Hello, I just changed a fuel pump on a John Deere L110 lawn tractor. I want to give the engine its best shot to fire up on the first dozen or so cranks. A fuel pump is used when the gas tank is mounted lower than the carburetor and gravity cannot be relied on to carry gas through the fuel line. Technoton DFM Differential-Flow Pulse-Out Meter for Engine Fuel Consumption Oilybits U. Gasoline and Diesel Fuel Injection:Operation,Diagnosis,and Service 671 as a safety feature. priming the fuel pumps for the first time Volvo Penta Fuel Pump Installation and Priming. If there's no primer pump, you just need to crank the engine to make the transfer pump work, or put a little air pressure in the fuel tank. The fuel priming thing is a pressure thing and not a time thing. Common applications include the transfer of diesel fuel between tanks, refuelling of tractors and earth moving equipment, the circulation or transfer of light weight oils, antifreeze, etc. Has anyone come up against this and does anyone have suggestions how to best do this - my thoughts are around syphoning fuel into the sedimenter / pump from a can of diesel and running the pump to get fuel around the system. This is called the pulse width.
