TR4/4A Fuel pump saga

I decided to post this so that others don't waste as much time as I have.
The pump was overhauled a bit over a year ago.
It had always leaked out the inlet pipe junction so I purchased a new pipe and olive (Furrule) from Rimmers about 3 months ago.
Installed it the recommended way by pushing the pipe in as far as it would go then tightened the nut.
No more leaks from the inlet.
A few weeks ago the car wouldn't start, I traced it to the fuel pump, replaced the 18month old diaphragm and put the pump back.
Tightened the inlet then the outlet, the 60 year old threads finally gave way on the outlet , stripped.
Removed the head then tried unsuccessfully to tap them.
Purchased a new pump and decided that since alot of people have had issues with them I'd use the new head on the old body.
I couldn't separate the head from the body until I shoved a knife between them, damaging the diaphragm, but that was ok as the old pump had a new one.
Screwed the new head onto the old body. lo and behold both pipes leaked.
Tried tightening up a bit more but didn't want to damage the soft metal, still leaked.
Went inside and had a lie down to destress.
Went out later and wrapped the olives in solvent resistant PTF tape, no leaks.
I'm going to replace the existing olives.

Someone up there is trying to send me a message as if it can go wrong it has......

^^^ That did it for me. I just used emory cloth to file down the olives so that two of them together are a bit larger than one.
 
Thank you for the replies. New Olives it is. The inlet pipe and olive were new a couple of months ago so I'll probably follow Randall's advice.
