Aftermarket Fuel Gauge ?

Hi guys
Does anyone run an aftermarket fuel gauge in their 88" S2a / S3, that works if so which one please, i've recently tried x 2 gauges the first one was a multi ohms one which at the time i didn't know what ohms mine should be so i just took a chance and it just wouldn't read right probable as it wasn't compatable with my sender ( S3 sender ) then late i found out what the ohms should be ( 240-33 ohms ) and found another gauge that worked with these ohms so after fitting the gauge and with full tank of fuel i took it for an 80'ish mile round trip and the gauge stayed on full, i still have the wire taped up for the old working gauge close to tank so i re-connected it and the gauge read 3/4 full ( 200tdi ) the reson for this is i just want a closer gauge that matches the rest of my 52mm round gauges i have

Silly question, maybe, What's up with the original one?

Have you measured the sender ohms with a multimeter?

Old wiring and voltage regulator can cause problems.
Fit a capillary type gauge and know the actual temp.

Gauge and sender must match. Best way to do this is buy from same supplier. Then wire up and test off the vehicle. It's a smiths sender so you should be able to get a sender to match the bolt hole pattern.

I got a marine one. Works a treat out of the box.

Nothing it works fine but as its a 2a and i now wear spec's i want a gauge that i can read easy without removing my spec's all the time where as with my other aftermarket gauges i can read with ease with or without my spec's on

Ain’t a clue. It’s been in 7 years. I’ll have a search on my account when I return from work in the morning.

There is a way of tuning any gauge by installing adjustable resistors on the positive going in and the negative going out and I was expecting to go down this rout but I just randomly ordered one and it just worked. I’ll have a look and get back to you.
