Pressure testing the fuel tanks

20 Aug 2004 Pressure testing the fuel tanks

The QB tanks come tested from the factory, so the only thing that needs to be tested is the stuff that I added to the tanks. In my case, that would be a return fuel line, the fuel level senders, and the tank covers. In one tank, where I started to install a flop tube, I cut an extra hole for the fuel level sender which I got to plug up.

Here is the right tank under pressure (about 2 PSI):

Here is the left tank under pressure. Notice that I never removed this tank from the wing. The rubber glove can be replaced with a standard balloon if you have one available.

I’m very happy to say that the tanks held pressure nicely. I hope to never see any nasty blue fuel stains on my tanks!
