Generac 6512 – Frequently Asked Questions

1) Will the Generac 6512 fuel cap fit my Protector series diesel generator?
Yes. The 6512 lockable fuel cap is compatible with all Generac Protector series diesel generators, and it was designed specifically for that series. If your unit is an air-cooled gas standby or a different Generac line, this is not the cap for it.
2) Does a padlock come with the Generac 6512 fuel cap, or do I supply my own?
You supply the padlock. The 6512 cap is built to accept a lock and fits most padlocks, but no lock is included, so add one to the order if you want the fuel system secured on day one.
3) Will a locking fuel cap actually stop fuel theft on a standby diesel generator?
That is the point of the 6512. Locking the cap closes off the fill opening so nobody can siphon the tank or drop contaminants in, which is the common problem on generators sitting on unattended pads, remote sites, and construction yards. It addresses tampering through the fill neck only, not the tank drain or fuel lines.
4) Is the Generac 6512 fuel cap metal or plastic?
Cast iron. That matters for an outdoor standby set, where a plastic cap is the first thing to crack or get cut off. Cast iron also gives the lock shackle hole something solid to sit in.
5) How hard is it to install the 6512 lockable cap, and do I need a technician?
It is a direct swap for the existing fuel cap on a Protector series diesel unit, no tools or fuel system work involved. Property maintenance staff can handle it. Shut the generator down and let the fill neck area stay clear of open flame while you make the change.
6) What part number do I order for the Generac Protector diesel locking fuel cap?
Generac part number 6512. That is the manufacturer part number to quote when standardizing locking caps across a fleet of Protector diesel units.
7) Are there shipping restrictions on the Generac 6512 fuel cap?
None. The 6512 cap carries no shipping or handling restrictions, so it moves as ordinary freight or parcel with the rest of an MRO order. It is manufactured in Mexico.
