I'd probably just rebuild that one if I were you. Wolfsburg West sells good diaphragms, with material from Effbe: https://www.wolfsburgwest.com/cart/DetailsList.cfm?ID=113127141WW

The only difference between type 1 and type 3 pumps of this era is the spring size. Type 3 had a slightly thicker spring for higher fuel pressure. You could always swap over your original spring, although if you measure the fuel pressure and it's within spec, I wouldn't bother.
