Been there!Done that! The more you drive it the better it should run!Many times leaks are from overtightening fittings etc.

Well, I ran it yesterday around the nieghborhood and no problems. Today I went a little further(still staying on the backroads, though) and actually stopped at the gas station, put gas in and left, drove around a little further and seems to be running fine. Of course, when I get back I check to make sure nothing is leaking. Maybe soon I will have the courage to actually get in trafffic and stop at a (gasp) red light! I know you guys have probably all been there too, thanks for the help.

You could have crud inside the float bowl which is floating around jamming up the needle and seat.Also a good opportunity to check the float level.

Sorry, no. You have to pull it apart to clean out float bowl and blow air through. If it was a fresh rebuild you should be able to reuse all the parts.

Well, I got the new fuel tank installed and fuel pump installed, blew out old fuel line with compressed air, installed new fuel filter, put gas in tank and it started up and seemed to run fine until today when I tried going up the street and it stalled out on me. Looked under the hood and gas was again pouring from the carb. Waited a little while and it started back up, got it back to the house and let it run awhile with no flooding. Took it down the road again a couple of times and ran fine. Could it be I still have crud floating in the carb bowl or is it a float problem? I'm not looking forward to taking the carb apart, is there any way to clean without disassembly? The carb has been rebuilt, but my biggest mistake was running it with that 50 year old fuel tank I guess.

Well, in doing some checking, I was able to find a new fuel tank from LMC for about 200.00, and a new fuel pump for 50.00. The  fuel tank cleaning and sealing kit would end up costing at least 75.00 itself, plus all the mess and hassle of doing the job. I've even seen videos of people putting rocks in the tank and chains to loosen up the crud. Does not look fun. I'm getting too old for that crap, so I'm going with the new tank and pump.

The fact that you are seeing crud in the filter is again likely the reason why the carb is acting up.Crud gets into the inlet needle and it cant control fuel bowl level.You may also need to replace the steel line from tank to carb as it may be corroded inside.By the way ifyou do drain and remove tank please be careful.An empty tank is worse than a full one as the fumes are extremley flammable.

To really clean the tank, what I've done in the past is to drain it the best you can and then pull it out of the truck. Take it to a radiator shop for cleaning. There are some companies that make a fuel tank coating if you or the shop think it needs it. I think the Eastwood Company and POR-15 both make fuel tank sealing kits. If the tank is badly rusted, you may want to consider replacing that too.

Rono.

I am seeing some black crud in the filter, I guess the best thing is to drain the fuel tank and clean it out. What is the best way to clean these tanks?
