Fuel delivery problem

Well, here I am again with another problem.
The engine runs nice and smooth at idle, but when I accelerate, it sputters and dies, then is difficult to restart. I had run out of gas and figured I'd sucked up gunk from the bottom of the tank. I took out the fuel pump and cleaned the filter, then reinstalled. It seems to be working fine. I replaced an inline filter as well. No good result. Engine started right up and idled smoothly. I let the engine warm up to about 180 and then tried to accelerate; it sputtered and died. What should I try next?
 
check fuel bowls for water

Hello Perry,

I would, also, blow back down the fuel line in case something is blocking or partially blocking the inlet.

Ditto!
I've had this problem and it's a tough one to diagnose.
 
I had a loose connection at the top of the fuel tank where the hard line connects. Tightened it up and it fixed it right up. I had similar symtoms.
 
Sounds like fuel starvation big time.
What model and carbs have you got?
To check the fuel line, pump etc use a 2 Ltr plastic bottle mark the 2 Ltr line, remove the fuel line from the carbs and put it in the bottle, turn ignition on and carefully record the time it takes to reach the mark then relate the output to the theoretical pump delivery.
You have to eliminate each possible cause.

I had the exact problem.The cause in my case turned out to be a filter inside the tank,a well clogged up filter at that!I was a little supprised to find the fitting(out-let pipe to tank) was welded in.A removal of this filter plus the addition of an inline one has ment happy motoring.I have not heard of an 'in tank'filter before.

About the only thing that can get past the inline fuel filter would be water. Since water is heavier than gas, it accumulates at the bottom of the tank and would be one of the first things sucked up by the fuel pump. So running your tank dry should'nt be an issue as far as water is concerned. I would concentrate on the area betw
een the inline filter and the tank. Especially the fuel pump and the line between the pump and tank. Sky
