Hi
my 3500s had an electric fuel pump fitted when I bought it last year.
it promptly pushed fuel past the carbs and ruined the driveway
ive now changed it and fitted a regulator, I didn’t have a mechanical pump, it had been removed
so no choice but stick with the electric, personally I’d stick with the mechanical one at the end of the day it worked when new
so refurb and carry on
hope that helps
regards paul

I have a Huco 133010 sucker pump fitted in the engine bay of my 3500S feeding the 2 SUs, with no issues at all. Quite a few 3500 owners seem to use this pump without issues. Dont have a regulator fitted. Fitted up front, it leaves the reserve system intact. Fits 5/16"(8mm) hoses.

I have a Facet fitted to my 3500S. You should have a pressure reducer in line. I fitted my pump on O/S wing t front, and too the feed from the reserve tap, using flexible hose.. For safety, you should have an 'impact cut out' fitted to the electric supply line, so that the pump shuts off in an accident. My electric was taken from Ignition controlled supply with an in-line fuse before the cut-out.
The pump in this position needs to be a 'long suck, short blow' type.
Mehanical pump can be removed and replaced with a blanking plate, available from Rover parts suppliers.

This thread is on the 4 cyl engines, so i pressume that the OP is refering to the 4 cyl engines, not V8.
As far as i know the mechanical fuel pump on 2000s and 2200s don't give any problems at all, so why should anyone replace a reliable mechanical pump with an electric one?
When necessary rebuilt kits and even complete replacements are not expensive.

I agree that fitting an electric pump is a matter of preference, and rebuilding manual is also an option, and perhaps we should also note that if an Electric pump fails you are stuck! (I have had 2 fail in 20 yrs) but even so I find the ticking of the electric pump comforting.
When I bought my pump from Facet I was advised to fit a pressure regulator

Fitted electric facet type with inline fuse and ignition switched feed . No regulator used and pushing from under tank to carbs. Not quite cured the dreaded vapour lock issues and I retained mech fuel pump at first but now just electric . Planning on drilling out return line restrictor next season see if any improvements on vapour issues . bonnet are now insulated as far as possible . Still gets vey hot under bonnet so contemplating wrapping headers /exhaust next season too .

I know it is of topic, but Vapour lock can be a real problem with roveV8. I fitted my electric pump to cure the Vapour lock, which it did for a time
Finally cured, I hope for good by following the instructions from Chris York in P6 Club magazine.
I do not think that it is a copy-right issue: make sure that the return hose from the Carburetor tower to the Radiator is clear. In my 3500, the outlet from the Tower was clogged with some muck. Cleared out with a 5/32 drill and the small screw-driver, and o problems since. No vapourisation even in the heat of last summer..
Another point; you might want to put a restrictor in the return to tank feed when you fit an electric pump to sop it running continuously. i used a restrictor with a 1/32 in dia. hole in the return feed, so you get a slow ick from the pump when he carb. chambers are full.
I seem to remember that Facet dealer told me that Facet pups ae continuously rated, so the restrictor is not needed.
I am aware that there are many ways of fitting an electric fuel pump, and I am only offering my experiences of doing so, which achieved is objective, curing the vapourisation nd keeping my 3500S on the road all the year.
I believe that the matter has been extensively del with by Chgris York et al. in P6 Club magazine and it might be a service to have this information available to this Forum.
