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.

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.

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.

1 INTRODUCTION GTR 485 FUEL PUMP BASKET UPGRADE INSTALL GUIDE UPDATED 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.

8 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 , not facebook or some thread on a fourm. john@vtune.us 8 P age
