Custom Tank Order Process

Step 1 – Your Drawing

All custom plastic tanks begin with a drawing, a template or an old metal tank that you bring along.

Your drawing or template doesn’t have to be perfect but the better it is the better we can help you. We realise not all of us are artists or have access to the latest computer drawing software.  A simple sketch showing the shape of the tank, its dimensions, the fitting locations and their sizes is all we need.

Take into consideration the height of the fittings, download the fittings guide to help you.

It would be great if you can measure your tank in millimetres as this is the most accurate method of measurement. All of our systems are in millimetres and nothing is lost in a conversion.

If you’re not comfortable in forwarding us a drawing, perhaps time is limited. Just download our quotation form and email it to us at This form will provide us with the most basic information that is required for us to quote.

Step 2 – Quotation

Once we have received your sketch giving the information that we need we will prepare and send you our quotation. If something doesn’t look right or we see something that may be beneficial to you we will contact you.

Step 3 – CAD Drawing

Upon receipt of your deposit, we then move to the next step and produce a CAD drawing of your tank. A copy of which will be sent to you. This is your opportunity to make any alterations, talk with our designers and check that all is well.

In peak times there may be a delay in preparing your drawing.

Step 4 – Production

When you are happy with everything and the drawing has been approved, we then move to the production stage. Your tank build will have been scheduled and an allocated build slot assigned.


Why not make a mock-up or a tank template it’s a good and quick way to see if your new tank will manoeuvre around any obstacles or tight spots that you may have, but more importantly, check whether you can get the tank into and out of the boat, vehicle or building. It is usually more expensive to modify a tank than to start all over again. Mark on the locations of any fittings and features such as fixing tabs.

Quite often customers send in or deliver their templates along with their sketches and we are often amazed by our customer’s ingenuity. Some of the templates that we have received are nothing short of a work of art.

NOTE: Plastic Fuel Tanks cannot be fitted in an engine compartment on a boat unless separated by a fireproof bulkhead.
