Electric fuel pump

[LLJ9010]

My restorer wants to add an electric fuel pump (behind pedal board) to aid in starting. I didn't think it was that difficult to start before I started restoration. Anyone's thoughts

Well Sir, I think you've paid for good advice. It's always good insurance and if you don't drive it regularly, it does help with start-up.

My only suggestion is that he provide a discreetly placed on-off switch handy to the driver. I use the ever-popular accessory plug hole under the dash.

I suppose there is some downside to the device, but I don't know what it would be.

Maybe if you told us something about your 356, someone could make a better suggestion.

I have a electric fuel pump on my 912 and the normal mechanical one on the 356. The mechanical does like a little longer to fill the carb so I think to turn it over for longer since my 356 does sit, without use, for 4 weeks between drives. However, once it starts after sitting it then starts very well each time so I don't feel the need to change.

With the 912 I can here the elec pump filling up the carbs when I turn on the ignition and less engine turns are needed to start the car.

However, Max Levell, who specialises in 912 in the uk, told me he has seen quite a few of the elec pumps fail.

I hope this helps but maybe you are talking about an additional elec pump to the mech one?

Thanks everyone.
It's for a fresh restoration of my 62 S90 cab.

Engine has 912 heads, 86mm Nikasil lined alloy mahle cylinders, forged JE pistons



He wants to add as an auxiliary pump during start up. Also stated especially longer start times with ethanol based fuels. However plan to use ethanol free fuel.
