Brand New Heavy Duty ACDelco Supply/Lift pump for all 6.5 Turbo-Diesels years 92-2002 installed in C/K pick-up's, Subs, tahoes and all vans . This pump is a perfect fit and will restore the necessary  fuel pressure to the Injection Pump. This is the correct pump for your diesel, NOT an "also fit". Includes the correct harness connector to just "plug-in". Will not fit H1 Hummers. For H1 Hummers, us p/n ssd-4222

The supply pump or lift pump as it's called is a booster pump that takes fuel from the tank and sends it to the injection pump. The injection pump needs to be fed 3-5 psi of pressure to work properly. If not, you will experience hard starting,  and a hesitation or "hiccup" as you accelerate quickly. Also check the oil pressure switch as that switch is what turns this pump on and off. Switch also sold on this website separately.

On C/K trucks and vans this pump is located under the truck, on the frame rail in the area under the drivers seat. Easily changed in minutes.

We recommend replacing the in-tank fuel strainer ssd-1702 (aka: "fuel sock") at this time. The OEM style strainer has a built-in bypass that opens when clogged allowing trash to suck into the pump, causing failure. The #1 cause of pump failure. This strainer should be replaced every 100K miles as routine maintenance.
