<p>Well I went out to the garage this morning and still had 1.5 psi in the tanks. I will have 60 gal in the wings and a small header tank, so I have 2 more to make. My theory is, you can never have too much fuel..... unless your on fire.</p>

<p>Jesse,</p>
<p>Looks like you've got a good set of tanks! However, the next most-frequent source of leaks are around the fuel sender gaskets. When I mounted my wings, I left the top skins off between the tanks and the fuselage and painted them separately. Then, when the plane was fully assembled, I filled the tanks with 100LL (the blue dye makes a great leak detector!) and let it sit for a few days to be absolutely sure there would be no leaks! Only then did I install the top skins and just…</p>

<p>Looks like nice work! For my pressure test I used a schrader valve fitting to pressurize the tank and a rubber glove sealed over the fuel cap inlet as a pressure relief and indicator. The glove stayed inflated (with a subjective firmness) for 24 hours - I considered that good to go. My tanks were built by Zenith and were previously pressure tested by them.</p>
