MAPed Blue Top Swap, NOT staying running! Please Help?!

The damper might be a Toyota specific part, so probably easier to
just try and find a washer. I don't have a pic just now, but consider
a standard round copper washer. On the outside it is smooth like a
regular washer.

On the inside circumference, parts are cut away to about half the
width of the washer, leaving around six "teeth" or posts that serve to
locate the washer on the centre bolt. Fuel passes up the outside of
the bolt thru the cutaways in the washer.

This is why if you put a plain washer in there, that fits close to the bolt,
fuel can't get thru. The toothed washer still seals, but around the outside
edge.

If push comes to shove, you can probably file some grooves in
the inside of a standard copper washer... enough to let a bit of fuel
thru and prove the point. A few 1 mm x 3 mm notches would be OK.
