Installation of Maintenance-Free Rentar Fuel Catalyst


The Rentar Fuel Catalyst reduces fuel costs by up to 12 percent and is guaranteed to pay for itself within a year in most cases — if it doesn’t, Rentar will refund the cost to you. It also reduces harmful greenhouse gas (GHG) emissions. The Rentar requires no maintenance, nor does the fuel catalyst have moving parts. Installation of Rentar Fuel Catalyst is straightforward and simple, but installing it correctly is critical to ensure the best results.

Installation Prep

Prior to installing the Rentar Fuel Catalysts, it is necessary to establish a baseline, put together a small kit composed of parts and tools, and sample the fittings and brackets.

Establishing the Baseline: Ensuring Your Guarantee While Conducting a Field Test for Rentar

Before all else, establish a liters/gallons-per-hour baseline of the engine in which you plan to install the fuel catalyst. Your baseline is of value to Rentar. By establishing a baseline and monitoring fuel savings — to make certain the Rentar pays for itself within a year — you will be conducting a field test for Rentar. Rentar can use your data and results to assess the efficacy of the catalyst.

Components of Kit

Suggested tools and parts for installation include:

•Rentar Fuel Catalyst

•rubberized C-clamp or another appropriate fastening device

•extended fuel line hose

•short fuel line hose (use a 90-degree elbow if appropriate).

•fittings and brackets

•hand tools you determine necessary

Sample Fittings

Sample fittings and bracket sizes before buying. Sampling fittings entail checking fittings against the diameter of the hose and the catalyst connections. Select brackets you can mount on the engine housing that will hold the catalyst in place securely.

6 Steps of Installation:


Step 1

Locating Fuel Line: To begin the installation, locate the fuel supply line. Close the fuel line valve; then remove the fuel supply line from the engine.

Step 2

Convenient Place: Using a rubber coated clamp — or two if they secure the catalyst more tightly — affix the Rentar Fuel Catalyst in a safe and convenient place on the engine housing.

Step 3

Longer Hose: Connect the new, longer fuel hose to the filter housing. The Rentar Fuel Catalyst is nondirectional, so you can connect the fuel line hose to either side of the catalyst.

Step 4

Filter to Catalyst: If convenient, use a 90-degree elbow to attach the opposing end of the new, long hose to the opposite side of the catalyst housing

Step 5

Short Hose to Engine: Attach the short hose to the entrance of the engine or fuel rail.

Step 6

Engine to Catalyst: Finally, attach the other end of the short hose to the fuel catalyst housing.

Keep the following in mind always:

•Install fuel catalyst as close as possible to the point of combustion, preferably no more than 6 inches away.

•Tighten fitting to 55-foot pounds of torque and use a rubber piece to buffer metal to metal contact.

•The inside diameter of the fittings should match the inside diameter of the fuel line.

•Completely remove plastic wrap and do not cover the copper cylinder.

•Do not install on the high-pressure side of the high-pressure pump

•Do not bend the short hose more than 30 degrees.

•Do not use any clamping device on the copper cylinder.
