I'm in the market for opinions (lay, professional, heck even Billy Bobs) as to other possible causes BESIDES the fuel pump itself??? being the culprit. I dont want to run out and buy a new pump if thats NOT the problem grrrrrrrr
My Yamaha G14 Gas Golf Cart uses one of those 3 port (Pulse, In, Out) fuel pumps similar to those many small gas engines use that have the Pulse line to the engine crankcase so differing pressure operates the pump and its fairly new.......The suction line to the gas tank is new as well as the drop down line in the tank, i.e. no restrictions and no visible pin holes or other air/vacuum leaks........My new small in line filter is between pumps output and carb input NOT in suction line to tank.
EVERY NOW N THEN SHE STARVES OUT OF GAS (YES tanks full) and the small in line filter between pump and carb is bone dry and regardless of cranking and choking she fails to prime up n pump. HOWEVER if you remove the line from pumps output (to carb) and crank her over she eventually primes up n starts pumping gas out the pump, hook the line back up and the carb fills n youre off to the races. Still it kinda "spurts" the gas out, sure not any what Id call any steady "flow". The engine is low on compression and has some blow by if that matters all that much to those type of pumps???
Sooooooooo Ima thinkin hop on Flea Bay and just order a new pump unless someone has a better idea of another cause besides the pump??? NO IM NOT installing an elec pump. I may go out and pull the Pulse line to the crankcase to insure its okay but I doubt thats the problem.
problems problems lol when the grandkids come if that carts not up n running they may pop a cork !!!!!

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
