    I see no love for the YJ pumps.
    I have 3 6CFM YJ pumps with no complaints. The oldest is now 23 years old.
    I recently replaced the pump coupler on the oldest one to the current design.
    That’s about it.
    All 3 pumps pull down into the 20-30 micron range on a recovery jug.

    Itsiceman figured it out. You can get the part number from the repair parts breakdowns.

    Then just order the cartridge. Comes with new o-rings.

    And its way cheaper. Even if you dont want to hot rod the pump. You can get a new same cartridge and the pumps is literally new again.

    Its probably not much lighter. The motors are the same. The only difference is the size of the oil housing.

    I have found Zoro to be very reasonable in the pricing and availability of JB pump parts.

    I thought the 7 and 10 had a bigger HP motor?

    Dude this is awesome! Makes me want to buy another and hot rod my current one. It'd be cool as heck. Thanks for the tip on Zoro.

    Bet you could find a used JB cheap on Craigslist or Ebay, and so long as the motor is good, hot rod that.

    Pretty sure this is the 10 cfm cartridge, and be sure to get a shaft seal also.

    Just look at the parts breakdown. There like 3 bucks.

    Right on! That's cheap compared to a new pump.

    You can get the Navac 8 CFM pump (model without that useless built-in digital micron gauge)that includes a free trublu XL starter kit for a great price from trutechtools. Then don't forget to use one of the many trutech coupon codes and free shipping.

    I was going to upgrade my Jb platinum 7 CFM with the NAVAC deal.

    I am also going to try to modify my JB Platinum vacuum pump intake from the flared brass cross intake fittings to a KF-16 intake flange adapter so I can connect the trublu hose, or KF-16 tee, directly to the pump intake without using the 3/8” or 1/2” flare adapter to allow for increase flow like commercial vacuum pumps intakes are setup. I found a few adapters online to do the conversion but just need to verify the thread size on the pump.

    I’d be so happy if I can get a KF-16 intake to work on a residential size vacuum pump.
