed it could be a vapor lock problem ?
One other thought, is the correct fitting installed at the carburator inlet or is there a restriction of some kind at that fitting ? Just some thoughts.

Larry, You stated the filter is empty, did you put in an inline fuel filter? If you did, does your sediment bowl run out of fuel also? It seems you may have one of two problems; 1) The fuel line is too small. 2) There is something blocking the fuel in the tank by the inlet of the sediment bowl. If you disconnect the fuel line from the carb, how fast does it run through the line? I would think you should be able to get 3-4 cups a minute, consistantly for a few minutes.

Yes I installed an in -line filter,see-through, so that I can see what's going on.I disconnected the fuel line before the filter and after the filter opened the valve,and it the gas runs fine.Removed the gas tank and flushed it out 6-7 times.Cleaned sediment bowl out alot too so dirt and particals are probably not the problem.The sediment bowl doesn't run out of fuel.Thanks for your help it is greatly appreciated.

It sounds like it may be a restriction in the fuel line. What size fuel line are you using? Is it a metal line or a rubber fuel hose? Are there any sharp bends in it?

Iused three-eighths copper tubing ,bought a tubing bender just for that specific job.The tubing runs from the sediment bowl to the carb.The in line filter is connected to the copper on either side with short pieces of rubber fuel line.That was done to eliminate stress from vibration.Thanks again for your input.Larry
