Something along the lines of this is the go....
http://www.ebay.com.au/it...ksid=p3984.m1423.l2649 Webers and most carbs do not want much pressure... only a couple of PSI 2-4 generally ... Anything more than about 6 need a reg.... 75PSI is a fuel injection type pressure and WAY to high...
Too much pressure and it will flood or worse leak and we all know that the dizzy of a Pinto is perfectly positioned under the carb to burn/vaporise any leaking fuel.... (What sound does a dog make ??? )
I am sometimes wary of sites selling/promoting particular types of pumps and bagging others. The little facet type pumps do NOT deliver high PSI - IF you get the right one... I have used these on a number of cars for years and only had 1 failure -and at around $50 from most auto shops are a bargain and I keep a spare in the spares box....
