230 GE Boiling Petrol - Solution?

[Riaan Harman]

We went on a trip to Kaokoveld and on the road through Botswana the petrol of the G boiled causing the petrol to be to thin for the petrol pump to manage.

On closer inspection it seems the exhaust pipe going over the petrol tank is mainly causing this problem.

What do you suggest I do -

1. Re route the exhaust pipe to the same spec as the new G's with the plastic
tanks?

2. Re fit the isolation over the tank.

Thanks

I haven't had any problems with my 230GE like you mentioned, but maybe haven't drove in hot conditions for long periods like you have. A pun inspection I did find something that looks like insulation on my G. See photo attached.

What is the boiling temp of petrol?

That's the one! Mine is a bit warn out.

I don't know what the boiling point is sorry just know in Bots on the road it gets very hot indeed.

HI Riaan

My 230GE was modified by the previous owner in a very clever way. The exhaust system was cut-off approx 30cm before it reaches the fuel tank, and an almost 90 deg bent was inserted to the right (looking at it from the top) where it now exits just below and in front of the right rear wheel arch.

I think this not only resolves the problem as you described but also reduces the risk of fire whilst travelling in the bush. If you think about it field grasses can and will get caught between the exhaust above the fuel tank that could have disastrous effects...

I think this modification was very clever and as far as I am concerned this was a huge oversight in the first place.

PS: This weekend I replaced this section with a new section at the total cost of less than R400 - a small price to pay for huge peace of mind indeed.

A friend had his diesel modified in the same way. I have one comment to make: the noise when driving with an open wondow is unbearable, especially on long trips. I would go the 463 route and let the exhaust exit in front of the left rear wheel.

HI Alan I have to agree it is a bit noisier...mine has a branch fitted and that combined with the petrol motor does give it a bit of a whrrruuummmm that tends to get a bit on the load side.

So the 463 route would help if only the driver window is open, BUT if both left and right windows are open it would not make a difference.

Ain't the wheel going to get to warm from the exhaust gasses?

I haven't noticed any issues on my 463.

One thing to note is that the exhaust can burn passenger's legs when they get out on an incline. This happenend to my Dad and he ended up with a nasty burn on his calf.

The exhaust used to be quite close to the tyre, but I moved it over the weekend. Now it has approx 20cm clearance which is more than fine. Have to agree with Munga however that one needs to be a bit careful not to burn when getting out at the back.

May I ask you guys to post some photo's to give me a better idea on how to approache the sollution?
