Brian,

Performing a CSV pressure test with the engine installed for ‘81~’83 SC’s is not as easy compared to ‘80 SC’s and earlier models because of the metal fuel lines. Those CIS engines particularly ‘80 and earlier models have flexible plastic fuel lines and easy to move the CSV with the fuel line connected. You can not do this with the metal fuel lines.

So to be able to do a visual CSV flow test for your late SC with metal fuel lines, you need a special fuel hose to be able to test it. Unless you have a CIS bench tester. Removing the CSV with the engine installed is not that convenient because of its location but you can remove the CSV without removing the engine. A partial drop will help access the CSV. Once you are able to get the CSV off from its mounting by removing the two (2) Allen bolts, connect the CSV with an extension fuel line back.

I will post a picture of the extension fuel line I built to do the test or you could improvise. The key is to be able to put the CSV in a container to collect and observe the fuel delivery of the CSV.

Do a mock up operation for removing the CSV and visualize the things you need to get the job done. For example, do you need additional space for access? What tools do you need? Is it doable at the current set up? How was this done by others? These are some of the things you should be aware off.

You have not done this before and could intimidate you. It is not difficult by very tedious and cumbersome to get the CSV off and test it. Don’t get frustrated or discouraged at the very beginning. It is doable and you will succeed if you think you could do it. I have more tips to share with you.
