This custom adapter is designed to mate the Metco Motorsports billet fuel rail kit (PN MFRS1000) with the factory fuel feed line. It is designed for users of the Metco rails who wish to maintain the stock-style fuel lines and the returnless design of the factory fuel system.

This convenient adapter uses extreme-pressure reinforced rubber hose that is multi-fuel compatible. A 180* AN adapter is clamped at the fuel rail end, and a precision-machined billet aluminum adapter (Metco Motorsports PN MFF0007) mates with the Ford outlet at the opposite end. Also included but not shown is an 8AN O-ring adapter that fits the fuel rail with the appropriate 6AN male fitting for the 180* hose end.

This adapter makes the installation of the Metco Motorsports billet fuel rails quick and easy.

Metco Motorsports Valve Cover Breather

 2003-2004 Mustang Cobra, 2007 & Newer Shelby GT500, Mercury Marauder

An Original Metco Motorsports Design!

This valve cover breather assembly replaces the original oil fill cap found on the driver's side valve cover on the supercharged Cobra and Shelby GT500 applications.

The base of the breather is CNC-machined from billet aluminum for a precise fit, and the included silicone O-ring is specially designed to prevent seepage at the base of the filter.  The filter base is microfinished for surface protection and good looks, and is easily hand-polished to a mirror-like appearance.  The removeable filter element is a high-quality reusable unit from S & B Filters, and the filter is securely retained to the filter base by a specially-machined retention groove in the top of the filter base.

The purpose of this valve cover breather is to vent unwanted accumulation of pressure in the crankcase, and to provide maximum circulation of ambient air in the crankcase to reduce oil temperatures.  The installation of this breather will contribute to increased engine oil life and reduce the possibility of failed engine seals resulting from excessive crankcase pressure.  This breather will reduce the effectiveness of the vehicle's PCV system, and it is not emissions-legal.

Note 1:  This breather will not fit the New Edge Mach 1 4V application due to inadequate hood clearance.

Note 2:

  This breather stand is also available with a male #10AN connection at the top instead of the provision for the breather element.  This configuration is designed for use in a custom crankcase evacuation system or for use with a vacuum pump.  Please see PN MBR0004-10AN listed elsewhere in this section.

2007 & Newer Shelby GT500

For Shelby GT500 owners who must remove the Metco Motorsports two-piece supercharger pulley from their GT500, this special tool is available.  The design of the supercharger snout in the GT500 application makes it impossible to remove the hub using a standard pulley removal & installation tool, but this specially-designed tool makes the process quick and easy. 

The simple design of the tool allows the user to remove the press-on steel pulley hub from the supercharger shaft without damage to the hub or to the supercharger case.  The end of the center bolt is centered on the end of the supercharger shaft, and the included five bolts are threaded through the tool and into the supercharger pulley hub.  A wrench is used to hold the hex on the hub portion of the tool, and a second wrench is used to turn the center bolt, drawing the pulley hub off the shaft.  The tool is machined from the highest quality materials and can be re-used many times.

Kit includes center bolt, pulley flange, and (5) bolts.

This custom adapter is part of the Metco Motorsports fuel rail adapter kit (PN MFRS2000) used with Metco fuel rails.  This is the billet fitting that mates the high-pressure hose of the MFRS2000 to the factory fuel feed line.

This adapter is CNC-machined from 6061 aluminum and has a barbed end on one side for the high-pressure hose of your choice, and the opposite end is configured to mate with the original fuel feed line.

We offer this adapter separately from the MFRS2000 assembly for users wishing to design a custom fuel system for their vehicle.

If your 2007-2012 GT500 is equipped with our popular 2.60" supercharger pulley upgrade, you may add this stock-appearing pulley cover for a stealthy look.  This cover is precision-machined from billet aluminum and then black-anodized, and it simply slides over the 2.60" pulley.  The cover is secured using a stainless steel socket-head fastener (provided) that threads into the hole at the end of the supercharger shaft. .

*Please note that this pulley cover is only compatible with Metco Motorsports 2.60" supercharger pulleys manufactured after Novermber 2012.  If you have doubts about compatibility with your pulley, measure your pulley ring and its widest point (just forward of the belt surface) to confirm an OD of 69.5mm.  If your pulley measures 72mm, it is the earlier design and this cover will not fit.

These pulley rings are designed for use with Metco Motorsports two-piece supercharger pulleys.  If you already have a Metco supercharger pulley on your GT500, one of these rings is all that is needed to change the boost level on your vehicle.  These pulley rings will bolt to your existing pulley hub using the same (5) fasteners, and no special tools are required for the change.

Our pulley rings are precision-machined from billet aluminum and then black anodized for long lasting surface protection. 

Listed below are approximate boost gains that can be expected when installing these pulleys on a Shelby GT500:

MSPR3.00: Stock diameter, no change  MSPR2.80:  +2-3 lbs  MSPR2.60:  +3-4.5 lbs

We recommend the use of our Auxiliary Idler Kit with the 2.60" supercharger pulley to maximize belt wrap and to minimize belt slippage.  Our idler kits are listed elsewhere in this section.  

Kit includes (1) pulley ring.  Please make your selection above.

This is the same pulley hub included with the Metco Motorsports supercharger pulley kits (MSP2.60, MSP2.70, MSP2.80, & MSP3.00) listed in this section.

This kit includes the CNC-machined pulley ring mounting hub and five stainless steel hub-to-pulley ring fasteners with lockwashers.  The pulley hub is nickel-plated for long lasting surface protection.

This pulley hub is compatible with any of the Metco Motorsports GT500 pulley rings listed in this section.

Note:  One competitor offers a 'Metco style' supercharger pulley hub with a relaxed interference fit to save time during installation.  Please note that the genuine Metco pulley hub is precision-machined for the appropriate fit on the shaft necessary to resist the high loads imparted by the supercharger belt in the GT500 application.
