Quick Chat About Your Car’s Fuel System – From Our Workshop to You

Fuel leaks can make your car unsafe to drive and should be repaired as soon as possible.
Alright, so you’ve just popped in from Rototuna or maybe you got stuck on Peachgrove Road and noticed a funny smell around your car. We’ve seen it heaps here in Hamilton – fuel system issues aren’t rare, and with all our local stop-start traffic, potholes in Nawton, and the odd rough patch around Dinsdale, things can get knocked around under your car faster than you’d think. Let’s clear up what’s going on when your car fails its WOF because of a fuel leak or some fuel system drama.
Even if you just drive your Suzuki Swift on short runs to Glenview, or your Toyota Auris is slogging up and down State Highway 3 to Cambridge, your fuel system’s doing the hard yards. Petrol (or diesel if you’re running a Euro like a VW Passat) starts in the tank, gets pumped through the fuel hoses, and then up to the engine via the injectors. If anything’s off — a dodgy fuel pump, busted hose, rusty tank — you’re asking for trouble. Sometimes it’s a little leak that’s just started, sometimes it’s sprayed all over the rear bumper after hitting a bad pothole on Te Rapa Road.
Why Did My Car Fail Its WOF for Fuel Issues?
There’s a few classic reasons we see cars fail for this, whether it’s a Nissan Juke from Morrinsville or a Peugeot 308 from Hillcrest. Here’s what we come across most:
- Leaky fuel hoses – Any leak in your fuel lines means petrol can drip out. Not only does this waste money (petrol ain’t cheap in NZ!), it’s a big fire risk. Plus, it might leave you stranded on Avalon Drive on a grim winter morning.
- Loose fuel tank – Seen this a few times after someone bottoms out on a speed bump in Flagstaff. If your tank’s wobbling about, you could end up with fuel sloshing out, or worse, a crack that leaks petrol onto hot exhaust parts.
- Missing or broken fuel cap – Might seem like nothing, but without that cap, you risk petrol fumes leaking out and even the odd fuel spill after a sharp left onto Ulster Street. Plus extra air can mess up how your engine runs, especially in stop-start city traffic.
- DIY mods on the fuel system – Big one for some Euro cars (Audi, Citroen). If previous owners have mucked around with pipes or fittings without proper gear, odds are it’ll fail a WOF. No shortcuts here.
There are more reasons too for a failed WOF – if you want the full list, the NZTA puts it all up here: WOF requirements for fuel systems in New Zealand
