The opening and closing of fuel injectors creates pressure pulses in the fuel rail; this can lead to unstable fuel pressure. In order to achieve a safe and consistent rail pressure, a fuel pulse damper (FPD) is often necessary. The FPD's internal diaphragm will absorb oscillating pulses and stabilize fuel pressure. This correction can be measured throughout the RPM range and can often help idle surge, especially with high flow injectors. Furthermore, a fuel pulse damper can help solve erratic lean air/fuel ratio spikes, commonly experienced as 'stumbling', that are difficult to tune out. 

Fuel pulse dampers can be mounted at any angle, including upside down. There are many variables that dictate if a fuel system requires fuel pulse dampers. For instance, there are cases where multiple dampers are necessary. There are also other times when the fuel system benefits with a fuel pulse damper on the return line.

Features
1. Male Fitting Selection:
a. The 8AN ORB versions seal using a FKM O-ring. 
b. The 3/8' NPT variations seal with the tapered pipe threads. 

2. Vacuum Port Orientation:
a. Because 20-0178 and 20-0179 use tapered threads (NPT), the vacuum port can be clocked to the desired location.
b. Even after tightened, the newest 8AN ORB dampers (20-0776 and 20-0777), will swivel permitting the vacuum port to be clocked 360 degrees.

Included

-Anodized and laser engraved aluminum top, R=range or XR=extra range
-Anodized aluminum body with male threads, 8AN ORB or 3/8" NPT
-Stainless steel hardware
-Rubber vacuum hose, 4mm ID
-Vacuum hose Y-fitting 

A 1-way check valve permits flow in 1 direction only. Radium Engineering check valves feature a lightweight anodized aluminum body with FKM seals and stainless steel hardware. 
The check valve is compatible in multiple applications including gasoline, ethanol, methanol, diesel, water, coolant, oil, etc.

The 6AN kit includes the 20-0534 check valve body but adds all the necessary adapter fittings to convert both the inlet and the outlet to 6AN male and/or 6AN female.

Need to install a 105mm rear main seal into a 991 or a 997.2 Porsche 911? Make sure you set the seal to the proper 7mm depth from the surface of the crank flange! If you install the seal without a tool that controls the depth, you'll likely install it too deep, and you'll have a high risk of a leaking seal.  It's simply too time consuming to do the job twice, so do it right the first time!

This is an affordable alternative to the costly (~$400) factory tool from Porsche. Simply bolt this tool to the crank using the flywheel bolts until the tool bottoms out on the crank. Remove the bolts, verify that your depth is even, and you're done!

This CAD designed tool is 3D printed plastic, and is safe to use on your seal without risk of damaging it or the bore that the seal sits in.

Break a shifter fork, gear, or have a beat up old transmission? Feel the way we do about the transmission that just broke in your Protege? Replace it with a good, used transmission, fully assembled and ready to drop in. These will fit any 2.0L FS-DE based Protege with a manual transmission.

Have a MazdaSpeed Protege or want to upgrade to a transmission with a limited slip differential? Upgrade to the MazdaSpeed transmission below (note: unless your car has ABS, you will need to install a speed sensor into the transmission).

Transmissions are shipped via freight and do not qualify for free shipping. Your order will ship when additional shipping fees are paid in full.

MazdaSpeed- Has limited slip. No speed sensor

With Speedsensor- Non ABS 

Without Speedsensor- Has ABS 

This Part Fits:

The V8RLS1 blockhugger header is fits Mazda Miata LS engine conversions and 1927-Up cars and trucks using GM LS engines.

This design places the driver's side collector slightly off center, and being only 7¾" from the center of the flange to the bottom of the collector provides ample room for the tightest fit in a variety of vehicle applications.

Works great with Flyin' Miata and similar conversions. You will likely need to create clearance in one of the runners to create room for the steering shaft.

Comes with all hardware necessary for installation.

OPTIONS:

Aluminized Ceramic Coating is available and RECOMMENDED on all Sanderson Headers. They apply a multi-layer inside and outside silver ceramic coating in-house to meet high standards of quality, and polish the coated header to a high luster. This coating provides aerospace and military technology to your vehicle to control the heat in your engine bay, improve cylinder scavenging of exhaust gases, and increase the longevity of your header investment.
