Subject: Re: Anti Siphone Valve

The dealer gets his filter from Bosch. It is a simple deal with a paper filament and threaded fittings. Nothing special. No valve that I am aware of. The fueltank bulkhead for the fuel pump has a checkvalve to keep the line pressurized (at least on my 900 and 9k and it appears so in the EPC for the 2k 9^5). This may be weak or there may be a leak at the other end of the line on the fuel pressure regulator. Either way if it is not a prolonged cranking, it fires at 5-7 cranks, that will not stress the starter motor too much I would think. $0.02 KeithG Kristian Steve Jensen wrote: > "BL" <> skrev i melding > news:LRzjd.4415$ > >>I own a 2000 9-5 2.3LPT, and recently replaced the fuel filter with an OEM >>replacement ( not from the dealer).
