Got a new Drake steel tank, fuel line & rebuilt carb; car ran fine for about 65 miles after sitting for about 5 weeks, now am experiencing same problems again. Moss Motors has an interesting article on ethanol; here's what I learned: In a open fuel system like we have in our old Fords shelf life is about 35-40 days because ethanol based fuels absorb moisture up to 50 times greater than the standard gas resulting in "phase seperation," water in the fuel. There's a laundry list of other bad things it does also. Fuel stabilizers help but not completely. Wish I would have got a fiberglass tank & not worried about authenticity. Who's got the parts for an ethanol proof carb?

Flatbob, Most carburetor kits sold today have alcohol resistant parts. Describe your symptoms again in this post, there may be an easier way to solve your problem. It may not even be fuel related. I have been using gasoline with ethanol added since the middle 1990s in my car, and add Stabil when the car is going to sit more than 30 days. I have had no problems with the car running due to this gas.

More than likely, you are getting "wet" fuel from a service station. While gasohol is "hydroscopic" and attracts moisture, it is due to contamination during transportation and storage, in most cases. If you get a bad batch of gas, one remedy is the addition of "Heet" to the tank. It is methanol, rather than ethanol, and has "deiced" fuel for longer than I can remember. I'd buy my gas elsewhere. Some very old carb kits are not "fuel proof" with nitrile parts. Ask your supplier before you buy about this, because they are still being sold.

Tomo, thanks for responding; you helped me before with a very troubling fuel gauge problem. I let the car sit overnight & it started right up this morning. Anyway am going to get new parts for the carb that I know are better suited for today's gas. Thanks, Bob

Bob, I get my gas at a high volume station so I know the gas hasn't been sitting in their tanks for very long, will put some HEET in the tank also, maybe some STABIL also. thanks, Bob

In my opinion your problem is not due to the new metal tank or to the generic problem of new gas going bad in 5 weeks. I have several cars with stock tanks that regularly sit for five weeks or more. I try to get them all out at least once a month for a 20 mile run, but sometimes I don't get to it. At this rate I only add new gas about once every three to six months. I also look for an excuse to take a long run and use up most of a tank at least once a year. I have had trouble with three gas tanks this year, but they were all tanks in cars that had been left sitting with gas in them for more than 10 years. I agree that you may have gotten a bad batch of gas or, maybe, you have now run the car enough to cause another problem to surface. I'd take it from the top. Check the vacuum, the spark at each plug and look at the screen or bowl in your fuel pump -- or pull the top off of the carb to look for residual junk (e.g., a stray bit of gasket or sealer from the installation of your fuel pump sending unit). Good luck.

Deluxe 40, yes, am going to start with basic trouble shooting and see what the problem is. May not be bad gas as it fired right up the next day but wouldn't start later in the same day. Thanks, Bob

Through the years, I have found that 97.6% of all fuel problems are ignition (and vice-versa)
