Bleeding 2GM20

[valhalla360]

OK, changed out a clogged filter and had to figure out how to bleed the system.

I'm a big guy and in a tight space, I can't get my head around the side of the engine to see. I've got the manual and looked up pictures online. For the life of me, I can't find the little lever on the fuel pump to prime the system.

Finally in frustration, I closed the water supply (so exhaust water doesn't back up into the engine). Opened the first bleed screw and cranked the engine. 3 times at 10sec each and got fuel coming out, did the second with 1 time at 10sec and as soon as diesel started coming out the engine also came to life.

I was at dock with shore power, so I wasn't too worried about running the batteries down.

For future reference: I'm just wondering if there is any harm in doing it this way?

That's the way I do it.....using the starter.

When I change the primary filter, I fill it with diesel before putting the new one on, hence, don't have to bleed. I haven't changed a secondary filter for a long time, but would certainly try it the same way.

I've used the little lever on the pump, the starter, and an auxiliary electric fuel pump added to the fuel system, they all work but the starter and electric work the best. You have to go by feel to find the manual lever and even after you've just used it is hard to find again.

I use the starter too, with raw water off and decompression levers open (less load on the starter that way. The little lever barely fills the primary filter after a minute of pumping. Using the starter is Far easier. I also have a squeeze bulb before the lift pump.

On Yanmars I just use the starter and bleed at the injectors. They seem to start right up no matter what you do!

Easiest and preferred by me with your precautions performed!

Kinda like "parking" back in high school...
