Its a dedicated type 4 pump, so don't need any modification; I believe he even asked me what cam I ran because of clearance his designed my pump with
These are the same ones that were used in the old 'Käfer-Cup' W4 cars
.
TP stands for Thorsten Pieper, the builder of those.
Here's his 'profil' on the bug-talk forum:

This way you can send him a PM or email. His english is fine AFAIK.
Price is about half of the similar Remmele DS pump, but probably about
4 times the CB pump
Hope I have given you enough info
