Yes that includes high horsepower applications too.

Some guide-lines:

Plumb the fuel system in metal tubing as much as possible, keep the hose sections as short as possible.

A flexible connection (i.e. hose) is needed between immovable fuel system components mounted solidly to the chassis and
fuel system components mounted flexibly to the chassis with rubber (i.e. the engine). In other words, every fuel system
requires at least one section of hose between the chassis and the motor.

Plumb the pump suction in ½” (AN-8) tubing or hose in applications up to 550 BHP
Applications over 550 BHP should upgrade to 5/8" (AN-10) tubing or hose between the tank and pump

Install a high flow fuel "pre-filter" designed for the fuel pump inlet, ~ 75 to 150 micron
Pre-filters are usually larger than "post-filters".

Plumb the pump discharge in 3/8” (AN-6) or ½” (AN-8) depending upon the application

Install a high flow fuel "post-filter" designed for the fuel pump outlet, ~ 10 to 40 micron

Don't mount filters perfectly horizontal. They should be mounted so the outlet is elevated above the inlet.
This purges air instead of trapping it in the filter.

Inexpensive 3/8" inlet and outlet cannister style in-line filters include:

Inexpensive 1/2" inlet and outlet cannister style in-line filters include:

Another option in filtration includes the 2" OD aluminum racing filters shown in the picture in my previous post. They are available in long and short versions; there is a variety of cellulose and stainless steel filter elements, and stainless steel screen filters too; and the filter ends are available with AN tubing connections, NPT connections and Push-Lock hose connections.
