Default Fuel Pump in earlier V8s

Geo
Thanks for your contribution, but I am not sure what you are trying to say!
Some twenty years ago I started to 'update' my 383 engine (from 12 miles per
gallon).
I replaced a lot of items and today I am getting 20 (+ or - 2) miles per
gallon depending on the traffic and my temperment.
Remember - the Canadian '383' was manufactured for use in California which
then had very tight emission controls + lead free fuel.
This engine was fitted with a Carter Four Barrel carburettor which met those
emission controls by restricting the airflow through it.
The Four Barrel Weber carburettor allows some 40% more air (cubic feet per
minute).
I have a 360 degree unrestricted air filter + new intake manifold fitted.
No modification to the bonnet is/was required.
The Edelbrock fuel pump was only part of that updating process.
I have three 1950's Carter mechanical fuel pumps which broke down - the
Edelbrock pump uses a different method of pumping and is self regulated at 6
psi as required by the Weber and is much quieter.
Some years ago, the 'leaded' fuel disappeared from the market.
To date, I have not re-tuned for that loss.
My email is jevs@iol.ie if you would like more detailed info.
