Not exactly fitting in any of the other fuel system forums I think, so placing this here. My Commodore uses two Zenith INAT carbs, probably not used on any US Opels but problems are similar. They use as a sleeve for the acc.pumps the same material (is it really leather ?) in a little smaller diameter as the accelarator pump sleeve in the old Opel carb (Carter licensed one barrel) like the Olympia Rekords. Is there any material available to fabricate such sleeves by yourself or a large supplier who offers such sleeves as generic parts with specific measurements ?
Searched the German web, only found offers for complete pumps for around 80-90 EUROS per set http://www.ruddies-berlin.de/grafik/35inat_DB.gif (part no. 100 in this link)
