After the pump has completed the test phase it is removed from the pump test stand and run on our oil flush bench to remove the test fluid (we started doing the oil flush around 02-03 time frame, don't really remember). If the pump does not pass these test points it is removed from the lot and repaired or the issue is resolved by replacing a component. On that record is the test for pump flow output, motor current draw, external leakage and relief valve opening pressure. Since January 06 these are built in lots 30-50 at time there is a lot number stamped on the banjo manifold that corresponds to the build. Back in the early days, each pump was run but no records were kept (I don't like paper work). I probably just got a bad pump.Īs strange as this may sound EVERY pump we build is run on a test stand for probably 10 to 15 minutes each. Soaked it for days in a tub of fuel, sprayed cleaner in the inlets and let it sit overnight, etc. I tried everything to "revive" that pump, short of disassembling it. So that "where they come up with this stuff". When I called Vans to ask (in 2006 or so) why my brand new pump (purchased in 2002 but never opened) did not work, these are the words they spoke to me. If this is the case you can send the pump back to us and we can try to fix the issue. If the pump does not run when voltage is applied the pump is either locked up (should pop the breaker) or it got varnish on the commutator from running the pump dry (causes an open circuit). Let it run about a gallon of fuel through before hooking up the system and putting pressure on it. This will allow the pump to pick up fuel faster as it will allow the pump to free flow. You should remove the hose going to the fuel control and put it into a container. The pump packages are oil flushed after we test them on the boost pump test stand. There are no "sensors" on this pump motor, or pump package. Believe me you can run the pump with no fuel in it until the motor burns up, or the pump element eats itself. I personally do not consider this a "feature". This is to prevent the pump from burning out if trying to pull from a dry tank. They are shipped (as I recall) with some fuel in them and caps over the fittings. The airflow performance pump has a sensor that will not run the pump if the inlet has no fuel.
