How it Works FAQs
We’re pleased to showcase the latest generation of GFS components that were designed and manufactured to our specific criteria. Many of these components were designed exclusively by GFS from the ground up for SVO, and the specific requirements that provide a trouble free experience.

1 ) GFS Adjustable Purge Controller
All GFS systems come with our 3V valve set and our adjustable quik purge capabilities. By controling our purge valve with GFS’s exclusive adjstable delay relay it allows you to fine tune your purge time for your specific vehicle.) The 3V assembly is controlled with a marine grade 3 position lighted switch. ON-OFF-Momentary. On for Vegetable oil, Off for diesel, and when you hit the momentary switch it triggers our exclusive GFS adjustable purge relay that flushes the engine with diesel and returns the vegetable oil to the appropriate tank. Once the purge is complete the light goes out, and you are on diesel.
2) 3V Triple Valve Set
Our popular GV 10 valve has been redesigned. All aluminum construction with banjo fittings all the way around. Now mounted on a sturdy stainless steel bracket with multiple mounting holes for easy installation. All valves come with a weather tight wiring harness with 10 foot lead wires. Each wiring harness has an LED at the valve so you can confirm that you have power to the valve. The heart of the New GFS system is the 3V Assembly. Our new 3 Valve assembly offers ultimate control of your return flow. Looped when on vegetable oil, Return to Vegetable oil tank for purge and return to the diesel tank when running diesel.
All systems come with a fuel level gauge and a vacuum gauge. The vacuum gauge lets you know the health of your filters.
4) Heat Exchanger
Our tig welded aluminum heat exchangers heat the fuel in the tank and also heat the fuel pickup so that even on the coldest of days your oil will flow unrestricted from the tank.
5) Trekker Tanks
Our tried and true Trekker tank Series is made from Cross linked polyethylene with UV inhibitors. Virtually indestructible. (See video) All aluminum heat exchanger with heated pick-up tube. Molded into the tank are threaded brass inserts for mounting filters, pumps, and whatever else your custom installation may require. Bolt don tabs are powder coated. Newly redesigned access ports will now support a filter bag. These tanks have a lifetime warranty.

6) Vented Fuel Cap
The 2″ vented fuel cap allows you easy access to fill your tank. The 40 and 60 gallon trekker tanks also have a 6″ cap which allows you a large access port to the inside of your tank.
7) Fuel Sending Unit
Our magnetic induction fuel senders are reliable and proven to work well with vegetable oil.
8) Lift Pump
For vehicles requiring an auxiliary lift pump we use a rugged gear pump designed for use with SVO.
9) Filter Heater Wrap
Our heater wraps have been redesigned with a lower amperage draw and when used with our exclusive filter insulators, provide ample heat to melt the contents of your filter even on the coldest of days.
10) SVO Fuel Filter
We use the best filter in the industry. Period. Filtration is all about surface area, and our filters have the most, by a long shot (click here for more information). Our heated filters are insulated with a custom fit neoprene insulator, which allows us to use a heater that draws half the amperage of other heaters with the same performance.
11) Filter Insulator
Conserving the precious amps your vehicle is producing, this filter insulator works in concert with your filter heater to insure a hot flowing filter.
12) 4B Hose
Our exclusive 4B hose provides a coolant loop to your in tank heat exchanger while keeping your vegetable oil supply line hot from the tank to the engine. Our exclusive hose consists of 2 – 1/2″ coolant lines, 1 – 3/8″ vegetable oil return hose and our exclusive 1 – 3/8″ clear view vegetable oil supply line. This Clear View hose is the first clear vegetable oil fuel line that can withstand any type of fuel, pressure and heat and still retain it’s elasticity in cold weather. This hose is an indispensable window into the flow of your fuel system and is an unparalleled educational and diagnostic tool. It allows you to visually confirm what fuel you’re running on along with diagnosing air leaks and fuel flow problems. This hose also includes 3 – 12 gauge wires for your pump, sending unit and filter heaters allowing you to connect your system components in one easy step. This fuel bundle is insulated and protected by a rugged rubberized PVC sheath.
13) Wiring Harness
Wiring your Golden Fuel System is easier and more straight forward than ever. With our exclusive GFS wire bundles connecting your gauges and switch in the cab of your vehicle to the wiring terminal is as simple as matching colors to numbers. Simply run the switch bundle and the gauge bundle through the firewall and connect your color coded wires to their appropriate terminals. No splicing, no guessing, a seperate wire for every terminal, color coded and straight forward.
14)Â 3 Position Switch
The 3V assembly is controlled with a marine grade 3 position lighted switch. ON-OFF-Momentary. On for Vegetable oil, Off for diesel, and when you hit the momentary switch it triggers our exclusive GFS adjustable purge Controller that flushes the engine with diesel and returns the vegetable oil to the appropriate tank. Once the purge is complete the light goes out, and you are on diesel.
15) Terminal Junction
Our numbered terminal junction is the central wiring hub for your valves, pump, heater, sender, switch and gauges. As long as you can count and aren’t color blind, you will have no problem wiring your GFS system.

After watching fuel prices reach $2.69 here in the southwest I finally had enough! I ordered up a Greasel conversion kit for our 1985 MBZ 300D Turbo and had it installed in an afternoon. (It took more time to purge the air than most of the installation!) The new 3B hose makes about the most professional installation you can get, and the Racor 660 filter/heater jacket has been working without a problem, even on some of our 35 degree mornings. Everything I needed was in the installation kit... Our 'soy farm' (2- 55 gallon black drums with barrel pumps) is full and I have 20 'jugged' gallons on the shelf to boot. We recently went to the Grand Canyon from here in Phoenix and made the trip up & back never stopping for fuel! Even my wife, who is not a motor-head, drives with a grin now...
Why we are getting lobbied into buying middle-east oil and drilling new wells is a real crime. America could be totally independent using renewable oils grown by our own farmers right on our own soil. Diesels being built today are powerful, smooth and fast and instead of building more gasoline engines we could be putting cleaner next generation green-oil cars on the road. (I have a business park with 14 petroleum oil fired heaters back in Upstate New York and filtered WVO is lighter, and burns without soot...)
By the way, I have chosen to not start on diesel, (I never want to buy another gallon), and switch to WVO when temps are up. We live in a temperate to warm climate and most of the year the ambient oil temps will be in the 90's. This time of year with temps that dip into the high 30's we still start easily on straight WVO. I'm told this can damage injector pump mirror surfaces and carbon cylinders... I'll let you know as time goes on! (Our MBZ has just turned 200K and runs better on WVO than diesel).
