Hi, just discovered the short section of fuel hose that runs from the bottom of the fuel tank to the pipe under the car has split and having trouble with the replacement. The supplied 1/4" hose is too small to fit over the pipe coming from the tank but is very tight fitting through the hole in the boot floor . As any larger pipe won`t fit through the floor, wondered if anyone had any tips. Have tried putting the pipe in hot water to soften it and using washing up liquid to help lubricate it but to no avail. Thinking of enlarging the hole in the floor?

Yes, that's the way. And, buy a rubber grommet to put in the hole you made, so that the rubber pipe won't be damaged bij the rough iron of the hole.

I do this with the tank lifted a bit. Thread the pipe through the floor, get the end on the tank outlet then pull the excess through the floor. Sit the tank back down, then from underneath put the jubilee clip on the hose/tank outlet.
The fuel hose should be 1/4" ...... a larger size will leak!

Thanks for those 2 very different solutions! Any tips on getting the 1/4" pipe on, the inside wall became damaged during my attempts to get it on, seems much too small?

Is this 'plain' fuel hose - or something bifferent? It might be an idea to check it really is 1/4" / 6mm bore.

Hi, Thanks. Not sure have attached pictures to demonstrate problem (which also shows type of hose). Cheers Mike Attachments:

That doesn't look like 1/4!

I agree that it looks tiny, does say 1/4" on it though, have ordered another length from different supplier will let you know how it goes. Strange thing is it is very tight through the hole in the boot floor despite its tiny internal diameter?

Yes - it seems almost to be cooling hose. Fuel pipe isn't normally that heavy! Even the Smiths type (braided) hose is easy to get through the floor

Finally resolved this problem and thought it might be useful to someone else to mention how. I Bought several other types of fuel hose to see if it was down to the type I had originally purchased, but all of these alternative 1/4" hoses were the same and far too small to fit onto the bottom of the fuel tank! (see picture above). After much head scratching I bought an 8mm (internal diameter) fuel hose that fits easily onto the fuel tank, however this will not fit through the hole in the boot floor. By chance I discovered that the hole that takes the breather hose from the top of the tank (via a grommet) is just large enough for the 8mm fuel hose. Problem solved I thought! Er no. The 8mm hose is too large for the main fuel pipe that runs under the car! I then bought an 8mm metal joiner that was both tapered and stepped which made it possible to join both the new 8mm hose running from the tank and a section of new 1/4" hose which I then connected (under the car) to the main fuel pipe. (I found it easier to sort all this out first and then cut the 8mm hose to length and fit it to the tank when everything was in place). For the breather I then ran a new piece of 1/4" fuel hose from the top of the tank through the remaining hole in the boot floor as it seemed a better solution than using the original thin plastic pipe without the grommet as it would not fit in this hole due to the smaller size. All seems to be working well so far (no leaks!!) Please take care if you are doing this as despite draining the fuel tank there was still an alarming amount of fuel in it when I removed it from the car. Advise wearing gloves and eye protection when working under the car to protect you when disconnecting the hose from the pipe. Also only put a small amount of fuel back in to start with so that you can check everything is leak free before you drive off! Hope this is useful to someone.

Hi
This may be a stupid question, but is that the original tank? I do not know if they were different between different models/years, but that hose does not look like it would ever fit over the pipe coming out of the tank...

Hi Hannes, good question! I don`t really know, I am guessing probably not as I haven`t ever had this problem with any of my other minis?

Hi update on my fuel pipe issue. In the end I discovered that I was sold the wrong type of fuel pipe (from a well known mini parts supplier too!!) It appears I had the injection fuel hose and not the low pressure hose that I needed. However this looks pretty feeble so have gone for some proper stainless steel braided hose from Hose Technik who were very helpful. This is also too large for the original hole so have routed it as mentioned previously. Should (hopefully) be strong enough to cope with the unformed edges of the hole. Will keep you posted!!
