i would not recommend it. that will have your fuel pump at a constant run when the ignition is switched on.

What is the purpose of the bypass hose?
I will assume that is in an automobile. A bypass hose goes around the thermostat in your cooling system to allow some coolant to flow whenever the engine is running. This prevents to much pressure to be built up in the system, allows for even cooling at start up and even gives you a slight amount of heat when you start the engine. Your heater core is often part of the bypass system in a car. When the engine's thermometer opens the flow of coolant in the car increases this cooling the engine. As the engine cools the thermostat closes slightly and increases the flow through the core and bypass hose.
You just bought a 86 300zx non turbo and gave it a basic tune up and now it sounds and feels like its sputtering and not wanting to idle you know its not missing it stops at about 2500rpms whats wrong?
It the air bypass unit. be sure there is no leak and the electric connector is attached. To test I have taken it off and temporarily installed a rubber hose. What happens is when you start car the air bypass is open and increases engine idle. Inside the air bypass is a heater that shuts off the air bypass once the engine is up to temp. The air bypass is on right side of engine. It is bolted to engine with two bolts. Air passes out engine through the air bypass and out a big hose connected to air bypass.
What are the best way to guard against vapor lock and overheating?
Supply of fuel (Gasoline or CNG) should be stopped. Try to start the vehical with no fuel supply. It will comsumed the pressure build up due to Vapor Lock & engine will start. Then after engine star , you can open the fuel supply.
Will the engine fire but not start if clutch switch is bad?
In most cases, the engine will not fire or start if the clutch switch is bad. The key will turn in the ignition but there will be no turn-over or sound from the engine. If the engine turns over but doesn't start, there might be a problem with the fuel supply.
How do you bypass a starter to start a car?
You typically can't bypass the starter - that is, after all, what actually turns the engine over to start the vehicle. If you have a manual shift vehicle, it is possible to roll start the vehicle. The key needs to be in the on position. You would roll the vehicle while it's in neutral, jump in, and shift it into gear.
Will a car start if the fuel pump has gone out?
No, of course not. The fuel pump supplies fuel to the engine. The engine will not run without a supply of fuel.
How can you over ride or bypass the factory alarm on a 2000 Chevy blazer It causes the engine to start intermittently?
Factory alarms are, by their very nature and by design, difficult to bypass. It is almost a dealer issue, but some automotive locksmiths can help.
When is the resistor bypass used in the ignition circuit?
The resistor bypass in the ignition circuit is used when starting the engine. It bypasses the resistor to provide full battery voltage to the ignition coil, ensuring a strong spark for a quick and reliable engine start. Once the engine is running, the bypass is no longer needed and the resistor is re-engaged to limit the voltage to the ignition coil for normal operation.
Why isn't the car starting after replacing the fuel pump?
Your new fuel pump is apparently defective. A fuel pump is required to supply fuel to the engine, and the engine cannot run (and of course not start) without a supply of fuel.
What happens if you do not change a bad fuel pump?
Your engine will not start or will stall from lack of a fuel supply from the fuel pump.
