lucas cav fuel leak (with pic), any ideas?

[kingkongvs]

Hi guys, just got round to changing the cambelt, water pump and starter. I have a leak which is quite small at the minute (and has been for 10k miles) from the lucas cav fuel pump.

The leak collects just below and right of the blue sensor. Collects on the block. I have noticed you can buy seal kits, any ideas or common areas which will leak?

Been quoted 200 plus vat for a seal rebuild or 400 plus vat for a full rebuild. Are they taking the piss?

Cheers!
