Sorry that email was just to use this site when AOL became unsupported. Cardone sells a repurposed slightly larger unit that works. Sellers on eBay or Kirbanperformance.com. About $200. But your symptoms are not perse accumulator though that may be weak too. Pump running repeatedly is usually check valve or can be internal leak in master ( less likely). Discharge unit key off 10 pedal applications and disconnectt the pressure line entering side of MC. Use a small easy out to pull out the check valve seat assy and spring with poppet. Clean and if needed the plastic poppet can be refaced gently with a sheet of 1500 wet on a glass or granite surface. Very lightly and at 90 to the surface reface the poppet with a few circular actions. Is all the air bled out? If foaming the volume will drop as foam settles and cause pump to run again. Or a spec of dirt can cause leak down. They all had no leak down on test jig. Weak accumulator is usually "runs with pedal apply" or just one apply. With a fresh accumulator you should get 2 applies then run.

Ok that is a slightly different symptom description than the original. You need an accumulator, but we knew that. That should fix it.

Is the pedal set to fully unload not applied? Just looking for an explanation for the occasional running. New accumulator typically has pump start during 3rd apply. So you get 2 normal stops on just stored accumulator pressure.
