Fuel line failure- diesel

[Levi]

Hi all. While sitting here incredibly inconvenienced, waiting for roadside assist… I figured I should let a few of you know.

Thankfully, I just got back from the bush, and I’m in civilisation. I could smell diesel and looked around to find the problem. From the rear left-hand wheel the brake line runs up near the filter and crosses the diesel line. They touch the constant rubbing has resulted in the diesel line wearing through. And I’m now isolated and stuck waiting for pick up.

I would definitely be checking my vehicle if I were all of you as the way the hoses routed on mine, this is an inevitable problem.

Whilst under the car I’ve also been lucky enough to find an oil leak… Heading on a flatbed back to the dealer today hopefully.

Thanks for the heads-up. That's a serious and scary failure.

Definitely check where your brake and fuel lines cross under there. If they are touching, that constant rubbing will wear a hole in the line, just like you experienced. It's a major design flaw.

Hope the dealer fixes both the fuel line and your new oil leak without a hassle. Safe travels after this.

Sorry to hear about your troubles but I’ve noticed there are plenty of potential spots around the Grenadier where hoses can abrade especially coolant and fuel lines. I’ve taken some time and installed protective wraps around spots where hoses cross each other or are up against a sharp piece of metal. I think IA could have done a better job with their routing and securing of hoses.

I think the brand I used was either TechFlex or DuraFlex. They have wraps in various sizes the you can wrap around hoses/lines without having to disconnect them and they are secured with Velcro down their entire length so are nice and secure.

Thanks, how about doing a write up and putting it in the Resources section. with the brand you used plus the sizes you chose.

Thank you. Had a look and whilst mine wasn’t touching. I suspect yours maybe missing a clip which secures brake line but thanks for the heads up because I discovered something maybe worthwhile sharing so people can check. Same area, rear passenger radius bolt ABS wire was rubbing against the bolt. I’ve now re secured with a zip tie and tidied up the fuel line with a zip tie and foam backing so it doesn’t rub

There are enough routing differences between Diesel and Petrol models I don’t know if I could cover everything in a write up (mine is Petrol). But what I would suggest is breaking the inspection into quadrants. Left front, right front, firewall area, either side of transmission tunnel underneath, left and right side of engine compartment, transfer case cable, left and right rear axle, each wheel well, etc….

Most of the issues are with the coolant hoses right at the front and the routings which go out to each radiator in the bumper but as others are noticing, ABS wires, fuel lines and anything that is close to or attached to the axles as they articulate are worth inspecting. Not uncommon for clips or cable ties to go missing with vibrations and vehicle flexing off-road.

Most of the smaller coolant hoses are 25mm I believe so any wrap which covers that size should work. Biggest thing is looking for missing or weak clips and like others are doing replacing with zip-ties or other automotive specific clips.
