Overview:

This in-tank fuel pump module is a high-pressure unit that flows 255 liters per hour (LPH) and is capable of supporting electronic fuel injection (EFI) engines producing up to 550 horsepower  A pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for this application is included  This module also features a HydraMat filter which has a unique internal reservoir that keeps fuel available at the pick-up and also provides protection from contaminates Fuel pressure is internally regulated to 58 psi eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator - no separate return line is required because this module returns excess fuel right inside the tank! This 1955-57 Chevrolet Muscle Car EFI Fuel Pump module was designed as a direct replacement for your factory pick-up and sending unit. There is no need to purchase a custom EFI fuel tank. You can even retain the factory fuel hard line - just connect the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps available in the Earls Vapor Guard line. This Muscle Car EFI Module includes a 255 LPH fuel pump and a Holley HydraMat. HydraMat is an amazing patent-pending fuel reservoir system that reduces fuel starvation issues that might otherwise occur while cornering, accelerating, stopping, traversing inclines, and during low fuel conditions.

    Definitely not worth the money you pay.
    Size: 14 Ounce (Pack of 1), Set name: Standard
    The dogs love them and they are great treats. The problem is for almost $20 a bag. You only get a fourth of the bag hole sweet potato strips. The rest of it is just the scraps from the skin. These get stuck in my dog’s gums and then their teeth and they’re hard to digest. I stopped buying them and went to another brand, unfortunately. I thought maybe it’s a fluke and the back got shook up, but I’ve ordered at least eight bags.

    First shipment was quality
    Size: 8 Ounce (Pack of 1), Set name: Standard
    Initial delivery was impressive. No odor no additives and longer pieces. Second bag was full of short, burned pieces. Expense would be worth it, if quality control existed.
