Oil Pressure Check Valve

[lynndiwagon]

I've had the same problem with my remote oil tank holding pressure as I have read about on this forum. I just returned from the Lake and noticed that after 3 months of setting the tank still had presssure. I think this is what is causing the BIG SMOKE problem when starting. The engine is a 1999, 135 HP, Mercury carb. model, sn OG804612. I have searched Mercury and other parts outlets for the part numbers for the check valves with no luck. Please help me find the part numbers and place to buy. Thanks. I have a book that shows the valves but not the part numbers. Thanks.

If the check valve you are looking for is the one in the block, that pressurizes the remote oil resevoir... The part # 21-878105-1
