Smell of fuel in the boot
Evening all, I had the fuel tank re sealed and repaired at Xmas. I have re connected everything a couple of months ago and am sure there are no leaks. Despite this I am still getting a smell of fuel in the boot. Any suggestions to possible problems or solutions please. Many thanks in advance.

Which of the many pipes inside the boot did you renew, as well as sorting the tank?
Just a few ideas:
It would be worth taking a very careful look at the filler flexible. This is not easy to connect properly and tighten
Did you use new olives on the connectors into the boot?
If all else fails, then block the inlet and outlet pipes and all the others except one, and pressurise the tank using a radiator pressurising gizmo from some pipe or other and see where it weeps/hisses etc.

Lots of possible sources for the smell as indicated by the various responses. I'd invest in a fuel sniffer like the Tif 8800 to help isolate the source. Very useful and time-saving tool and you can get them used off of ebay for $50-$80. I used one on my XJS to trace the fuel odor source to a wiring bodge through the evaporative flange on top of the tank. Good luck.

the cars with tank and associated parts located outside the body, had little to nothing for oder!,,(altho they had other problems,like crash fires,minor stuff tho LOL.

I suggest taking the tank out. the car s 30 years old. If it ever had moisture in the trunk (boot) and it got under the tank it could deteriorate it over time.
All kinds of hoses and connectors associated with these cars.
Two additional potential sources are the fuel sender unit locking ring not being fully seated and the fuel filter clamps. Also check the 'expansion tank' and hoses located under the battery on my '87

There is a "gator" right at the top of the filler neck. It is fragile (mine was after years of sitting) and I would imagine that part of resealing the tank would very well have disturbed the gator, fuel cap, fuel tank connection... It is ribbed/accordion style and a leak in this is not always easy to see. Ya can't get your eyes around the entire circumference to check.
What might help checking is to undo the bolts/screws that hold the gas cap to the body, undo the clamp (in the boot) that secures the gator to the cap assembly, remove the cap and then inspect the gator cap assembly seal from outside the car/boot.... Just my 2cents...
