Fuel Fill Drop Tube for Diesel Generator
Features
- Can be used with the 5-gal spill box
- The drop tube delivers fuel within 6-in of the bottom of the tank, resulting in submerged filling; this increases the fuel delivery flow rate and reduces vapors, foam, and potential tank evaporation
- Threads directly into the existing fuel fill NPT port
- Compatible with all Generac Protector series diesel generators
- A powder coat painted, steel fuel fill drop tube is required in some municipalities to prevent sparking due to static electricity build-up, which can be caused by the fuel dropping into the tank from the fill area
- Easy installation
- Fill Drop Tube

Generac 6507 – Frequently Asked Questions
1) Will the Generac 6507 fuel fill drop tube fit my Protector series diesel generator?
Yes. The 6507 drop tube is compatible with all Generac Protector series diesel generators. It threads directly into the existing fuel fill NPT port on the tank, so no drilling or tank modification is involved.
2) Why would a generator need a fuel fill drop tube instead of just filling the tank at the port?
Two reasons. The 6507 tube carries fuel to within 6 inches of the tank bottom, so filling happens below the fuel surface. Submerged filling raises the delivery flow rate and cuts down on vapors, foam, and evaporation out of the tank. The second reason is code: some municipalities require a powder coat painted steel drop tube to prevent static electricity build-up and sparking caused by fuel free-falling from the fill area into the tank.
3) Does the Generac 6507 drop tube work with a 5 gallon spill box?
It does. The 6507 is made to be used together with the 5-gal spill box, so you can run spill containment at the fill point and still get submerged filling from the drop tube.
4) What is the Generac 6507 made of, and does it need painting or coating in the field?
It is a steel drop tube that comes powder coat painted from the factory. That coated steel construction is exactly what jurisdictions asking for a spark-resistant fill arrangement are looking for, so nothing needs to be added to it on site.
5) Will a fuel fill drop tube help with foaming and slow fill on a diesel generator tank?
That is what it is for. Free-falling fuel into an air space aerates the diesel, which causes foam and can trip a nozzle early. The 6507 puts the discharge within 6 inches of the tank bottom so the fill stays submerged, which speeds the delivery flow rate and reduces foam and vapor.
6) Is installing a Generac fuel fill drop tube an electrician job or can maintenance staff do it?
It is a straightforward threaded install. The 6507 screws into the fuel fill NPT port already on the tank, so facility maintenance or a fuel service tech can handle it without cutting into the tank or touching the generator's electrical side.
7) What is the Generac part number for the diesel generator fill drop tube, and where is it made?
The part is Generac 6507, sold under that same manufacturer number. Country of origin is Mexico, and there are no shipping restrictions on it.
