If the spring is weak, it could be allowing the fuel pressure to drop during extended periods of shutdown.

with the VW, theres no way of tracking down an OE...I'll see how much the lines would cost for the MB.
Are we talking the check valve on the MB or the VW? The VW has a "rebuilt" Bosch VE pump. The PO said it's a fresh rebuild from some shop in CA, but according to him the "new" tires were good (they were heat stamped....they're 14 years old and dry rotted)
