I have an in-line filter at the pump (last 10 years) My glass bowl has been empty (no filter, 20 years)
So at last I fitted a filter. Blasted bowl wouldn't seal, 15 times later, I'd had enough!
Put the bowl together, without filter, sealed 1st time! They knew something 20 years ago?
So, I know this is the correct filter (from "SNG- Barratt" )
Obviously the filter creates too much pressure?
And, yes I had the open end of filter to the top, fits right on?
Any ideas! David
I just noticed, I didn't insert the spring into the filter at the top??

 

In 1968 Jaguar issued a technical bulletin replacing the screen filter (not visible when bowl is mounted) with a filter often referred to as a bunt cake as it sort of looked like one. The screen must be removed. As to the filter you put in if it had a spring it is the wrong filter. The correct filter simply slips on the pipe stub and holds itself. Fuel should flow from your pump through the middle of the filter to the bowl (there should be a hole through the entire filter) and then filters on the outer portion to your engine. The incorrect filters with the spring try to filter through the inside which will function but will clog quickly and the bowl will look fine. Best of luck.

The difficulty you had with a seal leads us to think you did not remove either the old screen or the old gasket---or both.

 

Here's another thread on the matter.

The filter in my link is what's described in post "2".
The paper end of the filter is simply pushed in place on the pipe stub.

Sometimes it even comes with a gasket, it doesn't, I use this neoprene/cork gasket material to make my own.
A Dremel tool works well here.
