Loose fuel pump
Posted: Sat Jan 14, 2017 6:01 pm
Hi,
New to the forum. I've got a QB Kingfisher on my sailboat in Lake Victoria, Uganda.
I use it as an emergency kicker on my 9.7m Alpa sailboat.
It presently has a hard time running. One thing I've noticed is that the fuel pump mounting is very loose. I have removed the 'top' half of the pump, and found the screw inside that fastens it to the post on the engine. The screw seems to be seized, as I cannot remove it.
My questions:
- Is the pump supposed to be tightly attached to the body of the engine?
- How does the pump operate? If is pressure driven or mechanically driven? I cannot see anything that would physically move the diphragm (like a plunger).
All I know is that I get very little fuel flow thought it. That seems my starting point to no power on the engine.
Cheers
