I don't think '68s used this dual line fuel sender?..I do show it correct for your 69 application.
The #8846 didn't come until some time after 1974,to replace the original 1969 assembly line issued sender,which was part #6428322.
Call Craig Motors @ (707) 224-8111 in Napa, CA.,as he's showing an NOS one in inventory.
If you don't mind used that may still be accurate,aim for an old '69 or '70 Nova holding a 4bbl.<span style="text-decoration: underline">Hydraulic</span> lifter 350cid. or 396cid.,as they used the same one.
i.e...Not Solid Lifters.
