97 fuel pump HELP!

My pump has a flying saucer looking diaphragm on top of the fuel pump and the copper oring is bad. I know i need to replace the entire diaphragm but what is it exactly called? :dunno: i need to know so i can order it! haha... also, i've been told that i should just upgrade the entire fuel pump to one from a 99 because it doesn't have this diaphragm. anyone heard of this or done it??

The Diaphram (look like star ship enterprise) is a pulse dampener. Your truck is a CA model truck...It has split shot injectors which require a pulse dampener on the pump to dampen the fuel pulses of the mechanical lift pump.

In order to upgrade to a 99+ electric pump you will also need to replace the filtration system. Many have done this by gathering their own parts but there are also kits out there such as one you can find at Beans Diesel Performance

Hope that helps!
