I havve heard that the 1993 fuel pumps are better because of increased capicity. I have an oppertunity to buy one for $100 but am not sure if it will fit my 1999 6.5TD.

1999 K3500 6.5TD

 

It will fit and if it is AC Delco it is the best stock lift pump you can buy for your truck.

Avoid parts store LP's-AC Delco/Delphi or high end aftermarket like FASS or Airdog only.

 

Thanks a lot. I am no sure what make it is from the photo but for the price i think it will be a worthwile extra part to clean up and keep around.

 

Shop around,Rock Auto shows the 93 Delphi LP #HFP905 for $59.11 Canadian.

 

Thats just the pump. this guy is selling the whole assembly. are the assemblies interchangeable between the 1993 and 1999?

 

Ok are you talking about the lift pump or the injection pump?

If the injection pump then there is a great deal of difference between a 93 and 99 injection pump and they are not directly interchangeable and the 93 does not have increased capacity.

 

My mistake. I heard a lift pump or H/D unit from a 1993 would be a good mod. Then I got things twisted in my head.

 

Your pictures won't expand for me to get a good look.

The lift pump from rock auto is the mod you were told about and might need.

The injection pump as I said can be done but is not easy nor a benefit other than you won't ever have to worry about a PMD again.

Supposedly the 93 LP is Better. They look the same to me.
I run an Airdog. Some guys use the Walbro.
