Big Thanks to Bryce Danna & Bruce St.

Ok, so I decided to go with a single turbo setup….now my
worry at the time was fuel…..I dont want to ever worry about running out, so I’ve
decided to upgrade the whole fuel system in my Supra.

Note:
This tech tip focuses on the basic install fuel system upgrade instructions.

: You will need a good set of tools, mostly you
will be using 10, 12, & 14mm sockets & flat wrenches, screw drivers (phillips
& flat), hammer, etc, etc

:

Here is everything you need for this bad ass
fuel system

• (6) 720 cc injectors
• HKS Fuel Rail
• Paxton Inline fuel filter for turbo cars
• Paxton Kamakaze 750 Fuel pump
• 4ft of -10 AN highpressure hose
• 15ft of -6 AN highpressure hose
• (2) -6 X -6 X -6 AN T’s
• Paxton Fuel Pressure Regulator w/ gauge
• HKS VPC (prom for 720cc injectors) – look at my page for
  instructions on this
• Lots of patience if your going to do this yourself!!

• If you have the Toyota Supra repair manual,
  that will help alot too!

For any bolts you cant break loose, definetly
get a can of this stuff….

Your also going to have to jack the car up on
all 4’s….or get it on a lift….

Here is an over view of the installation….

Here is how this is going to work,

We are going to drill a hole in the bottom of
the tank & run a -10 to the fuel filter….

From the filter we run a -10 to the fuel
pump….

Now picture the rail with 1 1/2ft of -6 from
one end of the rail to the other….

On this loop we are going to have TWO T’s (-6
X -6 X -6)

On one T is going to be the -6 feed from the
pump,

on the other T is going to be the FPR (fuel
pressure regulator),

From the bottom of the FPR we run a -6 to the
tank for our fuel return….
