So, figuring the fuel line is alright...just ran the boat on the river. Had some problems with the brass fittings that I installed on the fuel pump leaking ever so slightly. The pump says "do not use teflon", some users on the forum say they don't use anything, and the guy at the auto parts store told me to use this "aviation" grade pipe thread sealant that's ok to use on fuel lines. I went with the aviation sealant...but probably didn't use enough as I was worried about clogging the pump or filter with anything.

Any tips to get these fittings to stop leaking?

I noticed the existing fuel pump that was replaced at the dealer a couple years ago actually has teflon (or some type of) tape on the exposed threads that you can see. Maybe I should have just taped my threads? Or does gasoline eat away at teflon and that's why it's not used.

Despite the leaks the boat ran like a champ and has never started so quickly when I turned the key...so I think the extra fuel pump is gonna make a real difference.

Thanks for any advice.
