Fuel Pump Module

Fuel Pump Module
1994 Jaguar XJS 4.0 /130k and still going
Revisiting this topic... I have a fuel pump module with a worn out valve. See photo.
It is clogging up the screen on the pump itself. The orange rubber in the check valve is no longer usable. Is there a specific valve I should use in this location. It seems the cheap check valves have too much resistance. I can barely blow air through the one I have.
Is there a way to just do away with this entirely and go with an external pump? Has anyone done this on a facelift?
The dog is as confused as I am. She thinks its a snack:

figuring this all out. Where I am currently at is it possible to buy a replacement gromment for the fuel pump to the fuel pump module (circle at the bottom chown in photo)? Mine is falling apart and its just a matter of time before it starts clogging the fuel pump screen again. I suspect ethanol in fuel these days.
I keep leaning towards going with an external pump and running an R10 hose down into the module. Maybe this is the best long term solution.

I am no expert on the in-tank pump. However, if the pump itself is working and no replacement parts are available for the valve, you could definitely fit an external check valve in the pipe between the pump and the fuel rail. The nearer the pump probably the better. Summit racing etc have them, but buy a decent quality one.

thanks, I just purchased one with good reviews.
The pump is relatively new. My only concern now is the dried out rubber holding the pump in the module. For now I am just going to put it back in there. Eventually I may go with an external pump, get all of the rubber out of the tank with some sort of custom set up and upgrade the hoses to R10.
I plan on keeping this car for a while. Its a daily driver. One day it will be electric, when the bottom end goes on the engine.

For now I went with this, which I am thinking of putting in the tank itself. Any reason why this is a bad idea? I think it will just fit with a couple bends.
I heated the tubing and this is as far as I could get it on. I plan on clamping the very end (closest to the valve) to ensure it cannot pull off.

I cannot see any reason why not to put the whole lot in the tank and that would be just about identical to the original setup. Of course if there is a problem you will not be able to see what is wrong. You could perhaps try it outside first and see if it works OK? The check valve is nicely close to the pump, which is the main thing.
