Just do like I do... Send it to pedro with some cash to rebuild your Fuel Pump. Pedro is one of the World's best resource for early Type-3s. There will be women who name their Children after him; besides his wife. Laughing

Excellent Tutorial Pedro... Topics like these, are the reason The Samba and Sambanistas are so great!

You mean the thread Tram started that became a Baywindow bus forum style yelling match about stock versus non-stock?

Finally got the pump rebuilt and it leaks gas out from between the diaphram and the two halves very bad. Dangerous to say the least. Pedro's write up said nothing about using gasket sealer (GasketCinch / Permatex / etc). Do I need to use some?

EDIT/UPDATE: Pedro just called me and confirmed that NO GASKET SEALANT is to be used. Also, he confirmed that the reason my pump was leaking is because I did not resurface the two halves of the pump. In his write-up he used a file to get them flat and shiny, I used a thick peice of glass and some 220 sand paper. Same results, and it worked well. Thanks Pedro!

The mating surfaces of the two pump halves can get a bit warped. Did you try to flatten them before reassembly?

Edit: it seems I was too slow. Glad you got it taken care of.
