HO16-108 - HOLLEY HYDRAMAT RECT 8"X3"

8" x 3" Rectangle, Center Pick-Up With 3/8" NPT Female Fitting

Part Number: HO16-108

The amazing HydraMat™ is Holley’s patent pending design that solves the problems associated with traditional fuel pick-ups in stock fuel tanks as well as racing fuel cells. During hard cornering, acceleration, stopping, inclines, and low fuel conditions fuel runs away from the fuel pick up which introduces air into the system resulting in poor engine performance and even stalling. HydraMat is the solution!
Surface tension and fluid wicking are the secrets of the HydraMat, giving it the amazing ability to draw from nearly any area that has contact with fuel and then store it in its internal reservoir. As an area of the HydraMat is uncovered, the tiny pores of the media seal off through surface tension, forcing fuel to be contained in the reservoir and drawn from other areas of the mat where fuel continues to be available. The sheer size and coverage area of the HydraMat allows it to pull fuel from virtually any area in the tank or cell eliminating the need for specialty reservoirs and pick up pumps saving cost and greatly reducing complexity.
Features:
Patent pending design that solves the problems associated with traditional fuel pick-ups in stock fuel tanks as well as racing fuel cells
Greatly reduces the potential for air to enter into the fuel system which can result in poor engine performance and/or engine stalling
Perfect for vehicles experiencing fuel starvation during hard cornering, acceleration, stopping, inclines, and low fuel conditions
Surface tension and fluid wicking allow the HydraMat™ to continue to draw fuel from the tank or cell even when part of the mat uncovered
As an area of the HydraMat™ is uncovered, tiny pores in the media seal off through surface tension, forcing fuel to be drawn from other areas of the mat where fuel continues to be available
Unique internal reservoir assists in keeping fuel available at the pickup even under extreme fuel slosh conditions
Eliminates the need for specialty reservoirs, sumps and pick up pumps saving cost and greatly reducing complexity
Also acts as a 15 micron pre-filter eliminating the need for a separate filter before the fuel pump
Can be folded and compressed for easy installation through a variety of fuel cell openings
HydraMats™ are also available in other sizes and shapes to fit a variety of stock fuel tanks and/or race fuel cells
Works with Alcohol, Ethanol, Methanol, and E-85 fuels
Not for use with oils or diesel fuels

Good fitting support !
Size: Medium, Color: White
Just what the man needed. Very good contoured support. No jostling. Not a loose potato sack after an hour of wearing this. Highly recommended. Compare? Hanes, for example. Even the Jockey brand. Put those on, they're tight fitting, seemingly supportive. But they're not. They aren't contoured to fit. That's the whole idea. Contoured, to fit. And stay fitted. The trunk type, just like this wirarpa, and in half an hour it's loose loose loose fitting. A potato sack. No support. No support at all. That's not what a trunk brief is supposed to do. It's supposed to support, give comfort and confidence, stay in place feeling. Assuredness. And this wirarpa Mens Trunk does the job ! Wash and wear and wash and wear. Stays in shape, never gets stretched out and loose, for the fit.

Comfortable & well-fitting, but some differences in stiffness between batches
Size: Medium, Color: Black/Deep Blue/Deep Grey/Heather Grey
I've basically been exclusively buying these since I've discovered them. Super-comfortable and maintain their shape for a long time, but I've noticed from buying it multiple times that sometimes the pouch area has stiffer texture and more support than other times (when it's loose & stretchy like the rest of it). I wish I could specify receiving the more-supported ones because they tend to produce less....how to say, knocking the boys around.

Look great, feel great
Size: Large, Color: Black
These feel great and fit well. With most briefs I tend to the trouble either keeping the front in or not having the back cover everything but these do both things and are very soft. They also look great, even on body types not in the promo picture. They are a great set of briefs and have held up so far and I got mine a little around a year ago and wear them often.
