Overview:

The Holley "red and blue" electric fuel pumps have been the performance standard for decades. They continue to perform well, however, the evolution of fuel pump technology has surpassed them in quiet operation and fuel delivery capabilities that an in-tank module can deliver. Looking ahead to the future, Holley has designed their latest retrofit pump module especially for the carbureted applications. The module design is very similar to the existing EFI pump modules using a 255 LPH pump, but includes a built-in regulator for lower fuel pressure that carburetor applications require. Now you can convert your factory tank or fuel cell to an in-tank fuel system quickly and easily! The conversion is easily accomplished with basic tools and requires no welding or fabrication. The aluminum module design includes a die cast pump hanger bracket to control pump vibration while also providing a low profile design to fit where space is at a premium. Holley's innovative clamping system and integrated fuel pump makes it easy. Once installed, hook up your fuel lines and your power source/ground and you're off and running! NO hassle! An added bonus is that you can upgrade this module if you eventually change to an EFI system by changing the internal regulator. Supports up to 700 Carb HP (@ 6 PSI at 13.5 Volts / 10.4 AMP Draw) Of course there are many variables, estimates are based on gasoline. Individual systems will vary based on fuel system design, fuel cell location, etc...

Features:

  • The easiest way to convert your vehicle to an in-tank fuel system
  • Installs in any fuel tank from 6.5” to 12” deep to fit a wide variety of applications
  • The low profile design is only 1.275" thick above the tank mounting surface for added clearance when needed
  • The innovative clamping system allows you to locate the module anywhere in the tank beside your existing sending unit
  • The clamping system allows you to rotate the unit 360 degrees for easier clocking of the plumbing and wiring locations under your ride
  • Die cast aluminum construction for corrosion resistance and long lasting good looks
  • ¼” NPT ports for a wide variety of plumbing options

Glamorize your sunny day outing with this shimmer suntan protection
Color: Glistening Bronze, Color: Glistening Bronze
This body shimmer oil has a natural glow luminizer in it. It has an SPF of 45 for sun protection factor. This went on smoothly and easily and was light and did not feel greasy. It felt like fancy suntan lotion like no other I've ever tried before. This just adds a little glamor to your sunny day outing

Glowy, Lightweight Summer Shine
Color: Glistening Bronze, Color: Glistening Bronze
This gives a really pretty sun-kissed glow without feeling greasy or heavy on the skin. The shimmer is noticeable but not over-the-top, and it blends nicely for a smooth, radiant finish. I also like that it has SPF, which makes it perfect for everyday summer use.

This Oil Definitely Glitters!
Color: Glistening Bronze, Color: Glistening Bronze
I really wanted to love this shimmer oil, but it's unfortunately not my favorite. I love that it has SPF! That is a big win for me! The oil is also very good at hydrating my skin, which I appreciate. My problem comes with the shimmer of the product. The glitter in it is too big for my liking. With it being called a shimmer oil, I expected tiny glitter that softly shimmers like shimmer powders, lotions, and oils usually do. But this stuff glit-ters! And because it's bigger sized glitter, it's a lot easier to see when it gets all over everything like clothes, furniture, spouses and children. If the shimmering glitter in this was just smaller and softer, I would love this for summer time to use on my legs and arms. But it's unfortunately just not my favorite and I don't think I'll be using it anymore.
