Konis and Fuel..

Scored a pair of used Cobra IRS Konis for car #2. Fresh rebuild on these with zero miles. Came with shock dyno sheets too which was a bonus. With car #1 getting closer to an operational state by the day, we are trying to get everything in hand to be able to dive into the next one.

Moving onto the fuel system – we decided to run a 2003/2004 Cobra fuel pump assembly. This is a unique 2003/2004 only setup that comes with dual pumps to provide additional fuel with the supercharged application. Since they cost a fortune new, we opted to go the used route as usual. We decided to run a returnless system like the stock vehicle. This system uses an FPDM (Fuel Pump Driver Module) to duty cycle the fuel pumps to target a desired fuel pressure which is measured by the computer at the fuel rail. Alternatively, we could have run a return system with a pressure regulator, but we opted to use what came with the Mustang originally.

As for fuel tank – for now we will use a stock 68/69 Torino tank. We will weld in a flange on the top front center area to allow this fuel pump module to bolt right in. We will build a reservoir/baffle setup at the base of the tank similar to what is in a newer Mustang to help prevent fuel starvation. Float rod will be a custom one using a stainless welding rod to take the shape of the Torino tank into consideration.
