Mounting an electric fuel pump '''directly''' to the vehicle's frame or underbody, etc. is not a good method for most vehicles. If you solid-mount the pump (bolt it directly to a frame member or other suitable structure of the car), it will transmit the noise and vibrations made by the pump into the sheet metal of the car and can make a pretty good racket that gets old to your ears after a while. | Mounting an electric fuel pump '''directly''' to the vehicle's frame or underbody, etc. is not a good method for most vehicles.

These are black rubber hangers that are about 3/8" thick and 1" wide and look like they may have been cut from an old truck tire. They have holes drilled in them along the length and a quarter-round metal piece riveted onto one end of the hanger that matches the exhaust pipe curvature. The metal piece can be removed and as many of these hangars can be combined to give the size needed, then bolt the pump to the hangers to isolate the noise. One such hanger is the < $5.00/each Walker p/n 36273, shown below: |

A good pump like the Carter P4070 shown below will come with a mounting bracket suitable for most applications, Plus it usually comes with the mounting and electrical hardware. The cad plated bracket has a 90º bend in it that can be bent to fit most applications. | A good pump like the Carter P4070 shown below will come with a mounting bracket suitable for most applications, Plus it usually comes with the mounting and electrical hardware.

| + | The Carter pump is a rotary pump, so is the Holley. A rotary pump will be much quieter and has less vibration. This will result in less noise to the occupants inside the car. It will pump out an honest 4-7 psi. | ||

If you decide to use a Holley Blue or Red pump, they come with a round clamp that grips the cylindrical body of the pump. Below are a couple of pictures of a mounting system that you could use on your application. It's somewhat flexible and protects the pump body from mechanical hazards. | If you decide to use a Holley Blue or Red pump, they come with a round clamp that grips the cylindrical body of the pump.
