This was for two senders. Al Scott They rebuilt my senders the same day they received them and had them back to me faster than I would have been able to drive back and get ’em. Price was a lot less than new senders, and mine seem to be working great. John Fuel Senders – How to test – Rebuild them if you can The tank sender is loosly connected via the lock ring to the ground but the circuit does not rely on that connection. There is a seperate wire connected to the sender base black that is to be used as a ground.. To check the system, I cut the 2 tan wires and look at the gas gauge, it should be pegged full. Now ground the 2 tan wires to the frame and the gauge should drop to empty– if this happens the gauge and it’s forward wiring is good. If your gauge shows full now that means there is an issue with completing the circuit which means a wire or the sender is open.

Diagnose Fuel Gauge Copyright AA1Car Nothing is more aggravating than a fuel gauge that doesn’t give an accurate reading, especially when the gauge shows there’s still fuel in the tank when there really is not. Faulty readings can be caused by a bad sending unit, a problem with the gauge, or shorts, opens or weak connections in the wiring that links the two together. But which one is it? In , the first float arm gas gauge appeared.
A float mounted on a hinged arm moved a mechanical pointer on gauge on the outside of the fuel tank to indicate the fuel level. The idea was taken one step further when vehicles started to get better electrical systems by connecting the hinged float arm to a rheostat.
This is what I’m currently using. The intercooler plumbing is nothing more then 2′ 1/4 exhaust pipe. “A” is the 5’th injector (a cold start injector from a Saab), “B” is an adjustable 6’th injector using a NOS fuel solenoid and a fan spray nozzle.
A look at Volvo in-tank fuel pump and fuel gauge sender issues. These notes generally apply to through normally aspirated and turbo wagons and sedans, taken from my family fleet experiences with the following: I have only book knowledge of those years, so this page may not be helpful. Volvo k-jet manual tank pump pages Speaking of book knowledge… It never hurts to carefully read what the manufacturers said about their product.
Volvo factory manuals green books describe the transfer or tank pump in Group The Haynes series on often treats us to photos of real sometimes dirty and rusty cars and evidence someone actually performed the steps indicated, in contrast with the factory literature which is often prepared before the first models even hit the showrooms.
My late edition Haynes describes the pump replacement in Chapter 4 part A. This is no shortcut past purchasing a repair manual. Working in the fuel system is not the next skill level step after do-it-yourself oil changes and brake pads.

Posts 2, Yes, I know there are two. Currently on the low end they read correctly, but it wont go to the high end. Oddly enough, originally the levels were reading high and we ran out of gas with a quarter tank showing in the cluster. I changed out both sensors and then with the tank empty the cluster still ready high.
How to Check Your Fuel Pump. In this Article: Article Summary Performing an Electrical Test Performing a Fuel Pressure Test Community Q&A If you’re struggling to accelerate, especially on the highway, or you notice other signs your car might not be getting enough gas, the problem can be caused by a partially blocked or clogged fuel line, fuel filter, pump, or injector.
The Need for Fuel Polishing The most common reason for marine diesel engines in general, and recreational trawler diesel engines in particular, to fail to run is associated with “bad diesel fuel. The problems come about because of the condition of the fuel we buy and what happens to the fuel when it gets stored, sometimes at the suppliers’ facilities, but most often in our own vessels. Pleasure boats sit idle for long periods of time allowing algae time to grow in the tank.
Most of this contamination adheres to the wall of the tanks and you might not notice a problem while running the engines at the dock. Once the boat is underway and the fuel begins moving around the contamination tends to start breaking away from the wall of the tank and entering the fuel. This contamination can clog your filters and shut down your engines. Having your engines shut down from clogged fuel filters can really ruin an otherwise enjoyable outing, but it could really get bad if you have them shut down while trying to navigate in high seas or critical situations.
Fuel Polishing can help eliminate your Fuel Problems Gulf Coast Filters offer a Fuel Polishing Kit that once installed will be able to polish your fuel while the boat is not in use. You can also hook this system up to polish the fuel while the engine is running. This system uses its own independent fuel pump and continuously pulls fuel from the tank, through the filter, and back to the tank. The GCF Fuel Filter will remove particles below 1 micron and by using this system for hours at a time can polish your fuel to a much cleaner level than standard factory filtration.

