We do not sell a dedicated fuel line cleaner. Instead, you could spray Berryman B-12 Chemtool Carburetor, Choke & Throttle Body Cleaner (part #0117 & #0120) through the fuel line or use a high concentration of B-12 Chemtool Fuel System Cleaner (part #0116) in the gas tank.

Poured B12 into 2.5 gal of gas. Ran it through the tank and fuel system except the carb (Edelbrock 1406) into a bucket below on the ground till it ran clear. Had a bit of crud left in the lines wash out that would have ended up in the carb. Card needs some adjusting and fine tuning. I will keep you posted

Great...thanks!
