INTRODUCTION GTR 485 FUEL PUMP BASKET UPGRADE INSTALL GUIDE UPDATED 05-14-17 Welcome to the Install Guide for the Visconti Tuning s GTR 485 FUEL PUMP BASKET UPGRADE. 485 pumps in our preassembled baskets now come with slim connectors that do not require any adapters. Important! When the gas gauge shows 1/2 your passenger side of the gas tank is 100% full, installation is best done when the car has less than half a tank of gas. Please also keep in mind this system was designed with the intention of having the fuel pumps fit very tight. Not using the provided LUBE will 100% tear the orings in the prefilter blocks. You will have problems if you bypass the fuel pump controller with a direct hardware kit that causes the primary pump to run at 14volts during idle. This will overrun the venturi pressure relief valve causing fuel pressure to creep 15-20PSI at idle.

Place the two of provided O-rings in each port of the filter housing. STEP 6A.2.3- Before installing the pre-filter block on the back of the fuel pump you ll need to loosen the filter housing from the billet top. Not doing so will prevent you from lining up the bolt holes for the pre-filter block. Once both pre-filter blocks are secure tighten the filter housing until it is flush with the billet top.

There is no need to remove the fitting, simply make sure it is tight. A fitting that is loose or hand tight can cause extended cranking when trying to start the car. Although you ll be able to place this upgraded stock basket into the gas tank fully assembled you will not be able to connect any of the fuel lines until the is in the gas tank. 7 P age
We have cut open the side of the gas tank to show you how the unit looks when installed. Take notice how we run the fuel feed line. It s important to make sure none of the fuel lines interfere with the level sensor. We recommend looping the fuel feed line away from the fuel level (around the basket) If you have any questions or problems contact us via email, not facebook or some thread on a fourm. john@vtune.us 8 P age
