Hi guys, so I bought my 94 355 a few months ago and drove well. After the third drive I noticed it started to have fuel starvation and the higher revs and by the time I drove home it got worse even on lower revs. A Quick Look on the forum and everyone seemed to have this problem that the rubber gaskets disintegrate. Removed both pumps and that’s exactly what I found. Now my question is, what parts would I need to re kit them ? is it just the rubber parts that need changing or is there something else ? Ofcourse I’m changing the filters and possibly the fuel lines too. Any links to best parts sites ? Attached photos of the pumps once out thanks Mauro Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
Looks like a giant rabbit hole... One of many threads on pump replacement/overhaul https://www.ferrarichat.com/forum/threads/fuel-pump-rebuild-fuel-line-replacement-5k-in-parts.662321/ https://www.ferrarichat.com/forum/threads/fuel-pump-replacement.616651/ (F348) https://www.ferrarichat.com/forum/posts/148702324/ Where are you located?

The little covers for the wires I couldnt find them when I did this on my single pump 355. I have a set of the dual pumps came out of a parts car I bought it was a California car, I'd sell these if you're interested in them. Image Unavailable, Please Login
im from Malta and coincidentally, the rubbers melted as soon as I gave the car fuel for the first time in Malta.
I guess Eurospares UK or Maranello Spares would be good sources of parts, but you may have to get the big rubber boot from Ricambi USA. They have a fuel resistant boot which will last much longer than the original.
