R33 Fuel Tanks..

[Denver]

Ok bit of a different question for everyone out there well versed in the r33 fuel system..

The fuel tank, the fuel pump sits on the RHS/driver side of the tank with the fuel level sender, theres a secondary loom that runs off the fuel level sender that goes to the left side of the tank and down to the bottom left corner, what its attached to, i can't see or figure out..

is it attached to another level sender, or is there a secondary pump buried down there to transfer fuel over from the left side of the tank to the right, or does the fuel transfer work of a vacum setup using the return line from the motor, looking at the return line setup at the top of the tank this seems likely, i just want to make sure there isn't a fuel pump down there that may need power.

anyone who's hacked apart a tank or has a manual with this info, id love to hear from you..

There is no secondary pump in the tank that's for sure, just the one in the bracket.

I can't for the life of me think of what it could be though!

pretty sure having looked thorough at the tank cap its a vacum pickup to grab fuel out of the LHS side of the tank, so im pegging it must be part of the fuel level sender, i just can't get a hand intp the tank deep enough to trace the wires down to see what they're attached to..

just trying to make sure its only a 5v power signal it needs to the sender or if it might possible need 12v, anyone got a factory 33 manual handy?

could it be the sensor for the low fuel dash light? I have noticed that my low fuel light is completely inconsistent with the fuel gauge so it would make sense that the sensors for each were in completely different spots.

I think that might be what it is, sounds like a good theory

You can clearly see the particular piece of electronic you are referring to in the diagrams..... But it does not tell you anything about it LOL sorry dude.

P.S. have more faith in google....
