Re: dual action fuel pump
LC,
The early pumps have the small mounting face whereas the 8ba pumps
single or double action pumps have larger (longer) mounting face. The double action pump
versatility comes at a price, in my opinion, that price is a very stiff action. Speaking
for myself I cannot actuate a freshly rebuilt pump by hand. Often times when
I get a car so equipped in the shop I find the push rod is bent. JMHO !
