Bleeding The Fuel System...is there a better way?
I just finished winterizing my 2002 1GM10 Yanmar Diesel (that runs on
a Menger 19' Cat boat) and think there must be a better way of bleeding the fuel system. For the past three seasons I have changed the water seperator and paper filter on the engine at the end of every season. Then I begin the huge task of pumping the Raycor water seperator for the next hour until fuel starts flowing into the engine. After that I start pumping the lever on the oil pump (1 hour). Once I get fuel into the lines the rest of the bleeding goes very easy. My hand afterwards is sore and battered! I have tried cranking the engine for short bursts with the compression lever up (this does not seem to help). Is there anyway to prime or help this process along the way? |

I have a pair of 2GM20's which should be very similar to the 1GM. Bleeding never
takes more the a few minutes. If the lever on the fuel pump doesn't work, it means the cam that normally drives it from inside the engine is not lined up. It you turn the engine over a bit (rotate the pulley a few inches) it should then work a lot better. "Chris Butler" wrote in message om...

Are you (can you) prefill the new filter with Diesel before reinstalling it?
Otherwise I agree to install an electric fuel pump if it's that much of a chore. -- Keith __ "People who say you're just as old as you feel are all wrong, fortunately." - Russell Baker "Chris Butler" wrote in message om...

Try filling the cup on the racor before you re-install it. That is all I
have ever had to do for it. Same with the filter on the engine, but it still takes some pumping. I know you will probably spill some diesel fuel, but if you're careful you should be able to contain it. "Chris Butler" wrote in message om... (Chris Butler) wrote in message . com...

My issue is that fuel will pump but it seems to take forever. I have tried turning the engine to get a point where the lever on the oil pump will provide greater range. I 'seem' to find that....it still takes forever. Thanks Chris |

If you don't care for the smell of diesel , use ATF (the red stuff)
to fill your filters and bowls. Dump what's left from a quart into your fuel tank. Injectors love it. -- Scott Vernon Plowville Pa _/)__/)_/)_ "Jim Lea" wrote in message ...

Chris, Install a electric fuel pump. You will never go back. Chuck

Install a 12v DC fuel pump at the outlet of the tank and BEFORE the
filter set. When you need to bleed just turn on the 12v pump and sequentually bleed everything until you reach the guard filter on the engine. Such 12v pumps are arranged with diaphragm valves and will add NO extra differential pressure requirements to the fuel system when not operating .... they just sit there until needed. BTW - be sure to specify a 12v pump that has EPDM (ethylenePropyleneDiamineMonomer) gaskets and O-ring which are compatible with diesel fuel.
