Anything less than what the owner’s manual says is a sign that your pump needs to be replaced or cleaned. The fuel will run to the engine through the hose or tube, and some rust particles can follow that same part.The regular cleaning process of the fuel tank will prevent carbon build-ups from rising to a higher level. I use the existing petrol cap which is usually enormously rusted too and it’s going to look like a new one (inside) as a nice bonus when the job is completed. During the drying process, you might just get a very tiny amount of tarnishing of the metal but nothing to worry about as sealing compounds will bond to this quite firmly and strongly. Step 9: Reconnect the connections and hoses of the fuel tank in place and make sure you closed the drain port of the fuel tank.

Be careful not to let anything metal touch it once it’s turned on either as it could cause an electrical short and start a fire. One gallon of Evapo-Rust can remove up to half a pound of rust, providing excellent value as it can be used multiple times until its potency fades.As rust builds up in your car’s engine, it increases pressure on components and causes them to wear out faster than they would if they were not being compromised by corrosion. Then re-fit the cap and rock the tank from end to end to fully mix the soda and water and disperse evenly.
