Oil Pressure Switches The Key!
A simple fuel sump design with an in-tank pump. For external in-line pumps the fuel pressure and return lines may also be attached to the sump. For an electric fuel pump to have long life it must have a constant supply of fuel. Fuel is the life of the pump. The fuel acts as a lubricant and as a means of removing heat. Keeping the electric pump far away from the gas tank: Electric fuel pumps don’t pull fuel as well as they push it. So, you want to install it close to the gas tank for optimal performance. So, you want to install it close to the gas tank for optimal performance. Mounting an electric fuel pump. From Crankshaft Coalition Wiki. Jump to: navigation. Pump mounting. Electric pumps were designed to push fuel, not pull it. Install this inline in the power wire from the pump to the ignition switch and you'll have the same protection as the newer Ford cars enjoy.

Their are many types of oil pressure switches, most common ones are normally closed. These WON'T WORK.
These common ones will not work as we need a Normally OPEN switch that closes when oil pressure crosses some threshold. In poking around the web I found the Wells Vehicle Electronics site.
The Wells site has listings for many different style of senders. The main thing we are looking for is 'NORMALLY OPEN' or 'NO', or a combination switch that has both a NO (Normally Open) and a NC (Normally Closed).
For most common applications the 2 Prong PS113/PS114 or 3 Prong PS118/PS122 will work. These are available in either 1/8' NPT or 1/4' NPT so be sure what you order. They are available in long reach as well as a few other threads and style of connectors and fittings. Check out the Wells site for selection.
Both the PS113/PS114 and PS118/PS122 have standard spade connectors that can save some money if you don't want to spend on the waterproof harness plug. The 3 Prong PS118/PS122 can replace the PS113/PS114 as it only has an additional circuit for a warning light. Otherwise they are the same.
My preference would be to get the harness for the PS118/PS122, which is a 3 wire unit but can be used on the 2 terminal types. If needed later if you ever want a warning light, it's ready to go with the third wire
Car and Truck Fuel Pumps
Your vehicle's fuel pump is a critical component that allows fuel to pump from your gas tank to your car's engine. Installing a new fuel pump may improve engine performance; just be sure to know what type of fuel pump is best-suited for your specific vehicle. While replacing your fuel pump, you can also use the time to check or replace other key parts of your fuel system as this will also help enhance your car's performance.
What types of fuel pumps are there?The fuel pump is a crucial component that pumps fuel from your vehicle's gas tank, through your fuel filter, and into your engine. Automotive fuel pumps will typically fall into two distinct categories: mechanical and electrical.
- Mechanical fuel pumps: This type of pump is common on older vehicles that have a carburetor. It feeds fuel directly into the carburetor using gravity.
- Electric fuel pumps: These are standard on newer fuel-injected engines. This type of pump sits inside the vehicle's gas tank and pumps fuel into the fuel injector at a higher rate of pressure.

How do you install an electric fuel pump?
While replacing the fuel pump itself is pretty simple, there are a few steps you will need to follow to safely access the pump.
- Disable power to the fuel pump: You can do this by simply removing the fuse that powers your pump.
- Bleed the fuel line: After removing the fuse, turn the ignition and wait for the engine to stall. This will indicate there is no fuel pressure.
- Lower the fuel tank and remove the fuel pump assembly.
- Replace the pump and re-mount the fuel tank. If you have not done so already, now is a great time to replace your fuel filter to further improve your fuel quality and engine performance.
When replacing your electric fuel pump, it's also a good idea to inspect the other parts of your system. This will help your engine perform at its best and get optimal fuel mileage. The following items should help you:

- Inspect the fuel pump fuse: Since you will likely be disconnecting the pump's fuse anyway, it's a good time to check this as well.
- Check your fuel filter: Checking and replacing your fuel filter based on your vehicle manufacturer recommendations will help ensure your motor runs clean and efficiently. Most manufacturers recommend that you change the fuel filter when you change the fuel pump.
- Use a fuel system cleaner: Using a quality cleaner can help remove any unwanted deposits in your system and can increase your engine's performance and fuel efficiency. Using a cleaner after every oil change can help keep your motor performing well.
