Lawn Mower Or Snow Blower Fuel Pump Inspections And Repairs. Your small engine’s fuel pump is used to help carry gas through the fuel line when the carburetor is higher than the gas tank, causing problems for effective gas transference. Most fuel pumps are made from plastic or metal, and they use the crankcase’s vacuum to develop pressure. When you want to inspect or repair the fuel pump, you would find it mounted on the carburetor, close to the fuel tank or in-between the carburetor and the tank. When you locate it, you can start your inspection by doing the following: – First, turn the fuel valve off at the base of the tank, where it is attached. If you don’t see any fuel valve, then use a fuel line clamp to stop the flow. – Now, loosen the mounting screws and remove the pump from the mounting bracket or the carburetor. – See if there are any hairline cracks or other damages on the outside of the pump. If your fuel pump is metal and has some sort of damage, you should get rid of it and replace it. Now we’re going to show you how to effectively repair a fuel pump in a lawn mower or snow blower. – Repair the mounted screws if the fuel valve is closed or if the line is clamped. – Use needle nose pliers to loosen the clips to disconnect the fuel hoses. – Remove the screws and take the pump apart. – See if there are cracks or damage on the body and clean the metal parts in all-purpose cleaner, for approximately 15 minutes. – See if there is any softening, hardening or cracking in the hoses and replace them if there are any faulty parts. – If your gaskets, diaphragms and springs are old, get rid of them and use parts from an original manufacturer’s repair kit to replace them.
