I'm having some surging issues with my outboard and i know i need to look at the fuel system since i still have an old metal gas tank lol and i don't know how old the fuel line is so i'm looking at replacing the whole shabang at once. Would you guys go to a marine dealer to get a new tank, line, fittings and pump or will some of the stuff from wally world suffice?

Thanks!

Edit: it's just an older Evinrude 25hp tiller handle, no fancy gas/oil mixer whachamacallit.
