Electric fuel pump conversion

[Furyblade_Lee]

Hi guys, I am going to convert my car to an electric fuel pump. Any ideas on which pump to buy, positioning and what to wire it up to? Its an SE5a. Thanks.

Not going to be a great deal of help but................

Can't remember what make mine is but it's positioned on the rail just in front of the tank.

Can't remember where the power came from but it's something that comes on with the ignition

I've got a switch in the drivers footwell air-vent that I use as a rudimentary anti theft device.

Not much help and I'm away until the 6th. I'll have a proper look when I get back if you haven't had a more helpful reply. Or you could try: http://autos.groups.yahoo.com/group/ReliantScimita... If you are a member you'll definitely find the info with a search there.

ETA it's a Facet pump one of the square ones but not sure which.

I guess you're running carbs, so you'll want a carb spec pump (not EFI). The carb spec pumps are much cheaper and also less fussy about having suction on the inlet side, so you should be able to get away with putting it up front in the engine bay if you want. Make sure you fit a shut-off device so it switches off in a shunt. (If it was an EFI setup the pump would also shut off if the engine stopped for any reason, but with carbs you probably won't have an 'engine running' signal available to do that.)

You'll need a pressure regulator, perhaps you already have one in the circuit.

What pressure should the fuel be set at? Sorry but I have not had a 'carbed car for about 10 years!

• *BTW my White Scimitar has been carted off today to be used in filming for a programme called ( I think )"Lewis", which is apparently a spin-off of Inspector Morse. No Idea what role the car will have in the Drama, but it will be away for a few weeks so there could be some good Scimitar action on the TV in the near future!

No idea, it would depend on the carbs. Too much and the float won't seal properly, too little and the float chamber will run out. I would guess 2-4 PSI but you need to know what the carb needs, really. You can find out by seeing how much pressure it takes to overcome the float and make sure you stay well below that - or just ask what other people run those carbs at.
