[Shotimes] Help with Fuel system problem.

[Kevin & Cheryl Airth]

Don:
 The problem is in the fuel check valve in the fuel pump. You get a new one
when you change the pump. I don't know where to get just the check valve. I
am sure the car has enough miles to justify a new pump. I like this guy for
cheap hi-output pumps:
