How do I fit a GAS IT 70mm Fillpoint body mount box?
If your a little unsure how the GAS IT black or white body mount fill boxes fits together with the brass bayonet fillpoint then attached here is a simple Tech sheet that we knocked together many years ago, on how to do it.
Before we go any further the fillpoint itself does not need to be higher than the tank as the fillpoint has a special one way non return valve in it but it is important that the pins on the fill gun side is horizontal.
We also have a quick video on the GAS IT youtube site that clarifies what to do which will work well with this document. ( https://www.youtube.com/watch?v=HRHNFvUvZXs )
Don't forget whatever you fit this body fill box to - the GAS IT body mount fill point box is a 70mm outside hole all the way through the body - EVERYTIME
Don't drill through the outside vehicle skin with anything bigger or smaller than 70mm as this is the size of the round fillbox. Anything bigger will not fit.
If your vehicle has a insulation section in the middle of the inner and outer skin then you need to drill a 70mm hole on the outside of the vehicle and a 86mm hole on the inner. It is important that you DO NOT drill a 86mm hole all the way through the vehicle as the fill boxes are 70mm round.
This 86mm hole will allow the fillbox to correctly grip the outer wall between the inner and outer box section. See attachment here for pictures showing you what you need to cut.
We sell 70mm and 86mm hole cutters with the correct harbors in a kit in our Install tool section of the GAS IT webshop. Click here for the tool section.
It's important to note that you must never mount the 70mm fillpoint box into the gas locker door or on any moving panel. This is because every time you open the door, or the panel moves, the fill hose will twist significantly and it will cause leaks on the joints between the fillpoint and the fill hose sooner rather than later.
If you are installing a 70mm body mount fillpoint or any part of it like the fill hose is within the living accommodation or habitational area of a vehicle you need to seal the rear of the fill box off with a fillbox angle or straight rubber boot. You also need to cover the fill hose with 30mm vent tubing and vent it externally via a 30mm floor vent. This make sure no gas from when filling or any leaking joint on the fill system goes into the habitational area and it is all vented downwards and out of the vehicle.
Here is a link to our webshop showing the 4 main vent items needed when fitting our 70mm body mount box in a habitational area. Click the relevant item below to be taken to our webshop.
3) 70mm angle rubber boot for use when angled fillpoint is used
or
4) 70mm straight rubber boot for use when straight fillpoint is used
Also see our attached fillpoint location document that shows you that you should keep the fillpoint away from windows, 240 volt points and exhausts to name just a few. It also shows you the required safety distances from these point and vehicle features.
