Trophy 1200 2003 fuel tank
« on: March 14, 2021, 09:29:11 pm »
Hi guys!

Checked the valves on the Trophy 1200, 2003 model and did a rookie mistake. I have not exactly marked the fuel lines of the tank.

I could also not find anything in manuals or YouTube what could provide an answer to my question: Does someone has a picture/video/manual of how the hoses should be installed to the fuel tank? I have marked the "main" vacuum and fuel hoses and put them back on, but... There are 2 tubes (one of them is probably vacuum tube) at the "end" of the fuel tank (close to the seat), one of them is leaking fuel if it is held in a certain way.

What hoses should be installed to those pipes?

I don't think I will find any answer to your problem, as this forum is from the Trophy 1200 from the year 2012 onwards ...

I would check the fuel tap doesn't have a damaged diaphragm. This will cause fuel to leak out of one of the pipes. Service kits, including a replacement diaphragm, are available from Sprint Manufacturing.

Hi,

Thank you for your reply.

Have actually replaced the vacuum kit and gasket of the fuel tank.

However I am not completely sure if you understood what pipes I meant. They are not connected to fuel tap in any ways. 2 pipes are located far away from the fuel tap.

Are you talking about the carb vent pipes? They just hang down the back of the gearbox in front of the swing arm.

Warning - If you haven't done it already / don't know about it, do this before you put the tank back on. The two fuel hoses going into the T pieces on the carb common rails have small filters INSIDE the hoses at the carb ends. Take the hoses off at the T piece, you should be able to pick the nylon filters out without too much trouble as they are just push fit but be cautious as they are often brittle.

I'll try to get a photo tomorrow if you can't find one online.
