<p>I covered one of the fittings with a balloon (party balloon), plugged all other ports and pressurized the tank a bit, just so the balloon would inflate. I left it like that overnight to see if the balloon would deflate (you have to figure how to measure the balloon size before and after).</p>
<p></p>
<p>The obvious advantage is that there is no mess, no smell and no risk of combustion - and air is less viscose that water or gasoline, so it is more likely to "find" smaller orifices.</p>

<p>I guess I am still confused. Where does the solvent come into play? Is it to check for leaks, cleaning the tank, or something else?</p>

Damon is right.... I pressure tested (extremely low psi). Then let it set overnight with solvent. Now is the best time to check your fuel senders for accuracy. Set the angle of the tank to match wing angle an check. Ajust the float level if nessary. Now is the best time to get the sender right

<p>I am not to the point of testing my fuel tank, but I thought tanks were pressure tested with air or nitrogen and soap solution to to indicate where any leaks are.</p>

I used solvent. Gas is fine too, just be careful.
