Holley Double Pumper® carburetors are a perfect performance upgrade for hot street cars and race vehicles. Double Pumper carburetors are an American icon when it comes to performance carburetors. From their roots as the premier carburetor on many factory muscle cars to powering thousands of vehicles across the finish line, the Double Pumper is a great choice whether you are burning up the street or the quarter mile. The Double Pumper is designed for use on lightweight vehicles with a manual transmission or an automatic transmission with a high stall and low rear end gears. The Double Pumper is available in a gold dichromate or tumble polished shiny finish and features dual accelerator pumps for additional fuel under initial acceleration, mechanical secondaries for great performance, dual feed fuel inlets for constant high volume fuel delivery and an electric choke for easy control of engine warm up. Don't trust your performance to just anyone, Holley is the only modular carburetor company that has been in business for over 100 years and has powered every NASCAR champion since the 60's.

Notice - Due to the natural color variations of the dichromate plating process, the plating color may vary from casting to casting (within a carburetor) and from carburetor to carburetor. This is considered normal and is not a cosmetic defect. If you desire a carburetor with no color variation, please shop our black and shiny finish carburetors.

Mouth rinse that has no alcohol and works like no other I have experienced.
Flavor Name: Mint, Size: 33.8 Fl Oz (Pack of 1)
Biotene Oral Rinse mouthwash was the answer for a pre-rinse mouth wash, even before bed to leave my mouth sweet and moist. Instead of having to drink something or taste something - - - so I won't eat something before bed.
It's been a miracle answer for pre-bed and dry mouth during a sleep period and wakening dryer than I want to be. I used to use Biotene "dry mouth spray", now I don't have to because the Oral mouthwash is my go to! enough said!!

Great for chemo

I ended up ordering this due to hearing mouth sores occurring during chemo. Using it twice a day to keep from getting the sours and it’s working great.
