Thanks 64CJ5, I have been thinking about puttining my spare electric fuel pump in line. Now I just need to find a place to hide the switch since I dont want to put another hole in the dash after my restoration.

Concerning vapor lock.  These fuel pumps suck liquid. When the gasoline flashes to vapor in the line coming to the fuel pump, the pump is starved for liquid, causing vapor lock.   The pump will push vapor to the carb with liquid, but it will not suck vapor.
Rerouting the tank to pump away from heat and/or insulating it would reduce vapor lock. Also putting a pump next to and below the fuel tank pushes cool gasoline to the carb.  My 2 cents

Update on Smokey!

Rick - You were spot on regarding the heat riser on my rig. I did not take a picture of the position since I already knew it was positioned wrong. I put the spring in the correct position, drove the Jeep for about an hour, parked it and voila no boiling of the gas issues!!!!!!!!! Man am I a happy camper - the carb was even cooler. The only thing a litle hot was the cross over tube and I expected that to be a little warm only because of the position and thin wall.

Thanks Rick...........

macrisal - I think it is really worth the effort to fix the HR and heating issue. You will not be dissapointed!

Rick, you are up really early!!!!

[size=12]Well. You could weld it shut. BUT, you will encounter much longer warm-ups. It will take longer to evacuate the crankcase of moisture, volatiles and particles at start-up. It will take longer for the oil to warm up. You'll be using more gas as the mixture will need to stay richer longer. You'll be sitting longer waiting on that warm-up while the motor wears out a tad faster and your wallet empties a bit faster. That's my long view.[/size][/b]

I did a little memory exploring after our conversation Rick, I think that I have my heat riser in the wrong position! I can't wait until I get how to see if my memory serves me well. I'll take a picture and post.

[size=12]Sounds exactly like fuel is boiling, developing excessive pressure which is forcing fuel past the metering rod.[/size][/b]

Hey scoutpilot - you may be right about the heat riser. I will check the fuction of the riser tonight. The intake is new from Walks but that doesn't mean the riser is not getting stuck in the open position allowing heat to rise. Last night after driving around for 30 minutes I parked the jeep and noticed a gas smell. The fuel filter was only half full of gas and when I took the horn off the top of the carb., there was gas dripping out of the nozzle in the throat of the carb. I noticed that after a few minutes the gas level in the A/C fuel filter would fluctuate up and down and after about 30 minutes the glass bowl was full and the dripping stopped from the nozzle.

Does this sound like boiling? Also I have noticed that the carb, and horn gets pretty hot and I don 't think it should be that way.

[size=12]The lack of the plate is allowing more heat from the exhaust than you want to reach the carb. This makes the fuel in the carb bowl boil. I know it's a PIA, but you'll have to fix the heat riser. Sorry buddy.  :'([/size][/b]

Tumbleweed,
Yes, I am still having the issue with my jeep being hard to start.  With Scoutpilot's help, I have been working through a number of issues.  This weekend, I just finished up installing heat sleeves over all my fuel line from the tank all the way to the pump and then up to the carb.  I am planning on some test runs this week (low 90s here this week).

Scout,
Not sure if I mentioned this or not, but my heat riser plate was removed before I bought the jeep.  The rod, spring and weight are all there, but the plate was drilled out and removed........long ago by the looks of it.

MACRISEL, are you still experiencing hard to start after running for a while? I am experiencing a similar issue currently. Yesterday after I ran about 45 minutes and shut the engine off. I opened the hood and my glass bowl filter was only 1/2 full. I wonder if I have another minor issue???? My fuel line routing is similar to yours. I have insulated all the fuel lines from the pump to the gas tank.

 I was stumbling around HD for a tool and figured I'd take a peak down that isle.  My wife had a hard time understanding why I was so excited about a goofy little brass fitting. :)  I bought 3.

Thanks for the info Tim. I think I've been to every shop in the Greater-Bangor area looking for one of those...except Home Depot, of course.
