There are several sending units in that vehicle such as the fuel sending unit, the oil pressure sending unit, the temperature sending unit. Need to know which one you want to change.
It is in the back of the engine near the distributor
top rear of the motor, next to the distributor
You will have to remove the gas tank and install a fuel module.
it is located behind the distributor on top of the block there is the oil sending unit and a oil sending switch with a wire that goes to your choke if it is electric trace it back and you will find it...
Which sending unit? Oil pressure sending unit? Engine temp sending unit? Fuel gauge sending unit?
IF I KNEW I WOULD NOT BE ASKING
DID U HAVE ANY ParTICULAR SENDING UNIT IN MIND ???
how do you replace the fuel sending unit
on the engine
There is only a few things that can cause this kind of failure.Faulty gage.Severed or shorted wireStuck float on the sending unit (The pump and Sending Unit are in one piece in the fuel tank itself)Or a fault in the sending unit itself.If the gauge is intermittent, call your closest Chevrolet Dealer and ask about the Chevron fuel treatment. GM carries a part number for it. Teckron (sp?) is the additive that cleans the sending unit and usually makes it work (again)!
The 1994 Chevrolet Astro V-6 engine temperature sending unit can be located on the front of the engine. The temperature sending unit will be next to the thermostat housing.
It has both.
