    I have a few new sets of injectors but am unsure of code. Read a few threads about harmonizing the injectors and got to thinking about different "pop" testing pressures and how it is common for the pressures to carry from one to the next in the same set. I'm always in a project or 5 so was wondering how hard it woyld be to fab a pop tester up. I'm sure someone has don this right?

    Or just buy one off Ebay. Only like $120, last I checked.
    They aren't the greatest(gauge may not be liquid-filled), but work fine. Remember that absolute pressure is less important than consistency, so if the gauge is 100 psi off, it won't make any difference.

    You will always re-time the engine when you put new injectors in anyway...
