We are expecting our first batch of rebuild kits by the end of December, 2018. If interested, please contact GMG to get on the list. We had to source this from Europe. Bosch no longer makes this pump (as of 2017), so rebuilding is the primary solution at this point. GMG has been unable to find NOS (new old stock) supply of any kind for over 5 years. GMG will also be offering rebuild services through our partnership with a Bosch certified diesel shop that understands our generator applications. Please contact GMG for rebuild services.
