Hey, sure i can post it. I am passing the post office later and can ask them to price it. It's not very heavy overall.
PS I also have ANOTHER original e46 m3 fuelpump that doesnt work.... i cant recall exactly what was wrong with it but it kept tripping my fuel relay. Smokey, if you or anyone else is interested in it for spare parts, the harness itself is probably ok (i assume it was the fuel pump itself that was coming to end of life). I bought a brand new one from BMW for c. 400 pounds.
edit: postage is per €9 (not signed)/€13 (signed post) per pump... or for both €11 (not signed)/€15 (signed post)
