: check valve nut sizes, 1988 9000 non-turb

24th September 2002, 09:45 AM

i am replacing the return check valve on a 1998 saab 9000 tonite for a friend. i forgot to check the size of the nuts where the new ck valve ***'y ties into the hard pipe fuel line just in front of the gas tank.

does anyone know how big these are? i have to pick up some flare wrenches on my way home.

also, anybody have any hints on breaking this connection free? i usually use the blue wrench (torch) but i know better than to use it on a gas line...and these are brass fittings, so i don't want to round 'em off.


please email me if you know!
