getting gas

jeep runs if prime gas in the carb 2bbl roch.Will run but stops when prime is gone mecanical fuel pump turn it over and no gas comes out of the outlet to carb was running before just need some sugestions thanx :v6:chainsawguy

 

1) tank out of gas

2) blockage of the fuel line or possibly an inline filter plugged up

3) fuel pump faulty

4) pinched off fuel line

 

yes i put new fuel lines,fuel filter going the right way for flow.Tank was emptied during rebuild of tub and frame never touched engine.All lines are correct to jeep manual maybe fuel pump froze up from sitting in the garage for 1yr?? well i will keepon looking for the obvious thank you:v6:chainsawguy

 

I had a similar problem. My jeep sat with a few gallons of gas in the tank for about a year. Pulled it out of the garage and ran the old gas out of it by letting the engine run. Then filled the tanks full with new gas. Went trail riding, and about 2 miles into trip, fuel pump wouldn't pump. I have a visible filter between pump and carb, and could see very low flow. Had an electric fuel pump with me and hooked that up, thinking that the diaphram went bad in the mechanical pump. I always carry an electric pump with a piece of hose and alligator clips in case I need to do a fuel transfer uphill.

Anyway, that didn't really fix the problem. I suspected rust in the line, and used compressed air to blow the fuel line backwards into the tank. That improved flow for a while, but would still die on me.

Suspecting rust was the problem, I used a flexible magnet which I had salvaged from a refrigerator door seal (about 5 feet long) into the tank to see how much rust was inside. Some rust, but the pickup inside the tank is an inverted "U" so that shouldn't have been a problem.

I drained the tank and pulled it out of the jeep. I removed the float to look inside and found that there was what appeared to be pieces of celephane like in the tank. I hosed out the inside of the tank with a water hose, which flushed this stuff out of the intake. Sure enough it was varnish from the old tank.

I read on-line how to clean a tank. So I next used my pressure washer and then a piece of chain in the tank to loosen the rust. Then I Pressure washed the tank again.

After doing this, the tank looked quite clean inside. I put it all back together again, filled it with gas and everything was fine. Fortunately I left the jeep outside, because I went out about two hours later and there was a large puddle of gas under the jeep.

Aparently, the cleaning operation was too much.

I removed the tank, and SimpleGreened the inside and outside to kill the gas smell and have now installed a 6 gallon plastic boat tank in back of the seat.

May you have better luck than I and hope the rust gods are not against you.

My jeep was garage kept for most of its life. It had 20 year old at least bad as in it when I got it 6 years ago. Read my intro page for more details.

Good luck and let us know how you make out.

 

food for thought here, my c60 was/ is doing the same thing. check to make sure your float is not stuck. if you have the fuel pump with return this may not be a issue. my c60 does not have a return line and with the float stuck in the closed postition there is no where for fuel to go and you could be compressing nothing more than air. easy way to check is prime the carb, remove the supply line and run it into a jug then start the engine. if your fuel pump and pickup are in good shape you should get fuel in a matter of seconds.

 

thanx guys well i finally started getting gas i have a rebuilt 2bbl roch carb it was done like new.Now iam getting gas it starts runs but is backfiring once in awhile.Iam thinking now iam getting to much gas now they said it was rebuilt to specs of the 225? maybe the air fuel is off adjustment the two screws in front?
