Re: Fuel Pump Check Valve.

Jay, Depending on which fuel pump you have. The Bosch catalog shows 
the De Lorean to use a 0-580-254-984, this has a long neck and has 
the check valve built into it. The pump that I sell and just about 
everyone uses is the same # except the last three digits is 957. This 
957 pump has a shorter neck as shown on my web site. The check valve 
is just screwed on and easily replaced. Unless I'm misintrepeting 
something it's that easy. A real simple test is to take it off hold a 
air hose on it and try to open it. I turn the air tank pressure down 
to 40 to 50 lb's. I will post a long neck on the site in a few days 
to show the difference. Could you have a lower pressure pump.
