Fuel restriction/leak down/high psi fuel related cummins tools

[joed2323]

Looking through cummins insite tests, I see they have tools for the high psi fuel pump test, high psi leak down test tool, fuel inlet restriction test tools.

The leak down test requires 5 isolation fittings.

My question is I priced these out from cummins and it comes out to be just over 1k in tools.

These "tools" are basically just isolation type fittings.

Does anyone know if they sell a kit somewhere with these fittings, might be cheaper then buying them individually from cummins, or can I find these fittings through a cheaper place??

I have insite but I do not have the proper tools to check the fuel system side
