Fuel pressure regulator/check valve for all 6.5 trucks, all years, Including all C/K trucks, G/P trucks, Suburbans, Tahoe's Yukon's, Van's, School buses and Hummer H1's. Fits and is correct for all DB2 and DS4 pumps, mechanical or electronic injection. On the 6.5 injection pump the regulator is built inside the return line fitting. It maintains the required 3-5 psi fuel pressure. It also acts as a check valve to prevent the reverse flow of fuel to the tank while the engine if off. If your fuel pressure is low, it may be a bad regulator valve. Symptoms of low pressure are stalling, hard starting, and a hesitation or stumble on acceleration. To check your pressure use our test gauge ssd-242 or permanently mount our ssd-215 gauge kit. Installs in minutes with basic hand tools. Also fits all 6.2 diesels too!
