Try http://www1.mscdirect.com/cgi/nnsrhm and search for "raw materials,
rubber materials, sheet materials, neoprene" and pick a thickness and size

These guys aren't the cheapest, but they want to be your toolroom so they're
used to small quantities and deliver instantly, at least here in Southern
Indiana.

Last question and I'll leave you alone:
Where do I find sheets of neoprene as I was thinking of using engine
manifold gasket material.

I cut 8" square access ports to be sealed with 12" sheets of
Neoprene,
formagasket, aluminum sheets, and 8x32 screws.
Step1: Drill bolt holes in the 1ft square aluminum port covers. at
least 4 to a side equally spaced.
Step2: Center the port cover over the cutout, and center punch thru the
bolt holes for the tap drill. Mark a corner for reference, in case the
holes are not uniform.
Step3: Tapdrill, and tap. Note tapping aluminum sucks because it is so
soft the tap plugs up. BACKUP several times, and clean tap.
Step3: Clean all the shavings with a vacuum. (I am assuming you have a
clean dry tank here) Don't want them to look for your filter.
Step4: Lay the port cover over the neoprene, and mark for punching
holes. and punch.
Step5: Spread the formagasket around the port, 2" or more wide.
Step6: Lay neoprene over cutout, spread a 1/4" bead around each bolt
hole, and lay on the port cover.
Step6: Tighten all screws.
OOPS i forgot. The start of this was the fuel guage sender. You get the
idea. I would cut a hole in the port cover for it, and drill and tap
mounting holes. Of course do this before messing with formagasket.
Hope this helps.
