Hi. Corrosion on fuel lines advisory on MOT from last year. Its the last thing on that list now after a 4 year project to get M533 VBV back on the road.

Can anybody tell me part numbers for replacements/ recommend where to buy please? 

That will just leave the power hood and 28 years of dings and a couple of dents.

Hello Mark,

I think you are going to struggle to find a genuine replacement pipe for this 28 year old car. 
My suggestion is to get one made up in a copper based material  - similar to that used on brake pipes. You might have to put a join in it at some point, for convenience of fitting. Obviously use the old one as a pattern. 
Kind regards,

Gareth. 

Thanks Gareth, will update next week, fingers crossed
