If you take it in for an AC re gas they should find if any of the pipes are corroded through ..
Normally the fuel gauge is an easy fix .. just needs a wire linking the fuel tank to a nice clear earth on the cars body ..

How to fix a Mazda Bongo fuel gauge
.
No drilling needed
.
It’s common fo
r the fuel gauge to read either
intermittently or not at all. This
is usually
due to an
earthing
fault.
Try this
simple fix
.
Kneel down beside the driver’s door, look underneath your Bongo.
You’ll see the rectangular bulge of the fuel tank under the floor.
A ‘lipped’ seam runs around the tank.
This seam has holes pre
-
drilled into it
.
Now l
ook towards
the rear of the Bongo
.
Just in front of the drivers side rear wheel there’s a ‘T’ shaped metal plate that runs from the sill to
the chassis.
There are 2 holes pre
-
drilled in it.
Or, just behind the offside pillar, there’s a 10mm nut that holds hoses in pl
ace
.
Select a hole on the tank, and either a hole on the plate, or the 10mm nut.
Measure the distance between them.
Cut a length of electrical wire to this length.
Attach an eyelet connector to each end of wire.
Attach the connectors using self tapping scr
ews or small nut & and bolt.
The job's done.
If this hasn’t fixed the fuel gauge fault, contact us, we can fix it
.
