(Universal M35)
If the fuel system needs bleeding (after filter change or perhaps after running the tank dry) how best to bleed air out?
Is there a "self-bleed return valve" or do you just open the fuel injectors?
Thanks!

Rick, I am sure there a lot of "bleeding" questions asked and answered on this message board as well as on the C36ia website technical notes.
Your M35 is "self bleeding" and there's a knurled knob on your injector pump. Never crack the injectors to bleed your engine.

I've found this to work every time. Leave the secondary filter on the engine just slightlly loose. Crank the engine and when it "coughs" as if it wants to start, stop, tighten the filter all the way, and start her up.
I know you don't want to crank the engine without it starting as it loads up water, but this will only take a few seconds ( I assume your pre-filling your filters before you replace them so you aren't trying to fill a dry filter).

Chuck, there's a NUT on the top of the secondary filter bracket to do exactly this thing. Tighten the sucker all the way and use the nut.
Also read the Westerbeke/Universal Bulletin about failing brackets and have it replaced.

Yeah I know about the nut but then you have to find the right socket. Since your replacing the filter anyway and it's loose, I find this simpler and faster.

Rick - I have the same identical engine. I have replaced all fuel filters at least twice so far and I have not had to bleed the air out. It starts just fine. Are you having problems or anticipating problems?

Haven't had a problem yet , but just wanted to ask the question.
Upon closer inspection, I did find the bleed valve on the fuel distributor part.
Also, when I first bought the boat, I changed both fuel filters. Not knowing any better, I quickly learned that with the pet-cock open, the primary fuel filter will fill up by gravity, then I tightened it at the last second. With a pre-filled secondary filter, the engine only took 4 seconds of cranking to deliver fuel to the cylinders and it started right up.
I was wondering about the "right way" to do it.
Thanks again, you guys are always helpful!
