    The coupler is still absorbing vibrations, the switch fell out due to it being bumped. It’s in a pretty poor location without protection.

    I’m going to install a clamp over the switch so it won’t get damaged again.

    I agree a 2 stage will pull deeper more quickly, but I just wonder how much difference it would show in a real world test. It’s not like I’m going to buy a single stage.

    Problem solved!

    Just picked up a brand new in box, JB Eliminator 6cfm pump for $150 at a pawn shop. Didn't even have the oil opened yet. Tested it at. <19 microns.

    I have a 10 year old 5 cfm Platinum and the only thing I have had a problem with is the rubber legs. I just seem to keep loosing them. I can still pull down a system below 75 microns.

    I would buy another is a heartbeat.

    Just wish JB sold the oil in containers to match the capacity of each pump. When I fill with new oil sometimes it is hard to see when it is at the center line. I have overfilled many times and had to drain out some of the new oil. Maybe I need to pay more attention to what I am doing.
    Can someone please explain to me -
    Why is there never enough time to do it right the first time, but plenty of time to do it twice?

    I fill a container already marked with the correct amount for my pump then dump it in. Makes life so much easier.

    I have been meaning to do that for a long time. Just never on the top of my priority list.

    Will this intake cross fit the Eliminator. This is what my Platinum uses, with exception of the 1/2" port.

    https://www.ebay.com/itm/PR-76-J-B-I...-/162902401104

    Apparently the PR-24 has been discontinued. Anyone know where I can get one. I'd rather have two 3/8" ports than the 1/2" port.

    I guess if my Platinum fails, I can just take it off and install it on the Eliminator.

    How many of you carry two pumps on your truck?

    I used to carry 2 pumps. Now down to 1.

    I would call JB to see if that fitting would work on the Eliminator. I am sure they would give the best answer. I Have the Platinum on the truck, but an Eliminator in the shop as back up.

    I carry 2 pumps on the truck. Both are JB Platinums. The thread size that goes into the pump is 3/8 npt on both.

    As far as the eliminator series, I dont know, but I would assume 3/8 npt also. Just remove it and try to swap with the Platinum, that will tell you 100 percent.

    As far as wanting 2, 3/8 ports and a 1/4 cross.

    Just take the 1/2” port on the cross tee that is available, and install a 1/2” female x 3/8 male flare adaptor. Thats what I did when I was still using the appions.

    United or another refrigeration house should have them. And just leave it permanently installed, and get another 3/8 cap and you will be set.

    I have two JB's. I bought them years apart. One was new. One was used. I've rehabbed them both over the years, and both before they ever broke down. If you're making your living with a piece of equipment, in my opinion, cheap is not the way to go. BTW, most mechs I know never seem to be entirely comfortable when they have to drag out the cheap stuff in a pinch. Just my opinion.
