Fuel Tank Cap. Scepter/Neptune
This cap fits all the following tanks:
12 and 23 litre Neptune branded tanks.
12 litre Scepter branded tanks.
23 litre Scepter tanks sold by us from 2001.
Tanks prior to this had a guage built into the cap (our code for the cap/guage FU97). Either cap will fit the earlier tanks as the thread is identical.
