Have you got an old fashioned test light, not the LED type

No just a multi meter the petrol side is obviously working but couldn't get a reading on the fuel reading side

I did get a reading on the pump as its new

I've got a feeling it's somewhere at the front

With the old pump

Float up you can sellotape up

Pins 5 and 6 the small ones

What was the ohms reading on you meter

Is it close to 33 ohms

I posted somewhere this morning it was close to 40 then moved float down it we t to 20 then at the bottom zero

Mmm possibly a decimal point missed or bad contact

This is measured disconnected and at the pump connector

Should be roughly

Fully up should be 30 ohms
Full down should be 300

Yes that is really close to what I have

 

[koalar]

Great

35 is correct

Tape the float in this up position

Pug it into the harness

Switch the ignition on

Don't worry the motor will spin for about 3 seconds only and switch off

Wait, the needle will slowly rise, give it a good 30 seconds to settle, what the highest it reaches

 

[Blueboy54123]

Thank you I will reply tomorrow with results (if any)

Yes the 2 small ones

Use the old pump as long as it's close to 33 ohms fully up

It strange both pumps are working but the gauge never goes any higher than around 3/8

Connect the car's wiring to the old pump. Keep the floater up and turn the ignition on (not crank). Where does the needle go? And when you let the floater easily down, needle does what?

Koala mate we did as instructed plugged the old pump in put the float to the top switched on ignition position 1 the fuel gauge went up to full then we let the float down to zero nothing happened it stayed at full we turned the ignition off moved the float to halfway switched ignition on gauge went to half moved the float up it stayed at half so wherever you put the float it goes there but can't be altered so the gauge is functioning
