Walbro In-Tank Fuel Pump

I've been doing some research as I think my fuel pump is slowly on its way out. Sometimes it doesn't prime when opening the door, feels a bit slow every so often. I'm getting a list of all the parts I need for my stage 2 and I think it would be wise I upgrade the almost 100k miles old fuel pump with a shiny new one.

I've read that either getting an LCR one or a Walbro 255lp/h in-tank pump will be good. I'm inclined to go for the Walbro due to it being a lot cheaper for a new unit but have read about fitment issues. The Walbro seems to be a smaller size to the OEM and either need to butcher the housing or getting an adapter.

The threads I've been reading are a good 3-4 years old now so was just wondering whether anyone has fitted one of these recently, whether they'd changed the design etc? I think I'd rather get an attachment/fitting kit instead of modifying the actual housing just for peace of mind but wanted to get other peoples views on this if possible.

It's probably the door lock switch causing it not to prime, rather than the pump itself. I bet the interior lights dont come on either when that happens...

I can't really help in regards to what pump you could use as an upgrade, but if it was me and i was planning on chasing big numbers i'd be inclined to use a generic in-line pump that flows well and leave the tank pump as a lift pump.
Door module is fine. Was replaced about a year ago with a new oem unit and lights come on fine.

Not planning to go for big numbers for now just a stage 2 with a KO3s just thought I might as well future proof myself a little in case I go hybrid or BT in future.
I'd get the Sytec FSE P3031.1 pump, ideal for stage 2 and beyond, and is a direct replacement for the std one.
What sort of power can it support as I'm looking to go around the 300bhp mark
I think the walbro was good for 500bhp+. I'll definitely look into the Sytec. Do you have this?
I have it and have been told its good enough for a hybrid. So your looking maybe 330--350 max out of it, but its easy fit and forget.

It may do more, tbh not sure, but that will be max I would want so not looked any futher
