[C38] Facet Fuel Pump pressure

[Max Soto]

Dave and Tom,
Thanks  a lot. Now I know that almost any pump for a carburated engine will
work. I wasn't able to find a facet (now Purolator) pump here, so I found
it for $69 on ebay, and Catalinadirect asks $237 for the same pump. That
pump has a filter element on the inside, and I was hoping that it was just
clogged but it was clean.. I wasn{t aware that it also has a magnet for
collecting debris.
 I just took a spare pump that my father has for his old Jag while I get
the new one...
I've been planning to install a outboard prime bulb to my engine, just for
back up, but you know, it was not on my priorities list... ask me now! LOL

Regards,
Max
