Free the tube joint clip while sliding the fuel tube joint from the fuel suction plate plug until no additional foreign substances remain while avoiding damage on any part. Perform the tube removal by hand using only your fingers instead of tools while preventing forced bending, twisting, or turning of the nylon tube. You should place protective tape and a plastic bag over the tube after cutting the main fuel tank tube loose. Take out the two bolts securing the fuel tank protector plate before moving on to the six bolts on the fuel tank vent tube set plate and ending with the removal of the fuel suction with pump and gauge tube from the fuel tank while avoiding damage to the fuel pump filter and ensuring the fuel sender gauge arm remains unbent. Finish the process by taking out the gasket from the fuel suction tube with pump and gauge tube.
