Let the truck warm up and open the hood. Locate the fuel filter on top of the engine.
It's about 3" from the oil filter and has 3 SS lines going to it.
It also has 2 SHCS or 2 TORX head screws about 1/4 di. heads.
After the truck has warmed up, you should notice leaking fuel collecting at the bottom of the fuel filter. This is caused by worn o-rings. Replace the rings or the whole filter housing.
One. Located near the back of the engine on the drivers side.
Short answer? It won't! Not even for a little while. Long answer... If you screw up and accidentally pour some unleaded into a fuel tank that is partially filled with diesel, it MIGHT run... IF you haven't diluted the diesel fuel too much. Back in the old days, truckers would sometimes mix a little gasoline into their diesel fuel in the winter to help prevent low-temperature gelling. These days, diesel fuel is winterized seasonally, and most diesel trucks and cars come with fuel system heaters to prevent gelling anyway.
New ractors use diesel fuel but back before the 1970s they used gas or distilate (furnace oil).
Is the fuel cap venting this would allow air into the fuel tank so it does not become a vaccum .
No, it doesn't. Some vehicles though may have parts of the fuel system so located that a leak can cause diesel to enter the clutch housing anyhow, basically by the fuel dribbling down the side and back of the engine.
in the tank... ---NOT TRUE! THE 2003-2004 1/2 FUEL PUMP (or lift pump) is located behind the fuel filter on the drivers side of the engine block. The fuel filter housing has a large black top bout the size of a mason Jar with a 29mm nut for removal or filter... Fuel pump is bolted to the back of this... there was a soft recall when these parts failed, and dealer installed a retro-fitted fuel pump in the tank... but only after the OEM original one failed.
That is not necessarily the case nowadays. Diesel fuel was much cheaper because there were far fewer cars with diesel engines. Since many more cars have diesel engines now the various governments increased the tax on diesel fuel to increase the revenue it receives. As did the fuel companies to to a far lesser extent. Diesel fuel is almost always higher than gasoline. Reason being is the EPA regulations a few years back regulated that diesel be made much cleaner that it was in the past. It costs more to refine this clean diesel. Have you noticed that you do not see black smoke bellowing from diesel trucks anymore.
you need to crack loose the injectors and let the fuel pump push some fuel (and air) out around them then tighten them back up.
if it is a diesel it is built in to the fuel filter that is on top of the engine. on the 7.3l there is a yellow lever on the back of the housing that you can drain the water/fuel from it
I think it is back by the left passenger door.
Diesel fuel's price depends entirely on your location and what era you are in. Right now in eastern Washington state, diesel fuel is above $4.00 a gallon, and back in the 2008-2009 global enconomy crisis, I saw it for $5.26 at its peak! But anywhere in the US, you're looking at dumping around $4.00 for every gallon.
