Just make sure it's a "new" diaphram made with modern materials...the old rubber doesn't like the E15 gas we get these days (which is most likely what did your existing pump in).

I have not heard or seen any rubber parts getting rotted out by E10-E15. Lots of stories that it COULD or MIGHT, but not a lot of photos of actual damaged parts. Now two cycle and marine engine.. yeah, cars, not really.
My 1944 dated NOS fuel pumps have had NOTHING in them but modern gas (E10) for the last 7 years... working fine.
And no, the white crust left by E10 fuel is ot much different than varnish left over from old gas... so at best its a tie.
