Pumpy the Younger

Another oil pump. Better version than the last one. This one should work with 3/4" PVC electrical conduit and female threaded adapters. Use conduit threaded adapters, the threads are not tapered in these as they are in water pipe. Regular water line PVC female threaded adapters work fine. Also this version only needs a cross hole to attach the piston to the end of the 1/4" rod.

You'll need:

3/4 PVC Shc 40
2x 3/4 Female threaded adapters
1/4" steel rod- ground or polished (Or 6mm if usin
