Engine Preparation - Factory Five Racing Mk4 Roadster Assembly Manual

These instructions are designed to supplement the assembly manual where the assembly process
is different from the build up using a small block. Sections of the manual that deal with wiring
and motor preparation of the small block will not apply and can be skipped. Read through these
instructions before beginning assembly as some of the changes occur early on in the build up.
If you plan on using an external fuel pump, (the original pump runs to high pressure) the in tank
pump will need to be replaced with either the suggested pickup or one from an earlier (1985)
carbureted Mustang. The old Pickup is held into the tank with a metal ring that needs to be spun
about ¼ turn to be removed. This is best accomplished with a punch (or screwdriver) and a
hammer tapping a little at a time on opposite sides. The pickup can then be lifted out paying
close attention to the alignment of the tubes so the new one can be mounted in the same location.
Larger fuel line is usually necessary for all carbureted kits, the line routing is similar to what the
manual describes for the back half of the car, however depending on the type of fuel pump you
use (electric or mechanical) you may want to run the line differently.

The electric fuel pump should be mounted to a frame rail as close to the tank as is practical. The 2"x 3"
is a good solid location. Some pumps however must be mounted below the pickup so a bracket may
have to be made.

Engine Preparation

The intake manifold used must have sufficient clearance for the air cleaner underneath the hood scoop.
The Edelbrock Torker II manifold will fit but it is about the maximum height useable. The high-rise
intake that comes with the 460 crate engines from Ford will not fit under the stock hoodscoop.
