2. Please punctuate properly, folks Says: The BEST way is to remove the tank, empty it, and blow it out with a compressed air-line. Check it doesn't have any rust in it, if it does, add gravel and use a pressure-washer for 20 minutes, to get the gravel to scour it clean. Then use a fuel-tank sealer - key that in on eBay, all of them work well.

Change the rubber parts of your fuel lines, as pin-holes can be almost invisible. Blow compressed air through the metal fuel pipes, after disconnecting the other end. Refit with a new filter, and use ALL NEW clips. You will NEVER have another fuel-line problem with that car!

Anyway, if it has a carburetor, you will need to drop and flush the tank after all these years.

Then I would blow air backward through the lines, change the filter, rebuild or at least clean the carb, and you should be good.

have them perform a diagnosis of your lack of power or hesistation etc..

It's really the way to go.
