Fuel tank unit??? carbed engine
Hi,
Somebody have any ideas what "fuel tank unit" stands for on '87 Camaro LT with originally carbed LG4 engine and mechanical fuel pump.
I have switched to holley TBI, inline fuel pump and MegasquirtII ecu. Have maked up custom wiring. and now want to remove all unneeded wires.

Tank U
Fuel Tank Unit can refer to the fuel gage sender or other device in the tank. It helps to know the context of the discussion.

If People Drove Any Slower Theyd Be Going Backwards
When you see fog lights on in good weather beware. Low performance driver ahead.

Re: Fuel tank unit??? carbed engine
Exactly, the '87 LG4 comes with a little helper in-tank electric. It won't put out much pressure as it was designed to assist the mechanical pump and prevent vapor lock. You'll probably be fine keeping it operational (I'd recommend it). If you disconnect it though, it will become a restriction if left in place.

Re: Fuel tank unit??? carbed engine
The "unit" is the direct output of the FP relay. Its safe to assume it is indeed an electric pump

Don't neglect to include alternate controls for the existing in-tank pump. It is controlled by the existing ECM harness as the wiring diagram shows.
