Hey, im working on a friends 2002 zr 800 and i noticed a puddle of gassy oil on the ground so i took off the fuel pump and its got a leaking gasket, are these gaskets sold seperatly or do i have to get a whole new fuel pump?

i just checked in my parts manual, it only shows the fuel pump as a full assembly. I was under the impression that these could be rebuilt.

Whole pump $42.00 new
