I am going to convert to an electric fuel pump, have never been keen on the location of the standard pump, ie very close to dizzy etc. Looking at mounting a new pump under the car around the diff, but space seems a little limited due to the exhaust. In legal terms can the pump be mounted in the boot, as the fuel tank already is?

thats where mine is located, so hope its legal..

Mine too. It's not a problem as far as I know.

Nice set up whools. What brand pump is that and what psi are you running?

An electric fuel pump has been happily tapping away in the boot of my capri for the last 33 years with no ill effects.
There are some precautions to take, I have recently sealed the panel that runs behind the seat back in order to prevent petrol from running in under the back seat if there is a mishap. Also I have the pump wired with its own relay and fuse and the next mod will be a pressure switch which is connected to the oil pressure guage pipe. So when the engine stops for any reason then the fuel pump cuts out too even tho the ignition is still on.

now that i remember, when mine was wired up the auto electrician used a relay that makes the pump run for 2-3 seconds then stop when the ignition is switched to 'on'.
its also wired to cutout when the engine stalls/stops running. I think via the alternator?

My first V6 had an electric in the boot, the noise drove me crazy and there was no noticable benefit. My current one has the standard mechanical. No noise, no extra load on the electrics, no worries about leaks, and readily available ex UK. I would never go electric again.

Same for thermo fan, never again.

Just my 2c.

I think it depends on what you a trying to achieve as I like the advantage of turning on the key & having fuel pumped into the carb without turning the starter but I dont like the noise & I think if you are chasing a particular fuel pressure for performance then go the electric but in most cases the mechanical fuel pump works well.
There are benefits of having an electric cooling fan especially in the really hot summer months in traffic & you also have the ability to turn off you engine & leave the fan running to pull down the temp quicker, but my wifes Capri has neither & my Xp Falcon has both.

As this mod was available in the seventies I reckon its good to have now. Of course everyone will make their own mind up about it but I reckon its well worth while.
Things I like are:
Quick and easy starting. Fuel pressure is up straight away and there is an even flow. Especialy important if the car has been sitting for a couple of weeks.
No vapour lock problems in hot weather, the pump just pushes the bubbles out and it starts.
Pump should supply up to 200hp, which is plenty for me.
Secret switch. As there is a wire going to the pump a hidden switch is easy. That way the joy riders wont get much joy.

One thing that bothers me about a mech. pump is when the diaphram perforates then petrol goes into the sump, that cant be good.
Anyway I think the electric pump is just much more sophisticated and its a mod that can be returned to standard easily enough.

Some brands of pump are noisier than others so it would be worth asking around.
Stay away from the Holley Blue pump which was popular back in the day - very noisy and unreliable. I have read that it is best to rubber mount them to keep them quiet.
I like the idea of the secret switch and the auto cutout is a must.
