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

 

Out with the old and in with the new.

 

Installed

 

pfft, bah, mines bigger

 

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.

 

Nice job, where did you mount it? All i can see in the pic is that theres a brake line next to it.

 

Looks like it's mounted in front of the fuel filter (back of car in front of gas tank).

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.

 

ahh, i see now. Ditto on the filter location. Ive got one of those autozone brass reusable filters before my pump, and then just a regular paper one directly before the carb.

 

Nice, is it noisey? I have a holly pump on my '82 and it is very loud, it is bolted to the sub frame. just wondered if the mallory is any better just for future reference.

 

Mallory is the BEST for the rex... NIIICE and QUIET!!!!


The best way to go..... Ask Mar3 about 'dem nasty carters




Laterz, Andrew

 

Thanks! It's mounted pretty much where the original one was 'cept it's mounted to the underside of the car instead of the plate. I wonder if I should fab a bash plate?

 

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?

 

Interesting take on it and the crud logic seems sound. The interesting thing about it is that the instructions that came with my Mallory says to mount the filter after the regulator. Hmmm, wonder why they say that?

 

Yes, the Mallory is rebuildable.

 

Wow.. responded before I got done editing my post. THanks.

 

It's self-priming.

 

Cool beans.. How much was it and from where?

 

Well, it goes for $149.99 from Jegs but I got this brand new baby offa eBay for $61

 

oooops damn forum

 

Mine is bigger and has more fuel pressure, about 60 at 18 psi

 

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...

 

Boy I'm glad you mentioned that Mar3. It got me think'n so I emailed Mr Gasket (aka Mallory) and they said that it definitely has to be mounted vertically. So I remounted it on the vertical frame member. Fits pretty nice actually.

 

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...

What benefits/results have you had from the second filter??

 

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...
