Thank you all for helping me out with the parts I require to carry
out a Bosch conversion on a TR6 PI (especially Graham Stretch &
Jean Roulleaux). I now have virtually all of the bits required to
do the job (with the exception of the fuel hose and one banjo bolt)
and intend to convert from the Lucas fuel pump to the (hopefully
better) Bosch. Bits I will use for this are listed below:
Bosch fuel pump - 0 580 254 927
Bosch Fuel Filter - 0 450 905 401
1x 14x1.5mm Banjo Bolt
1x 14x1.5mm Ring Nipple
1x 12x1.5mm Banjo Bolt
2x 12x1.5mm Ring Nipple
1x 12mm Cup Nut for Fuel Pump
1x Fuel Strainer
What bits go where? Well, if we start with the fuel tank we go:
Tank -> Strainer -> Fuel Pump -> Fuel Filter -> Pressure Relief Valve
-> rest of original injection system.
The two banjo bolts (one 12mm and one 14mm as well as the two
matching ring nipples) go on the fuel filter, while the remaining 12mm
ring nipple goes on the business end (outlet) of the pump.
I'm thinking of mounting the whole lot in the spare wheel well, with
strainer below the fuel tank, the pump on one side, and the filter
on the other (where it is currently on my car - not sure if this is
original or not). This should give me slightly more boot space (and
I won't have to worry about plastic stuff in the boot melting on the
fuel pump :-) ).
Once everything is mounted and up and running I'll put some photos
on my website (once I work out how to put some info on my webspace at home).
Guess that's it for now...

Hello Frank,
Following your request yesterday I visited a friend who is running
a TR tuning shop to find out what is the best pump to operate the
Lucas fuel injection system. By coincidence he was just fitting a
new Bosch pump to a TR6 retaining the original CAV filter. He said
that this pump is working very well with the original filter.The pump
Nr is 0580 254 910. He moved , as you also suggested, the filter
to the right side of the wheel well and fitted the pump as low as
possible in the left corner where the filter was located. We checked
the pressure at the metering unit at it gave a very stable 7 kg/cm2
In this case no pressure filter is required.
Good luck and regards
Jean Roulleaux
