Bugger, not a quick job to replace, assume same joys as a vx220 with seat out and above acees with small mod to hatch or drop tank. Failed fully or not handling load?
Option to use oem as pickup pump and get a nice swirl pot and man pump in engine bay?

Yeah, not a fun job.
It’s failed full stop mate. Nada, nothing , zilch. Let it cool for a bit then possibly work for a second or two but not really enough to keep it going.
It has a Gucci pump in it at the mo. Will let RSTuning do the diagnostics and then work from there

They know what they are doing but impact switch and fuel pump relay worth checking 
had a few interesting ones historically

Gutted for you buddy..
Is this the time to wire and plumb
an inline bosch 044 and not even worry about the tank one..?

Yep
What I did on a lot of high power/track vx220. It's this or upgrade oem options but if oem dead labour pains

Relay ok also?
Yeah, can hear it click mate. Literally ign on. Wait, click. 5 seconds , click again.
Every 20th time you found hear the pump prime.
I have a 6month old 350mi new pump in. Just going to validate it’s not wiring first then return the pump if not and replace.
If I had of been out of warranty I would have opted for a external pump option I think .
What a shitter. How was it going before that let go?
Strangely TBH. I was actually down on power prior, but not by a lot. The investigation was halted though pretty quickly due to this!
We appear to be back in the game.
The MFRU was causing funnies. Specky @RSTuning was looking at fuel pump voltages and it was " all over " and then sometimes not enough to even switch the relay on for the fuel pump.
Some brief investigation followed and we worked out its the MRFU thats at fault. Look at the symptoms ;
Fuel pump mostly failing
Lambda sensor not reporting correctly
Two of the three things the MFRU is responsible for ..
Investigation has led to corrosion and decidedly second hand wiring in that neck of the woods and its been tidied up ( for now ) to get it running, mapped , circuit ready for BH Monday @ Anglesey. Ill do the usual throw some cash at the issue over winter to properly inspect everything.
I also suspect as the fuel pump voltage was all over it might explain the drop in power initially.
Roll on the mapping!
Big thanks to Spitfire ( Gaz ) for being super fast at replying and offering to swap my pump out whenever needed.
Huge thanks to Paul @ RSTuning for squeezing my car in to get me up and running

make sure you get plenty of footage
Car is back home.
Nothing at all really to report power wise after the parts were fitted. Power was roughly the same ( taking in atmospherics / temps etc ) and its gone from narrowband to wideband.
My arse dyno cannot tell the difference other than the car appears to be smoother. This could of course be down to a questionable connection to the MFRU.

Twinguna Turbo levels of insane acceleration..
