High capacity fuel pump

I have a Mike Satur high capacity fuel pump that came with a box of MGTF bits and bobs I got cheap.  The pump is new and still in its box.  The question is has anyone had any experience using this pump kit?  Do I need a fuel regulator that Mike sells or will the high capacity fuel pump kit be a suitable replacement for the original fuel pump that has failed.  Mike appears to be on holidays and is not answering emails.  MGTF 160 (2002).

The standard regular should be fine, possibly on its limit but fine, however a reasonable adjustable pressure regulator is available at a price to interest. I was asking to modify a system for a chap, it’s not a one out one in, not the one I have experience of at any rate. As the supplier of the original unit “misplaced” the initial order a second was sent, shortly after both arrived by the same carrier & so I fitted the supposed replacement to my car.
It looks nice with its silicone damped gauge & having mopped up the petrol after a jubilee clip failing, I found not the slightest difference, but as I say, it looks nice.
There is/was info on the net giving a modification explanation, let’s hope it hasn’t gone due to the demise of the other MG site.
(Pssst I’ve forgotten which one it is, it’s an age thing, don’t tell They might think I’m loosing it)

In motorsport there tends to be two types of modified fuel pumps.
The high capacity ones tend to be the same delivery pressure but are capable of more flow.
The high pressure ones deliver higher pressure that needs to be regulated to suit the carbs or injectors.
Hope this helps.

My understanding is that the Mike Satur offering is a fit and forget direct replacement for the OE fuel pump,

I would go along with that.

Why would it be specific only to competition cars..he wouldn't sell any..
