Yes marine. Here it is with the filter. Also I will get more real pics when I get home from work. Doesn't help I posted last night when it was dark.

Return the flame arrestor and get one with the dump tube ??? Here is one and I am sure there are plenty of others available. Just make sure to size it properly according to your engine power.

I didn't buy it. It's how I got the boat. I might just add a barb to my current arrestor. Shouldn't be that hard.

Ok. It has to dump the fuel directly into the carburetor. Not sure how the fitting goes through the screen part. Also go ahead and post a picture of your actual carburetor without the flame arrestor. I was looking and some of the older Holley marine carbs had a separate tube. Maybe the Quick Fuel one is like that.

Ok here's what I got. Looks like oil is comming from the fuel rupture line. Also looks like my primary have been sucking oil.

What is this black hose hooked up to ??

Pcv port on the bottom rear of the carb

Is there a pcv valve somewhere ? Normally the two hoses from the valve covers go to the flame arrestor like the picture in post #8
What is in your other valve cover ?
