Abstract: Various plastic structures for automotive applications are disclosed. The plastic structures are preferably produced by blow molding and comprise at least one cavity, generally for containing a vehicle component therein, formed within the confines of the wall structure. Exemplary applications of the plastic structures include various fluid reservoirs located in the engine compartment (e.g. along the fender inner panel, the wheel well liner, the underside of the hood, the cowl, the firewall, and the front-end structure), the passenger compartment (e.g. rear shelf, door arrangements), beneath the vehicle (e.g. fuel tanks, spare tire holders) and alongside the vehicle (e.g. step platforms).

Abstract: A fuel tank has a delivery unit which is arranged within the tank body and which has a reservoir. The delivery unit can be introduced into the tank body through a closable opening in the wall thereof. The tank further includes a filling level measuring device which is arranged outside the reservoir of the delivery unit and which can also be introduced into the tank body through the opening. The measuring device can be introduced into the tank body separately from the delivery unit and is held in its operative position by a holder mounted to the opening. The holder can be in the form of a ring mounted to the edge of the opening.

Abstract: A fuel tank for a motor vehicle, comprising a tank body with a smaller reservoir which is arranged therein and which is inserted into the tank body through a closable opening in the wall thereof, and joined thereto. The reservoir is deformable at least in portions of the wall defining same. After the reservoir has been at least partially inserted into the tank body, it undergoes a change in shape resulting in an increase in its volume within the tank body and a change in its cross-section such that the largest cross-section of the reservoir is larger than the cross-section of the opening of the wall in the tank body, that is available for insertion of the reservoir. The reservoir is defined at its ends by rigid components and the deformable wall portion of the reservoir is in the region between those components.
