    Questions about Riva injectors 50lb, all my head broke, help please

    I put the injectors Riva 50 lb on the stand and saw that they only work at a pressure of 2.5 atmospheres and up to 3.2!!!

    with increasing pressure to 48-58 psi they simply do not work! under a pressure of 3.2 atmosphere waterfront performance their injectors 10 percent more than the stock injectors!

    I can not start the engine with them! put native stock injectors easily run!

    What is the secret?

    Yours

    riva are delphi/lucas and they're garbage but that still wouldn't be the injector. Maybe your fuel pump is giving out

    The Riva/Delphi injectors do not operate well at higher than stock fuel pressures. Here is the solution
