Gtsi Fuel Accumulator

Fuel should not exit via the vent tube on the bottom.

 

is this the definitive test on this part?

 

I believe that yes, fuel leaking woud indicate that the diaphragm is leaking and allowing both pressure loss (hard warm start) and fuel to leak from that little tube. Only fix is to replace.

See: http://www.ferrarichat.com/forum/mondial/424171-fuel-accumulator.html
for a brief confirmation.

 

One of the PO's of my car connected the vent tube back to the fuel tank breather! I believe it's there as a tell-tale for a faulty diaphragm

 

I've read that the US cars had that vent tube connected to the breather tubes as a safety feature to prevent spilling raw gasoline near hot engine components...

If you're looking to buy an accumulator, Bosch part number 0438170004 sells for $96.24 at Auto Parts at AutohausAZ - OEM Auto Parts - Discount Replacement Parts, Resources and Car Care Tips , list price $308. The best price I've seen so far, and I've bought several parts from them, they have been great so far to deal with.

 

If you need one I have a brand new one I didn't end up using I'll let go for a fair price pm me if your interested.

 

I believe all USA cars had that tube routed back into the tank. TAV11 on the 308QV USA clearly shows it. I don't know if ROW cars had that or not, but the Euro 308QV diagram on Ricambi's site does not show it.
