Great thread, I have one showing up this week!

I am seriously considering dumping the a1000 and running this pump instead. Great thread with lots of really good feedback

I'll be running two on my car. Let me know if I can help you guys.

What Holley reg has two inlets and 1 outlet that you guys are running?I am fixing to order the 12-1800 pump and hit a y to feed both rails but i do not see one listed on their website and the wait time is terrible to talk to them.I know aeromotive and fuel lab both have one but dont see a holley listed.

bigd427w · 05-02-2014, 10:36 PM

You can plumb the Holley 12-848 so that one rail enters the "inlet", one rail enters the "outlet", and the return is common.

Holley's literature says the pump is good to 18.5 volts.

i understand that, just asking if anyone used a boost-a-pump on these pumps, and how's it working out?

thefloyd1973 · 05-05-2014, 02:00 PM

Would I run into any problems if the pump is mounted a little higher than my sump? I have a 69 nova with a factory style take with a sump. I was going to mount it on the floor area right behind the take (right in front of the bumper). Will this be ok?

Thanks Al.

So this 12 -848 reg can be run like that without issues? What about the 12-846 reg can it be run the same way?

Bumping this.

1986iroc · 06-10-2014, 03:41 AM

how are you guys mounting the filters to the pump? Do they make a straight -12 to straight -10
Also has anyone ever had problems with second side not coming on? I have thought about running them together don't plan on much street driving, maybe 15 miles one way couple times a month.

Suicidal Racing · 06-10-2014, 07:01 AM

aeromotive makes a straight -12 orb to -10 orb union..its a bitch to find though when searching..i priced it with the reducers and using hose between and it came up to the same amount as just buying 2 of the fittings below and just connecting the pre,pump and after filter as one.

here you go

I'm sure race part solution has that fitting too. Prolly cheaper.

I use a "radius pump fitting". 1 side is a male ORB, the other is male JIC 37*, but the JIC end has a grove for an AN o-ring.

You could just use a normal male to male union and us AN o-rings. The radius fitting is a little friendlier to flow.
