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

Necessary for travel
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Purple
This is really cute and looks classy. Quality is very nice. The only thing is the hooks for the necklaces didn’t keep them on, but everything else about this is a must for traveling and not losing or tangling up your jewelry.

LOVE IT!
Size: Large (8.2"W*4.2"D*2.4"H), Color: Beige
I love it. It’s very pretty and simple, in a good way. I plan to use it for all my jewelry and not just for travel. I like that it has a lot of hooks for necklaces and plenty of space for earring and rings. The fabric inside and out seem to be good quality. It’s well made and zips easily. The structure is sturdy as well. The color (white) is just as depicted. I think I got the larger size but it doesn’t feel bulky at all. I like that it comes with an extra pouch for bulkier items. It’s one of the best jewelry boxes I’ve had!

Nice little travel solution for jewelry
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Pink
Cute travel box for my jewelry. The necklace hangers aren’t all that snug, causing my necklaces to fall and tangle some. But otherwise, works as expected.
