Hello all, Haven't been on for awhile. A while back I had trouble with one of my ss16 twin's fuel pump. I took off the tank,stripped all of the fuel line from the tank to the firewall. Up under the seat deck where no one would go I found what I figured was another filter and couldn't figure out why they would have put one there. I replaced the fuel line and pulse type pump and now after it sets for a few days the engine won't start. No fuel. Now I am wondering if that "filter" wasn't actually a check valve to keep the fuel from running back into the tank. Does this make sense to any of you? If so can anyone tell me where I might purchase one? Thanks in advance. This is a great site with lots of helpful members.

If it was a check valve, someone added it, I don't think they came with one. I read somewhere one time to use the small diameter fuel filters with the Onan engines. I don't know if there is a specific reason, or just somebodies own idea. I use regular large diameter in line fuel filters and haven't had an issue.

I've never seen a check valve, but it sounds like a good idea. I do have 2 thoughts tho.

You could PM member BHTS and see if he has stock on them.

Or put a manual shutoff valve near the carb where you can get to it without opening the hood. Anywhere in the line should do it.

If you get a part number for a inline check valve I would like to try on my 318 . I was thinking on trying this , used on snowmobiles , but didn't want to dig into the tank , Al

Im pretty sure the factory pump has a built in check valve to prevent backflow of fuel.
