Having a relatively low compression engine, you can run an 87 octane fuel in there. If ethanol is added in your area, up to 10% is fine. If you do have ethanol, don't bother adding dry gas because the ethanol is dry gas. (any alcohol is hygroscopic). Adding a higher octane fuel is a waste of $ because unless you are getting detonation, it does nothing for you.

Why does it have two fuel pumps 2000 jaguar s type


the s type models has a saddle type of fuel tank which means it has two compartments ie.to go over the rear transmission system ie, propshaft and differential. it has a electrical pulse width controlled pump to supply the engine.which is on rh and a jet pump on lh side of tank which is not electrical and uses a hydraulic type off system to transfer fuel from one side to the other to balance it all out and has two level sensors for fuel level indication which the instrument pack sorts out the differance for fuel level indications, hope that helps you.

What is code U3E22 for Jaguar S-Type 2006 ?


The engine for the Jaguar S-Type is the same engine as the Land Rover RR Sport, and the U3E22 code is misfiring due to low fuel pressure. Low fuel pressure could be caused by a number of things, which you already suspect:
fuel pump, leaking fuel injector, leak in fuel rail, clogged fuel filter or clogged in-tank fuel strainer, possibly even a leaky/kinked fuel line, or fitting/banjo bolt.

#3 CYLINDER IS FULL OF FEUL AND TRUCK WILL NOT START.REMOVED SPARK PLUGS AND GAS POURS ON GROUND WHEN KEY IS TURNED ON FROM #3 CYLINDER PLUG HOLE.


The Vortec engines were notorious for those kind of problems. The problem will be under the upper-intake manifold, and the fuel injector assembly will either have a cracked plastic fuel line running out to one or more of the fuel injectors, or the fuel pressure regulator that is located on the end of the fuel injector assembly is faulty or it has detached from the fuel injector assembly. Either way the lower intake manifold will be flooded with fuel anytime that the fuel pump runs.

There were two types made, the first type had fuel lines that connected to the lower intake manifold, and then from the metal fittings the fuel line turns into plastic and runs inside the lower intake manifold and under the upper-intake manifold where it runs over to the fuel injector assembly, and this type can really flood out an engine when it becomes faulty.

The second type had metal fuel lines running over the upper intake manifold and they connected to the top of the fuel injector assembly, however, under the upper-intake manifold there are still plastic lines to the fuel injectors and also the fuel pressure regulator that could be faulty and cause the engine to severely flood.

The upper-intake manifold is not that difficult to remove, and after you remove the upper-intake manifold then (replace the fuel lines to the fuel injector assembly if it is the second type) turn the ignition to the "Run" position and when the fuel pump runs you should see where the fuel is leaking/spraying from, and it will most likely be a large high pressure leak from a ruptured plastic fuel line.

Let me know if you require any further assistance.

Were is the press nose to cheak the fuel press


Throttle body type don't have one, to check fuel pressure on these type, has to be done at fuel filter, fuel filter gets remove and a adapter goes where the fuel filter fits, that adapter will have the valve to screw your fuel pressure hose gauge, hope this was very helpful.

How do i change the fuel filter in my 1985 cadillac deville (gasoline)


FUEL INJECTED ENGINES The fuel filter on fuel injected vehicles may be located in one of two locations. On all 1976–79 vehicles except the Seville, the filter is mounted in the engine compartment near the fuel pump. On the 1976–79 Seville, and all 1980–85 vehicles, the fuel filter is located on the left side of the chassis just ahead of the rear axle. On 1986–89 vehicles, the filter can be found near the frame, in back of the left front wheel. There are two types of fuel filters used on the gasoline fuel injected vehicles, the one-piece disposable inline filter, used on all 1982–86 250 and 1988–89 273 V8 engines, and the replaceable element type filter used on all the other engines. CAUTION
Fuel is under high pressure: if the steps below are not followed, the fuel could spray out and result in a fire hazard and possible injury.
  1. Disconnect the negative battery terminal.
  2. Release the pressure from the fuel system:
    • Without pressure fitting: Cars without a pressure fitting in the fuel line, cover the fitting to be removed with a shop towel while loosening so that fuel will be absorbed. Dispose of gasoline properly.
    • With pressure fitting: Locate the pressure fitting in the fuel line and remove the protective cap. Loosely install a special valve depressor (G.M. tool no. J-5420) on the fitting. Wrap a towel around the fitting to block any spray and slowly tighten the tool until the pressure has been relieved.
  3. Replace the filter as follows:
    1. On the replaceable element type filter; the fuel filter element is replaced by unscrewing the bottom cover and removing the filter element. Replace the element and gasket with an AC type GF 157 or equivalent. Hand tighten the bottom cover.
    2. On the in-line disposable type filter; the fuel filter canister is replaced by loosening the fitting on the end of the filter, then use a pair of pliers to expand the clamp on the other end and slide it down past the point where the hose extends over the inlet of the filter. Gently twist and remove the hose, unscrew and remove the fitting. Remove and discard the old filter. Install the new filter into the hose and replace the clamp. Reinstall the fitting, and check for leaks with the engine idling. NOTE: A dry fuel system on cars equipped with EFI/DFI may require a substantial cranking period before starting. Be sure to crank the engine in short bursts, allowing time for the starter motor to cool between each burst.

Where is the fuel filter on Chevrolet 1993 S-10 Blazer


Inline Filter Some trucks may have an inline filter. This is a can-shaped device located in the fuel line between the pump and the carburetor. It may be made of either plastic or metal.


Internal Filter

Two types of fuel filters are used, a bronze type and a paper element type. Filter replacement should be attempted only when the engine is cold.
