Putting in a new kit, two questions. Number one. Original diaphragm. had a spring loaded seal. Looks like could’ve been leather. The kit only has a rubber cup with a hole in it for the plunger to go through. Is that just a newer way of doing the same thing? Number two. When reassembling should I use some type of sealant on the diaphragm or should it just tighten down and not leak. The surfaces appear pretty nice and if it needs sealant, what is the consensus for recommendation?
