Seen a lot of diverse discussions about use pipe/braided hose inside but mines a different kind of question lol I have no problem using either BUT


Long story, short...... I have a bucket load of kunifer pipe and a lot of length of braided hose.

My question is...

I have mounted some nice an6 pieces to go from the bulkhead to the engine from the LHD blanking plate. My question is:
Do I use the kunifer on the floor from the inside of the bulkhead to reach the rear?
Or do I use the braided hose from the bulkhead to reach the rear?
The issue I see with both is getting it safely through to the petrol tank with keeping it possible for someone to sit on the rear seat.

Thanks guys.

Just run kunifer front to rear along the underside of the floor pan, then rubber from the ends of that pipe to the tank and engine.... That's how I've done all of my A series minis

You could also sit the pipe in the flutes of the floor, using P clips riveted through the floor to the side of the flute... then fit a piece of removable (dot and dab bonding adhesived?) metal, pvc or similar over the top.

Hope this is some help, using my little amount of common sense ? and what I've viewed on the project threads on here.

I have mine ran inside with hard-line and wish I never bothered. Unless the cars super low (unlikely if you are putting passengers in the rear) I don't see the benefit?

I agree with you on this, my A series powered minis hardly ever scrape a speed bump but if they do it's usually the exhaust link pipe that hangs down slightly so it doesn't rattle on the floor ?

im not asking whether you think its needed or not :D the benefit is, its going to look a lot nicer under the bonnet which is why i am doing it and the chances of any leaks is lot less as well.

the return line can be exactly the same size, why do you which you didnt bother? just because the time it took do you mean? also how did you run it? cheers

Mainly because I was told the return should always be larger than the feed, so I ended up with a 10mm return line which I used two rolls worth because of kinking the tight bend at the bulkhead, and I used flexis in the bay and under the boot floor so there was no possibility of a fuel leak in thecabin.
It's tidy but does not really offer any benefit other than the floor plans clean,At the expense of running lines inside...

Just like hydraulics, drain to tank is always large to reduce velocity and pressure.

Is it legal to have petrol pipes on the inside of a road car? I would have thought not - maybe in a race car.
