Re: Marine Cat 3116 priming issue

There are plastic check valves in the inlet and outlet of the transfer pump, a check valve in the transfer pump piston, and a pressure regulator under the return line fitting. You need to inspect all of them.

Marine Cat 3116 priming issue

Hello there!

 

I have odd problem with one marine Cat 3116 engine,which is now in the workshop,rebuilt,but parts like governor are old.

 

An they were sitting more then a year now..Problem is,that i cant prime the fuel with hand pump which is on fuel filter,

 

i have fuel jerry can,transparent fuel line to inlet,but it doesnt take one drop of it. I have check thin small valves in fuel lines,

 

they are not stucked or nothing,but still,problem is there..

 

Can somebody give me some advice on this strange issue? 

 

Much obliged!
