The other day I was showing a friend my razors alky kit and showed him how the test button works. Then proceed to show him under the hood and he notices that my pump is leaking. I have never had this issue before and I did check to see if all my fighting were still tight. The leek seams to be only on the pressure side since it takes longer to see a change in my wideband after its sit for some time vs. test it, then ten minutes later test again with the test button. Any ideas bad pump, failed seals? The kit is 2 years old and used every day, about 55 gallons a year.:biggrin:
