Engine will not hold prime. After an oil change I would have to prime at a quarter tank all the time. After another oil change I would have to prime at 3 quarters of a tank. After replacing the fuel pump a line and the prime filter housing and all filters. I have to prime all the time? Any ideas?
Which series of L110? Sounds like you have a leak on the suction side. Does it start and then run out of fuel if you fail to pump the primer button?
If it has a Bosch in-line injection pump, take a look at the overflow valve.. it’s supposed to open up at 25 psi..
To help much further the letter postfix ( E , F , G or H ) and serial number will be required, as the variations are numerous.
