MG MGA - banjo bolts

As I had a leak on the fuelhose near the carburetter I took everything apart and replaced the hose. After reassembling I noticed that there was a leak on the banjo bolt, although I replaced the washers (red fibre). Is there a magic solution to have this really closed? Even after several times of taking the parts out and cleaning them, there is still a leak! I dont like fuel on the exhaust. Many thanks for any advice

Fiber washer AUC-1928 must be installed in a specific way. It’s #70 in the SPL illustration facing page D4 here - http://mgaguru.com/mgtech/books/spl/spl_1500_d.pdf

Whilst some may sensibly advice against it, when I had a similar problem, I tightened mine more, and more and then even more. Fortunately in my case, nothing broke, and the leak stopped.
I am just wondering if something like Hylomar Universal Blue might be a safer option? Others more experienced than me, will probably give you advice, but if you do try Hylomar, dont put on too much as you dont want it seeping into the fuel.

I find good old soap is my friend for sealing these up
If you get some soap and work it into a paste a bit thicker than toothpaste thickness
Loosen the banjo nuts off enough so there's a gap, let the fittings dry if they have petrol on them , then push the soap in the joint either side of the fibre washers, making sure you get it all the way round, you can spin the fibre washer around to check and help it spread, but not too much to force soap into the banjo itself then tighten it up and wipe the outside clean, just leave it for a few minuites to let the petrol fumes do their thing to the soap and 99% of the time it will be sealed up nicely

I would be very wary of using any sealant in this area with petrol as it could cause more problems. I speak from very painful experience,

Which banjo bolt?

Have you got the banjo the right way round?

Thanks for the advice.
I suppose that I was a bit to cautious with the tightening of the bolts. For the moment all is tight and no fuel is leaking !

may need to smooth the banjo faces on fine emery.
should not need to over tighten