Fuel tank, Facet pump, and fuel lines installed on a Challenger. Click on images to enlarge. Sealing Threaded Connections as appear on the Facet pump The first question that will arise when you go to install the hose barbs on the Facet is, “What type of thread sealer do I use? If you have hose barbs that are also brass, no sealer is required. The threads, being pipe threads, are tapered and the design of the thread is such that they create an interference fit as you torque them down.
But, you must torque them down tight, really tight.

Want to add a new high-current accessory without overtaxing the existing electrical system? Perhaps you need to activate an electric fan or nitrous system by means of an automatic switch. A far better solution is to use a relay. A relay is a type of heavy-duty remote-control switch able to handle high-current accessories, yet capable of being actuated by substantially less current.
When the relay is energized turned on , the high current required to operate the accessory flows from the power source, through the relay, and directly to the part. Supplying high-current devices requires heavy-gauge wire; the longer the circuit the larger the required conductor diameter. In volt automotive electrical circuits, even small amounts of resistance can cause significant amounts of voltage drop. Circuits with long wire length and multiple switches and connections inevitably have a certain amount of voltage drop caused by normal resistance buildup; deterioration from vibration, high temperatures, and corrosion only compound the problem.
Relays provide a solution by shortening the required length of the heavy-gauge power delivery wire from the battery or alternator to the load. Relays are typically energized through an operator-controlled dash-mounted switch, or by remotely mounted pressure-, vacuum-, or linkage-actuated switches.

Chad deahn February 11, at 5: Although Over the past two days I have experience problems with just driving down the road and the command center runs out of fuel. When I get out and open the hood and try to restart the vehicle there is no high side pressure whatsoever.
The fuel gauge is one of the most important gauges in the instrument panel. It is simple in both function and operation. When it is not operating properly, it seems to be a big mystery – but it’s not.
Extra injectors just spraying in fuel, how absurd! Was my thought, what about cylinder to cylinder variations and rpm? But Gus Mahon “a. Callaway does it, as does Ak Miller and several other well known turbo kit manufactures. This is what I’m currently using. The beauty of this system is that injector B is tunable to any fuel flow you like by replacing sized “jets” at the nozzle. I got fancy and used mil-spec AN fittings for fuel; its not required A popular question I get is how do I get the AN fitting attached to the cold start valve?
A dab of sealer on the threads and I’m ready to go. All you need is to attach your cold start injector to the pipe with an o-ring and some self tapping screws, tee into your fuel system no leaks now and hook the fuel injector to a pressure switch and a power source. Adding a light on the dash to tell you if your pressure switch is working or not would be a real good idea too!
I get my pressure switches at NAPA and they work great! They even sell ones pre-set to 15 PSI and they are adjustable to any pressure you want.

A good basic tool that gets the job done. The idle air flow is balanced first. The Uni-Syn is adjusted so that the ball rises about half way up the tube. By adjusting the idle speed screws the idle speed is maintained about RPM and the flow is adjusted so that the ball raises the same on both carbs. Once the idle air flow is balanced the service screw is used to raise the engine speed to RPM. The Uni-Syn is adjusted so that the ball rises about half way up the tube at this higher speed.

A malfunctioning oxygen sensor will result in air—fuel ratios that respond more slowly to changing engine conditions. A damaged or defective sensor may lead to increased fuel consumption and increased pollutant emissions as well as decreased power and throttle response. Most engine management systems will detect a defective oxygen sensor. Keeping the air—fuel mixture near the stoichiometric ratio of An air—fuel mixture leaner than the stoichiometric ratio will result in near-optimal fuel mileage, costing less per distance traveled and producing the least amount of CO2 emissions.
However, from the factory, cars are designed to operate at the stoichiometric ratio rather than as lean as possible while remaining drivable to maximize the efficiency and life of the catalytic converter. Carefully mapping out air—fuel ratios throughout the range of rpm and manifold pressure will maximize power output in addition to reducing the risk of detonation.
Lean mixtures improve the fuel economy but also cause sharp rises in the amount of nitrogen oxides NOX.
