Petrol smell in boot

[2319tony2671]

I am a new owner of a 1989 XJ-S convertible wioth only 100,000km's on the oddometer. Never winter driven in Canada. Petrol smell is very "heavy" when opening the boot lid. Are there any other options to look for other than the leaking petrol tank?
I have not yet had a good look at things, some prior knowledge will help a lot

Hi and welcome

i presume you know about the ' rivet ' under the tank that can wear a hole causing the leak, is that the one you referred to,

other than that, all of the plumbing for the petrol is in the boot, it leaves the tank and goes into a swirl pot ( on most models ) under the battery ,then goes to the pump and then through the filter, these all have rubber pipes connecting them, andy of the joints or the actual pipes could be weeping petrol , possibly the filer , as its this one that gets changed , then they go to steel pipes under the car by way of brass unions on the underside of the boot ,

so its carpet , lower battery/pump cover and spare wheel out, and have a good poke around ( with the battery disconnected and removed ) for any leaks you might see, but dont bend the pipes too far......

hope this helps

We are now a few years and much Canadian $ expended. Replaced and revised the breather system, eliminating the pressyre in the tank. No Go. Tank out, found to be leaking,repaired. seemed to be the answer for a while. Smell back mechanic removed tank to inspect that repaior was still ok. It was. He favours now changing the section of the filler pipe which contains a spring loaded flap which seals the filler pipe untill pushed aside by the fill pipe. Another expensive item. Has any one any experience of this item? Should I just go ahead and try to find replacement"plumbing" items for everything involved

Hi,
For what it's worth, I've just replaced all the rubber fuel pipes in the boot of my '74 XJ12 Series2 because they had all set like concrete. There always has been a slight 'wiff' of petrol in the boot

Did chsnging all of the rubber pipes solve the problem? If so where did you get them from,single source? At what cost? No comments re flap valve in filler pipe.

By the way the tank problem was the result of a number of over cooked spot welds, almost through the metal, rust did the rest.
If any one has a single source for all of the "in boot" gas plumbing I would appreciate the info.

2319tony2671,

Many of the tank and underfloor fuel fixtures are still available including the rubber filler gaiter.

Good luck with sorting the problem.

Collectively reponses have stated that all parts are available. Where ? Can I go to a single source in the UK with a parts list for one stop shopping? If so Where?
For both of you did this work CURE your problem?
Were any of the metal pipes replaced?

I need and appreciate your input. thanks

2319tony2671,

My first stop for anything for my XJS is always just to go to Jaguar. The online parts list, diagrams and ordering capability (you can also order through your local Jaguar dealer) plus the fact that I'd rather fit the correct parts than pattern parts makes it an easy decision. My UK Dealer will always give me 20% discount as a JEC member as well.

For the online parts diagrams and prices, just go to www.jaguarclassicparts.com

Good luck

Hi Tony,
I agree with Paul, go to your Jaguar dealer in the first instant to see availability.

Early saloon XJ's had 12 gallon fuel tanks, one in each rear wing. Aledgedly, As result of a major rear end shunt in the USA which resulted in a fire, modification were made. Fuel tank capacity
was reduced to ten gallon each and a flow back valve was introdued into the filler neck just under the Filler cap. I suppose the idea is that should the tank be impacked and the tank cap opens the valve would stop fuel gushing out like a fountain.

With regard to fuel hoses
The supplied hose is compatable with Ethonal lased fuel I am told
I needed 3/8 and 5/16 inch internal diameter hose
Hose under the bonnet is stainless steel braided. Original Dunlop hose NLA
Hose in the boot is cotton/nylon braided Ditto NLA
Also suitable size rubber boots over the ends of the hose , contains braided hose ends
Also some excellant stainless hose clips. All prices seem Ok
