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 1968-74 Corvette 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.

    34 DD approved
    Color: Dark Beige, Size: 34DD
    This is the first wired bra I’ve worn in years and also generally just my new favorite bra. I have breast hypertrophy and after 2 breast reductions and years of gravity, they’ll find a way to spill out of any cup and slip under any wire. The second I put this bra on I immediately felt weight off my back. The wires feel actually supportive instead of restrictive and my chest settled right into the cups smoothly and comfortably. As opposed to relying on padding (which makes me so sweaty), the construction and fabric do all the heavy lifting which makes me feel supported while still staying cool

    SO very comfortable and supportive, but can't get the four hooks hooked in the back.
    Color: Light Beige, Size: 44DD
    I measured myself as described in listing and ordered 44dd based on that. The bra fits just right. It is super smooth and soft fabric and VERY comfortable! I especially like that it holds in the side boobs and the underwire does not poke out. I don't think I have ever had a bra before that actually stayed up on the sides! Maybe I have been wearing the wrong size?? I was skeptical and bought because of the free returns, but I am keep this one and one other style which is just as comfortable. THE ONLY THING WRONG AND THEREFORE 4 STARS is that I cannot hook the backs (4 hooks). The other one I bought was doable but with effort, this on I absolutely could not do and had to hook in the front and slide around. I don't know if there a fix for this but I will keep them because they are so dang comfy and supportive. And yes, they do minimize which is also wonderful for me!

    Fits like a $100 bra
    Color: Black, Size: 36H
    I don’t know why HSIA bras are so comfortable. The underwire does not dig in. This is the third one I’ve purchased. This bra has a pretty lace pattern. I love it. Highly recommend.

    Great bra!
    Color: Dark Beige, Size: 38D
    I have several different bras from this brand. This is a really good minimizer. It has a nice wide strap. I don’t love the clasp as it is covered in a hard material, but overall it is a good bra that you can wear all day under form fitting shirts.

    Uncomfortable
    Color: Light Beige, Size: 38DD
    In my search for a comfortable well-fitting bra, I came across this one. Reviews were good, so I ordered one. Half way through the day, I had to take it off. This is the most uncomfortable bra ever. This one went on to the "uncomfortable pile" pretty quick Not full coverage and not supportive. Side coverage is pretty good but straps are thin and do not lift.
