The pommy 850 eng 8AM/U/H105739 I picked up with the mini bits has the fuel pump hole blanked off with a plate. It looks original as the engine/box is complete[even has a cast iron water pump]
Did the early cars have electric fuel pumps, as I thougth that they had mechanical.
This eng is about 10,000 earlier than the no. stamped on my car. I know that mine is a Austin that was built in England in the 3 week of nov 1960. The original eng had nothing fitted to the hole. that is what filled it with water

Yes, here in Portugal early 850's ( imported from UK ) had electric SU pump, i bought a 64 one for spares and it had it under the fuel tank.

8AM is a early Morris engine. They had electric SU fuel pumps mounted to the rear subframe.

I believe they changed to mechanical pumping when they went over to negitive earth, my 67 UK van has/had a blanked off pump hole, and an su pump on the rear frame, as part of its negitive earth conversion at some stage, the pump was isolsted from the bodywork with rubber.

speed costs....how fast do you want to go...

All `8AM/U/H' 850 motors in Australia got an electric SU fuel pump.
PD type, non-repairable. I often used to have to stop, walk around my car and give it a `swift kick' to make it work.
These were not the most reliable fuel pump ever made...

SU elec pumps were fitted to all Australian Morris 850s. The pump can cause problems but they can be rebuilt and with maintance they last for years. Very eary 850 engine blocks have the "850" cast in a different spot on the back of the block. All 850 engines had a blanking plate where the fuel pump would go, later 997 coopers, S motors and some early M1100 blocks had the casting left un machined.

The old `PD' type pump on early 850s was not repairable, all we could do back then was clean the points.
Later cars got the `AUF' type as fitted to Coopers. I didn't mean to imply these were no good or couldn't be fixed.

Both my first (1964) and my current (1963) had/have electic pumps Don't know what was in my first one in 1967 but the current one is original (date) and it was made in NZ and not an SU - by body number on the plate the car was a CKD kit so don't know if the pump came with the car or failed and was replaced very early in it's life.

My greatest fear in life is that when I die my wife will sell my Mini and tools for the price I told her I paid for them!

thanks guys. that has solved another problem. My 60 car obviously had the fuel pump changed to mech at some stage. Lucky I have two elect. NOS ones in these bits.
I have found that there are many parts for 59 cars in this lot. They are going to england for resto jobs. I wonder where these parts came from?
I am waiting for pics and details on the parts that are suited to the 59 cars. The two dist. were purchased by a bloke in england. when I sent him the No's and pics, the 7/59 one would have been fitted to one of the very first cars made. at least they are going to be used and not end up in the scrap metal.
