Got Mallory Comp 70, need advice
I just picked up a brand spank'n new Mallory Comp 70 and I'm planning out my installation now. I'll be installing a Holley regulator but I'm wonder where I should install a second fuel filter. Should it be before the regulator or after and what fuel filters do you recommend? TIA

I got 2 fuel filters on my car
1-between the tank and my Holley pump
2 inline clear one-on the firewall before the regulator/before the carb.

Put your filter before the regulator, otherwise you'll be regulating fuel into a restrictive filter and catching crud after it goes through your brand new regulator.

Isn't the Mallory field rebuildable too? Or is that the Carter?
Nice location too. Right in front of where the Stock filter goes.
What happens if you change teh filter? Does the pump need primed so that it doen't just spin air, or is it self priming?

So mounting orientation doesn't matter? I thought the beast had to be up and down, course I haven't even opened the boxes to either one of my Mallory's to read the instructions. Hell, I don't even know which garage box they're in.....year and a half later in the new house and I still have boxes from the move...

Glad to be of help and you answered a question for me, too.....I've never actually sized up whether a Mallory would fit back there on the frame rail and now I know....the '83 is getting the conversion in April...

Oh, you little post *****... 
...the filter at the back should be a pleated element style that is really unrestrictive. That means, by design, an element only stopping down to 40 microns or so. The pump has to draw from it. At the carb side, you pull the little filters from the top carb housing and the needle seat barrels, but now that means a filter outside of the carb good down to 10 microns to keep the junk out of the carb itself. If you're still stock, this is all overkill, however. Keep the internal carb screens and don't worry about a second filter...
