Overview:

Holley Fuel Cell EFI Pump Modules with dual VR Series Brushless Fuel Pumps. These drop in modules come with two controllers and harnesses to give you VR fuel pump power inside your fuel cell. While the name includes EFI, these modules can be used as an upgrade for carbureted systems as well with the proper regulator. The modules were designed to drop in as a direct replacement for your existing 6 bolt flange fuel cell cap assembly. The billet top flange includes an 8AN inlet port, a 10AN outlet port, and a fuel filler cap. The fuel pump depth is fully adjustable from 7.5" to 11" deep. The module kits include all the hardware to install into your existing fuel cell. All that you need to add is your fuel line. ***Assembly fits common RJS, Jaz, Summit, Jegs, RCI, Speedmaster and Speedway fuel cells. Designed to work on high boosted race cars as well as your daily driven weekend endurance car, these pumps work with gasoline, methanol, and E-85* (Compatible for methanol and E85 for competitive drag race use only- when draining and flushing after each race event) and can maintain pressures of 130 PSI and up to 335 GPH flow**. Fueled by TI Automotive. The pumps include a 2 step controller for pump speed control. The pumps can be ran in one of two different speeds. A low speed control for low fuel consumption requirements or at full speed for high fuel consumption requirements. The VR2 includes (2) controllers for precise control of both pumps independently of each other. Both the VR1 and VR2 pumps are proven for 18.5V compatibility. **At 13.8V * Overall pump dimensions: 9.5" Long; 4.75" Wide; 2.75" Tall

Features:

  • Capable of 130 PSI while providing significant flow for forced induction applications where belt driven pumps are normally used.
  • Unlike other pumps, the VR Series are built for continuous duty if needed.
  • Billet aluminum construction for durability and good looks
  • Designed to drop right into your existing 6 bolt flange fuel cell
  • High flow and high pressure with low amperage draw
  • Can be fully submerged in the fuel cell or chassis mounted

Efird, a great product
Size: 8 Fl Oz (Pack of 1)
Used this in a Troy Built Garden Tiller, the tiller would stall and hard to crank until we use the Sta Bil Fast Fix, tiller now runs great and does not stall.

Worked great, saved me hundreds.
Size: 8 Fl Oz (Pack of 1)
I've had issues with the carburetor on my 2003 Honda ATV for years. It has needed cleaned regularly to stay running, and one repair shop wanted over $400 to replace the carburetor. One treatment with STA-BIL and it's running smooth again. Very impressive.

Great for 2 cycle, meh for 4 cycle.
Size: 8 Fl Oz (Pack of 1)
This stuff is flat out amazing for 2 cycle small engines, works like advertised. 4 cycle isn't as good, if your engine hasn't ran in years, you'll still have to clean the carb, but it does help some. The 2 cycle oil for one is a lubricant and inhibits varnish buildup (especially a synthetic premium brand), and usually premium oil has a fuel stabilizer in it. Plus if you don't have a float bowl, there's not enough fuel for phase separation. I also use it in my mix for my ultrasonic cleaner when cleaning carbs. Overall a very good product, but understand it's limitations in this modern age of ethanal fuel.

It works well.
Size: 8 Fl Oz (Pack of 1)
Great product that delivers on what it says it does. This won’t fix a mechanical problem or damaged component, but it will fix a stuck float, varnished tank, gummed up jet, or partially blocked emulsion tube.

It Works
Size: 8 Fl Oz (Pack of 2)
This stuff works. I added it to my four 5 gallon gas cans before filling them up. I’ve used 10 gallons of gas in my lawn tractor so far and can tell it likes it. I do annual maintenance before summer and check or change the spark plug so it performs the best it can. I have 508 hours on it and with this it seems like it idols smoother, which indicates it has helped in the carburetor since I haven’t had to remove it and clean it. Works great.
