Guest Tusler 49 New Yorker Posted August 27, 2014 Share Posted August 27, 2014 On my new fuel pump it has a round canister screwed into the outlet side of the pump. What does this canister do?My old pump had a plug screwed in that spot.thanks Link to comment Share on other sites More sharing options...
