classic mini spi / mpi in tank fuel pump replacement

Hello and for my first post I thought I would post a guide on how to fit a Walbro in tank fuel pump.
We had numerous problems with the original pump cutting in and out and a replacement is £160+ here in Scotland , this was fitted to my 1997 Mini cooper 1.3 MPI . So we decided to fit an Original Walbro pump (£70) (Made in the USA).
This does require some Modding but its very simple and straight forward. I got my dad who has been a mechanic for over 40 years to go through the process and i photographed the stages.

The first thing is to either drain the tank or run it as low as you can. Then remove the tank as per the haynes manual then remove the pump assembly from the top of the tank.

Remove the old pump from the pipes doesnt matter if you break the clips as you wont be reusing.

Dont tug like hell at the wiring the clips must be removed in a specific way

Using a pointed tool put it in the small hole in the clip to release the locking tab as seen above

Unlock both tabs and remove wiring

The clips are of 2 different sizes the positive is the smaller clip (red wire, left in the image) . The earth is the larger (black wire,right in the image)

Now using the Supplied wiring loom solder the clips onto the correct wire

Now connect the new wiring loom to the pump assembly, Remember small connection is red wire and black connection is the larger clip

now wrap the wiring around the Fuel feed pipe and remember to slide the sound insulation sleeve up the same pipe before fitting the actual pump.

Now a small modification must be made to the fuel feed pipe to allow the new pump to fit.
Cut it just above the small brass ring

This allows the new pump to fit with its small piece of tubing supplied in the kit, so fit the pump with its tubing to the frame and to the modified feed pipe and remember to put the rubber boot onto the pump.

Once this is in place you need to fit the filter strainer to the bottom of the pump but further mods are required to allow the filter to lock on
you must cut the bottom bracket to allow a better fit using snips

push filter till you feel it lock , now place the small locking ring on the back tab and push into place using a 5mm socket

now lean the assembled pump into the tank

and Job done !

Now just fit the nuts and put the tank back into the car as per the haynes manual remember orange tagged hose to orange ring on the tank!
The pump is extremely quiet in operation and be careful of fake walbro pumps ours was purchased from Driven2automotive on Ebay and on on inspection is the real deal
