Howerton Equipped CTS-V Sets Record in Texas Mile

Here’s a few pictures of the setup.

BMW E39 Twin Tank Unit


Due to a few requests, we have adapted our popular twin tank unit to fit in the cubby area of the E39 BMW.  The unit features two 1 gallon tanks mounted to a power coated aluminum plate.  One tank  is baffled and feeds the pump, the other tank contains the level sensor.  The tanks are tied together with large diameter tubing to self level.
The unit drops in the cubby without any modifications.  We will be posting up more pictures as the first of these units are installed in cars.

Audi A4 B5


We recently had a call from a customer to install a system on his 99 Audi Wagon.  The customer was concerned about having a tank in the car, so it was decided a fuel cell would be appropriate for the use of the car and system.  So the car was dropped off and the install of an HFS-2 and fuel cell system began.  We discovered that most of the rear floor of the truck has the fuel tank under it, so drilling a number of holes for mounting the tank wasn’t the best idea, and there wasn’t time to remove everything to get the fuel tank dropped.  Therefore a aluminum brace that stretches across the car bolting to two anchor points was fabricated to hold the cell in the rear.  Below you will find a few pictures, with many more in the Audi section of the  Image Gallery.  The install turned out pretty well with the HFS-2 button in the switch panel of the dash.
