No, not really - IIRC the seal seats against a recess in the oil pump cover, but to be sure, look closely at the seal depth and the relationship between the seal and the outer edge of the oil pump housing before you remove the old seal. If there's no seat for the seal just drive it in to the same depth as the original one. Go carefully and a little at a time all around the seal housing until it's where you want it. Once it's started I find a large socket or a big fat drift pin and a tiny hammer does the job (a little at a time.

Before you install the new seal, examine the crank nose area where the seal lip makes contact and be sure there's not a groove. If there is one large enough to catch a fingernail, you'll need a speedi-sleeve. Likely it's fine.

Coat the seal lip and crankshaft nose with a light smear of multi-purpose chassis grease or assembly lube before you install the seal.

Good luck,
Frank
