Anyone any ideas what a 101 Fuel pump uses electrically ? I have a 101 club member, with a 24 V system feeding a 12V pump via a resistor - which is getting burning hot. He reckons yon pump is pulling 35 Watts ! Thanks

Assuming it's an SU that sounds about right from memory.
/5 minute break
.....and is borne out by a quick test of the SU in my neighbour's MGB.
WOW. I never expected that from the kind of flowrates and heads involved.

I don't think energy efficiency was a design criterion! ('bout what I would have expected) JD

If you go here:
I've just been through this process buying a fuel pump for a Jensen. It was a cube type pump that flowed a maximum of 34 gallons/hour and up to 10psi maximum pressure. Currant consumption was 1.6 amps IIRC.
If it is 'pulling' 35 Watts, through a dropper resistor, then this too will be 'pulling' 35 Watts. So, if it's not a big ceramic wire wound thing - like they use to slow up heater fans then it will be burning hot!

They claim about 1 amp somewhere else in the blurb. This is for the current day solid state interrupter pump. The older ones as on the RRC, and I presume the 101, were much less efficient and 3.5 amp. or thereabouts at full chat does not surprise me.
