ah well, if you do stick with the electric pump there are
standard land rover plates and gaskets you can blank the hole in
the block with.
on coil sprung they have a little chassis with the pump mounted
to it, plus a filter bulb next to it (metal bulb, paper element)
so i guess it would be advisable to fit one of those in line
see through filters if you only get the ticker pump

I used an electric pump from a series 3 six cylinder works fine.
It is possible to fit both the electric pump and the mechanical
pump on the same fuel line.
Either pump can suck or push through the other pump.
The electric pump is wired through the ignition with an
additional switch so it can be activated when required.
This worked very well for the vaporisation problem I had.

Hello I had an electric pump and had been placed by po in the
engine bay Struggled to run well on petrol But I also run lpg So
never got to the bottom of the problem Unfortunately burnt out
due to it being to high up I found out They are great at pushing
fuel but not pulling it New one now attached to the outrigger
next to petrol tank I got mine from simonbbc and had no problems
since

Right, finally got to the bottom of this one. I stuck the
electric pump on (cheap one from Paddock) and it fired up
nicely, which was great. Then I went back to the mechanical one
again. I was able to hand prime it and got fuel into the carb.
Then I turned the engine over and no fuel. Went back to the
hand prime and no joy again, weird! I took the exit pipe off
the pump and it was all working! The pipe wasn't blocked - I
had it routed over the top of the rocker box, and I think it was
giving too much resistance. It must have been just about ok
with the original pump (which I believe was a genuine part) but
the Brtipart and the Bearmach could not drive the fuel up over
the hill. I routed the pipe lower and of course it fired up
fine. A confusing problem!
Thanks for all the advice and tips.

I've come into this a bit late however on the electric fuel pump
question I can recommend a HUCO. They're a German brand marketed
by Weber and unlike Facet, they make a pump suitable for
mounting in the engine bay high up near the carb. I've been
running one on the 2a ambulance in the US for several years now,
mounted on a plate attached to the rocker cover mounting studs.
It was 3rd time lucky for me, I tried the square and cylinder
Facets and neither were successful. Low down mounting wasn't
practical with a twin tank setup.

Hi,
With a mechanical pump, it's the return spring that pushes the
petrol up to the carb. The priming lever compresses the spring,
and sucks petrol into the pump.
If there is resistance on the priming lever, the carb is
empty/low.
If there is no resistance , the carb is full, or the cam
follower is on the peak of the cam ... rotate the engine one
complete revolution, then try again. On rare occasions, the pump
thinks the carb is full because the needle valve has stuck shut.
Smack it with a hammer to jar it open.
I once poked a nail through a bean tin, placed my finger over
the hole, filled the tin with petrol, held the tin over the
carb, removed finger simultaneously with starting the engine.
Petrol dribbled into the carb . Engine ran for a lot longer than
just tipping a thimbleful into the carb. I found that after nine
years standing, the needle valve was glued shut.
Er ... this was not a sensible thing to do.
