If I remember correctly I think John Hertog used an inline electric pump that was oem on an early 80's Subaru which was carbureted. I'll have to do a little research Mike Laiserin In a message dated 6/26/2010 8:15:19 A.M. US Mountain Standard Time, retromobilia@xxxxxxxxxxx writes: High pressure pumps (which at the moment are the largest supply due to modern fuel injection cars) require a pressure regulator and a by-pass and/or a supply back to the tank. This makes them and the use of a full time pump on our old cars with carbs (especially twin 4V carbs.) very risky. A proper 5-6 # old type pump, if still available, are very expensive.

Should I assume you've all chosen a low pressure pump of some type since there's no regulator? I've got a high press pump on my Fueli K which I'd be afraid to put behind carbs... I think anything more than 5-6 psi would blow the needles off their seats and overfill the carbs Mike Laiserin [Non-text portions of this message have been removed] ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to: Chrysler300-unsubscribe@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/Yahoo!
