The yellow XSPEC 30 litre diesel tank is mounted on XSPEC Window Utility Frame. These tanks come with an integrated funnel/spout/pourer in the cap. When the tank is sealed, the funnel points inside the tank. If you are pouring out fuel manually, the funnel is reversed and it gives you a funnel to go into the car filler neck.
WORD OF CAUTION: when the funnel is inside the tank make sure the funnel is flat against the opening and not at any angle, even a slight one. I recently had a small diesel leak out of my tank. I stopped and found a small amount of diesel across the back of the car, when doping a walk around. I thought the cap may have come loose, it was tight. Off I went.
I kept a close eye on the tank and it was leaking again. I stopped. The cap was not loose and everything looked sealed, until I undid the cap. When I did that, I could see the funnel was not flat against the container opening, leaving a very small gap in the rubber seal – the source of the leak. It was not visible until I undid the cap.
I am now sourcing a cap without a funnel to avoid this problem. XHQ are helping. I will put the funnel cap in the car if I need it - I normally use the electric fuel pump. This way I can always ensure a good seal when putting on the cap.
LESSON: check the car when you stop to find these issues early.
The red 20 litre XSPEC Petrol tank also has a reversible funnel.
