Member Bill Heath has used nitrous successfully in his drag race truck, but no one has any hard performance improvement numbers for street use yet. I guess now that I have a part number I could get one. When our name is on the final product, we simply can't afford to ignore such a huge problem! The Racor instructions say to install filter elements only hand tight, but it would appear Racor has an assembly line machine that has very strong artificial hands. I had leaks my teflon skilz are weak. This will sometimes be enough to get the truck running until you drive to a garage. So, with a light fuel load, all my tools, spare oil and coolant, turnpike change, jack and other heavy stuff off-loaded, a double-dose of cetane improver Stanadyne Blue and Four Plus , and injection timing optimized, I went out to smoke the track.
The fuel is under low pressure and they were not orignally, so again- I'll keep an eye out. When I re-mount my filter I'm going to use a larger hose and 2 reducing couplers. Remove the access plug in the top of the bowl by. This is before the mech pump. Now that everything is hooked up, you're just about done.
Since I needed to drive my truck, I opened the air bleed on the Stanadyne filter mount in the engine compartment, hot-wired my new electric fuel pump, and sucked fuel into the new Racor filter, through the fuel lines, and out the air bleed. If your tank is full of summer diesel and it is now winter and cold, your fuel may be clouding up and clogging the filters and injector nozzles. If the mechanical pump fails by developing an external leak, the electric pump could cut my fuel mileage considerably, while washing the underside of my truck with a kerosene-equivalent solvent. The center terminal of the switch is connected to a wire that runs to the brown positive lead on the electric pump. Time to get the engine going again. Atleast the push rod for it so it no lonnger tries to pump.
With hundreds of thousands still on the open road, the demand for replacement parts and maintenance items is still there. My Napa said they don't have listings for filter bases. It is also a water separator and has a drain connection for disposal of collected moisture. The electric lift pump was purchased from Autozone, part no. The result: 0 to 60 in just 11. When priming a new fuel filter, I just flip the switch to the right and pump fuel into the clean filter.
Spin the primary fuel filter onto the threads of the fuel filter housing in a clockwise direction until the filter is tight. I have observed that many boaters automatically add chemicals to their diesel fuel to deal with the possibility of degradation during storage, microbial growth, water contamination and so forth. Basically like after sitting over night when you crank it for the first time you have to re prime the fuel system for it to run. Tighten the valve, the water will not discharge. The new injection system components are doing just great, and I am spoiled by routine starts in about ½ turn of the crankshaft. They are designed to push not pull, it will burn it up. Pump out your fuel tank and fill with clean diesel.
Check the connections for leaks and loose fitting as well as any obvious fuel leaks. This article will advise you on which filtration efficiency you should choose for your engine. Overnight, a little tougher, maybe 10 seconds. Place a bucket beneath the filter housing, and turn the drain valve to the open position to drain the diesel fuel. I have also been gathering parts for this swap. But I could not get the Racor filter element off by hand to prefill it, and I could not drive to the parts store to buy the correct filter wrench.
Further, the company says a 30-micron filter should be used as a primary to filter raw or poor-quality fuel before it is further filtered by finer media, such as a 10- or 2-micron. Keep me posted, i'd be happy to help any way that i can. Save hundreds versus replacing with new! The engine-mounted secondary filter supplied by Yanmar for its mechanically governed engines is 10 microns. Remember, you also need room above the filter unit so you can change the filters, and below so you can drain off water and sediment from the bowls. After opening the fuel system the only way i can think of getting the air out is cracking open the out side of the secondary filter line kinda like bleeding breaks. The engine-mounted secondary fuel filter has a filtration efficiency appropriate for the engine, which ranges from 15 microns down to 2 microns. The filter will have some air in it, the electric fuel pump will have some air in it, and all those fuel lines you drained into the pan on the floor now have air instead of fuel.
Torque cap to 19 lb-ft 25 N-m. Caterpillar mandates that the secondary 2-micron filter be changed after 200 service hours or 1,500 gallons of fuel. About the Author By vocation, Dr. During the transportation and distribution process — not to mention on your boat — there are many opportunities for the fuel to become contaminated with water and particulates that can plug filters. Fuel Filter Base This fuel filter base is suitable for use with pre-pump suction side and post-pump pressure side fuel filters in diesel applications. For these units, Racor offers a choice of three filtration efficiencies: 2, 10 and 30 microns.
You can follow the friendly DieselPage instructions to recover from an airlocked injection pump, but why bother? Turn the wrench counterclockwise until the collar is loose. This is a complete brand new replacement for your stock filter. Tighten the valve, the water will not discharge. This might sound silly, but i think you warned me about blowing a O ring in the fuel pump, if i did do this would it be obvious fuel in the oil? Fuel filter replacement is a critical service procedure, particularly for modern engines such as the 6. Yanmar recommends a 30-micron primary filter regardless of fuel quality for use with the 2-micron secondary filter on its new electronic engines. You should hear the fuel pump in the tank come on. However, that article did not document any performance improvements.
