Merc fuel coupler o-ring install

[eltoquad]

I’ve installed several o-rings in OMC fuel couplers but this Merc one has me stumped!!!! Have coupler apart but can not get inner o- ring into groove. Help!!

Mercury pressure fitting? Sure you have the correct size orings? Should be pretty straight forward.

That’s not the coupler. Getting o-ring into the twist lock part is the problem.

Elto,
I didn’t know those came apart. Maybe ask the question on the mercury website too. Lotsa guys over at that site would know.

Dave B will know, and he’ll probably respond here when he sees your post.

never had one apart. but I would heat when I remove the pieces. after I asseyears ago.mbled it I would use a set screw to keep it from coming apart. did it on an aftermarket that came apart

I found the answer!! The "groove" for O-ring isn’t actually a machined groove. Part is bored straight thru, then O-ring installed and a washer is pressed in to hold O-ring .
