Black version of
SP228The "'flip top' and 'push button' opening cap was made famous by some of the most historic cars ever raced at such famous tracks as 'Monza' and 'LeMans'. The design was conceived for function not looks- it allowed the racer to fill the gas tank faster.
The actual cap screws onto a special brass adapter that is a tight press fit onto the neck of the tank but should be glued for safety.
To fit the collar for this cap you will require 10mm(0.3937")just over 3/8" of petrol tank neck accessable above the body seal to allow fitment, many later cars do not have this much neck protruding so check first.
Neck size 2 1/4"(57mm).
The slimmer mpi seal may aid fitting
WGG100010.
If you require a cap that takes the genuine locking cap see
SP227.
This cap does not accept a locking cap.
