I have finally gotten a clean fuel tank on my pony that I purchased at Dale Lawrence's Auction. But the fuel bowls I have are leaky and leak my $4 gas out onto the floor. I was going to order a new one but there seems to be two different bowls. I sold the tractor that the tank came off of and I don't know the serial number off of that tractor. My current tractor falls under the later numbers. It's exact number is PGA 9733A. I also noticed that one costs around $20 and the other costs around $60. How do I figure out which one I need and can I get the expensive one (if that's the one I need) any cheaper?
