[Mgb-v8] Fuel regulator for MGB GT V8

[Jim Stuart]

Barrie-

If you are using the stock MGB SU pump, it is unlikely you will develop more 
than 4 lbs of pressure, which is what the SU and later Zeinith crabs 
required- maybe a touch over with a new pump.

Carter and Edelbrock 4bbl crabs, per the factory manuals, are quite happy at 
no more than  5 lbs.

I ran my Olds/Buick heads 215 10.75/1 compression for over 200,000 with 
stock SU pumps and no regulator, and no problems. Later,
I found my 4.2 was starved at top end flat out with SU pump & changed to a 
Faucet.

Jim
