Injector copper washers

I'm replacing my injectors. I also got an installation kit with return lines and copper washers. On the bottom of my new injectors are copper washers that fit tightly to the valve body below the nozzle cap nut. Are the copper washers in the installation kit redundant or are they in addition to the ones that come installed on the new Delphi injectors?

Thanks,

Tom

Save the ones in the kit, you will need them again.

When you use the ones in the kit, you need a dab of grease between the washer and the injector to keep them from falling off while you install the injector.

Thanks guys. The extras provided by Midwest Fuel Injection seemed to be redundant, but I've never done this before and wondered if the loose washers were to crush below the ones installed on the Delphi injectors since they were tight to the nozzle.

Hope to have this beast running tomorrow...

Thanks again,

T

Wow! I've got a new truck. Just replaced the injectors and injection pump along with the return lines and it goes like I put a turbo on it... ...well, in comparison to the way it ran before. And NO SMOKE! When I replaced the return line to the fuel filter I found that the fitting was too small for the return line hose; the previous owner or mechanic had used a plumbing hose clamp and cranked it down to 'fit'. I've got a pretty good idea that that's where most of the air infiltration was coming from. Still can't figure out where that fitting came from or why someone would have put it in. The exhaust smells like clean exhaust; no more burning eyes with unburned fuel blowing through the tailpipe. I've got the shop manuals, but wouldn't have gotten the job done without the input of your folks here.

Thanks to all for your help.
