Why is my mechanical fuel pump not working?
If you see a weak stream or nothing at all, then you could have a failed pump, a blocked fuel line, a clogged fuel filter, or an empty gas tank. Check the fuel pump pressure. Attach a fuel pressure gauge either to the fuel line at the carburetor or to the pump outlet then crank the engine.
How do you test a mechanical fuel pump?
To perform this test, you should connect the test gauge to the metal output line using a spare piece of rubber fuel hose and a clamp. Once the connection is sealed, crank the engine over for 20 seconds. This will provide a full pressure reading, letting you know whether or not the pump is still in working order.

How do you know if your Corvette fuel pump is out?
The only way that you are going to know that your Corvette’s fuel pump is going out is that it is no longer providing enough fuel pressure to keep the engine running under a heavy load, or at high-speed. Typically, if you are heading up a hill (or accelerating) the engine may start to feel like it is just running out of steam.
Why is the fuel pump in the fuel tank?
It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do.
What causes a Corvette to not start?
If your Corvette is difficult to start, a bad fuel pump would probably not be the place to start looking, especially if you are’t getting a fuel related trouble code. Instead, we’d recommend taking a look at the ignition system first. Often it’ll be bad spark plugs, or a bad coil pack.
What happens if your fuel pump goes bad?
If your Chevy Corvette’s fuel pump goes bad, no fuel (or not enough fuel depending on whether or not it’s out all the way) can enter the engine. Without gas your Corvette will not run at all. With that in mind, most of the symptoms of a bad fuel pump revolve around the vehicle stalling out or not running at all.
How to tell if a fuel pump is bad?
One of the most common signs that a fuel pump is going bad is a whining sound. The whining sound can indicate that the fuel pump is going out before there are any performance based issues. Keeping an open ear can save you from getting stuck somewhere with a bad fuel pump. It’ll sound like a low frequency buzzing sound.
How to tell if fuel filter is clogged?
How do you tell them apart? A clogged fuel filter will have high pressure on its input side and low pressure on its output side. A bad fuel pump will have low pressure on both sides.
What does a Corvette need to start?
At the most basic of levels your Chevy Corvette needs three things to start: Air, fuel, and spark . If any of these things aren’t present, the engine won’t turn over at all. If there’s been zero warning that the fuel pump could be going bad (hesitation, difficulty starting, etc) then it should not be automatically assumed ...
What to do before disassembling a fuel pump?
Before disassembling the fuel pump, either mark or make a note of the positioning of the upper and lower fuel pump housings. There are multiple positions available that the lower housing can be placed in; only one will allow proper fuel line and suction hose connections.
Why is my Corvette running out of gas?
If your early Corvette has no power and feels like it is running out of gas, chances are the fuel pump is the culprit. Fuel pumps are simple devices with two check valves, one to allow fuel in one to allow fuel out and a diaphragm to move the fuel. Check valves are one way devices allowing flow in one direction not the other.
How to check if fuel pump is working?
You can test your fuel pumps operation with a vacuum gauge, installing it on the suction side of the pump to see if it is obtaining vacuum. Depending on how long you crank the engine, you can see as high as 10-15 inches on a new pump with tight check valves. If the suction side check valve is good, it should also hold vacuum for3- 5 seconds after cranking the engine. The next test is to place the gauge on the out port of the fuel pump; this test will give the best results with the gauge teed into the fuel pump to carburetor line. If the engine runs, that is even better. Start the engine and watch the gauge. You should see three to four pounds of pressure at idle. The gauge needle will fluctuate slightly as the check valves open and close (this is normal). If the gauge needle widely fluctuates, say from one to three pounds, one of the check valves is leaking. Pump performance will be poor, especially when you need fuel the most under hard acceleration. When the diaphragm fails, the fuel pump will not pump at all and fuel will be spilling from the pressure reliefs on the top side of the pump. Either way, the pump will require a rebuild.

What is a rubber seal on a fuel pump?
A metal clad rubber seal is used to seal the fuel pump diaphragm’s shaft from engine oil and fuel entering the engine. These seals often come loose or leak. I use naphtha to clean the seal area before the sealer is supplied. The same naphtha cleaner is used to wipe off the seals metal surfaces before installation.
