Send It! (to the bin)
My car now takes about 48 litres of fuel. I noticed though that the gauge was not going down. Given it is not a car that sips petrol I found this hard to believe. Fuel level sensing is done by the fuel tank sender. It has a float on an arm that moves up and down with the fuel level and that in turn moves a variable resistor.
First Hypothesis - Gauge is wrong
I fitted a spiyda Gauge Wizard when I fitted the tank as the sender and the gauge were definitely not a matched pair. Because this needs calibrating, I had it accessible in the footwell so all the wiring (+12v, ground, sender, gauge) were all usefully accessible. I removed the Gauge Wizard and connected a multimeter between the sender and ground. I then drained the tank and pumped in 10 litres whilst watching the MM. The readings did not change as they should have done. The gauge is not a suspect.
Fighting To Get It In
I’ve now made all my brackets, detoured via tidying up the wiring and I’m now on getting it in. This car was designed to take a 6 gallon MG Midget tank. I’m trying to get a 10 gallon tank in. It is not going well.
The tank is catching on the diff cover of the axle. I may be able to get away with taking the rear cover off, or I may have to drop the axle from the car.
Fisher Fury Fueltank Fun
(Update 04/02/24 Combing everything into one post as it wsa getting tedious)
Fitting the new fuel tank to the Fury is the gift that keeps on giving.
The original tank had both mounting holes and a pipe on the top to connect the fuel hose to. The new larger tank has no mounting holes. I made some brackets to the profile of the new tank and drilled mounting holes using the top pipe centre as a reference point.
Charging The Car
Some notes as I go along. We have
- A Renault Zoe
- A Growatt hybrid solar/battery system
- An OpenEVSE charger
- HomeAssistant instance
- An MQTT broker
The challenge is to get all of those talking together so that when the growatt battery is full and the sun is shining, any excess solar goes into the car rather than the grid.
It’s a little confusing as OpenEVSE seems to push OpenEnergyMonitor as the way to do all of this. However I don’t want yet another service on the network when I should be able to do all of this with what I have.
