On some of the new engine kits I have installed there has been junk in the gas tank right from the factory....yes a shop vac can suck out loose stuff (obviously, as mentioned earlier, only do this BEFORE any gas has been used).

I typically go a step further though....I assume there may be loose stuff waiting to break loose so I will put some bb's ( or larger sling shot bearings) into the new tank and shake for awhile....You'd surprised how well this cleans up even surface rust in the tank...of course you have to thoroughly vac / clean out the tank afterwards....You can rest assured that there is nothing waiting to break free and plug up the in tank strainer.
