old snapper sr2130 gas cap vent screw

[B-Sonnier]

i lost the vent screw on the gas cap / gauge of my sr2130 snapper. The cap / level gauge works fine so i don't want to spend $30 for a new one and i like the fuel gauge so i don't want to buy a plain cap. was hoping its a standard screw but the parts lists don't show that part. It sits on top of the 7019377yp cap/gauge.

The more represent a banjo bolt. Hole through the middle with vent holes on the sides.
