So I bought a 1977 Hilux, and the gauge doesn't work when less the half full.

My question is, where can I find a new sensor? is it part of the pump, or is it by itself?

Thanks in advanced, as I am completely stumped!

 

Sounds as if it maybe stuck. If not stuck it bad. As far as replacement. No clue on that year model.

 

I don't thinks its stuck because it just goes to empty unless more then half

 

I had a rt132? corona lift back with an 18R (Australia) and the contact on the float in the tank has more side to side movement when the tank gets lower due to fuel sloshing, it was simple to fix just remove the screws on the sender in the tank and take it out and bend the copper contact as they work like the speed controls on a slot car hand piece and variable resistance

 

Thats exactly how I pictured them working, like a slot car trigger. And thanks for the fix, it makes sense now why it starts to go up when turning left but then goes back down.. Ill have to check it out tomorrow.

Is the sender on the pump itself? or is it a seperate thing in the tank?

 

As you call it a hilux I assume that it is not a US version and possibly has a 12R engine or 18R, as these engines did not have fuel injection and the fuel pump is still on the engine block. The sender in the tank and is under a round plate with a single wire connected to the centre of it and has six or eight Philips head screws that hold it in place.

 

Im pretty clueless on what model it is, but it's got a 20r and the fuel pump is in the tank according to parts stores.

 

All carbureted Toyotas have the cam driven fuel pump. EFI engines have the pump in the tank. Parts store people are idiots anyway. I always go to their website find what I need go in and say "I need this" thank u lol.

 

I dont have a cam driven pump, I can tell you that for sure. My '80 pickup with the 20R did but this truck (its a '77) doesnt even with a 20R and being carbureted

 

The 20R was a rare item in Australia as after the 18R we had the 2 and 3Y engines in the hilux.
I guess your 20R hilux has an inline electric fuel pump now such as a facet as they are a quick fix and in recent years due to eBay are now cheap. In the Suzuki lj80 f8a engine 4x4 the diaphragm would split in the pump and very quickly fill the engine with fuel and the facet electric fuel pump was the solution, even now in diesels with rotary injector pumps (Mazda) the rear seal leaks air and costs a small fortune to repair and are prone to fail, a facet electric pump saves from needing to continually to reprime the engine each morning

 

Good to know!!
