MC, a-1000, aeromotive, .5 line to the front, areomotive regulator,(the one that looks like a red and black minion) .375 lines to the carbs(2 750 eddys), plenty of fuel to go around. Dave.

How noisy are the black pumps on a street car Ron? That's always kept me from running one.

They are a little noisy. If you mount it with rubber under it that helps make it less noisy. But it will still be noisy some. It don't bother me because I grew up where most all electric pumps were noisy and we listened to hear that pump run when the key was turned on. If I don't hear it I know the pump is not working and something is wrong. I guess that's why a little pump noise don't bother me at all as I wanted to hear that pump working. But I can also understand why many cant stand the pump being to noisy. I have run the Holley red , blue and black pumps and I have had great luck with all of them. The black pump on my car now has been on it since 2011 and has been flawless with no problems at all so I like how reliable the Holley pumps have been for me. Course it is nice that you have a nice selection of good electric pumps to pick from today. Ron

I'm sure I'll be told this won't work, but I've used the same set-up on our 600 HP, N/SS car (10.80 @124 in a steel, '63 Plymouth), and in my street/strip Road Runner (11.07 @123). I use a 3/8" aluminum line from the tank. At the stock tank there is a Carter electric pump. That pumps to a Carter mechanical pump in the stock location. I have a hair over 6 psi from idle to 6500 RPM. I was told by a savvy old stock eliminator racer that this set up will work down to near 10.0 territory. Haven't been nearly that fast! The system in my street car has been in for 15 years with no problems. I don't use it all the time. When driving around town, it is usually not needed, and the mechanical pump pulls through the electric pump. If I'm pulling a hill or driving hard, I turn it on. I could run it all the time without incident, but feel I'm saving it the more it's turned off. I have a switch under the dash for the electric pump. Good luck.

I only run the Holley black pump but I use a stock gas tank with the pump mounted right in front of the gas tank by the sending unit outlet and I use a stock type 3/8 sending unit and I have 3/8 line up to my carb. I just always try to make sure I have a 1/2 tank of gas or more when I go racing and I have never had any fuel starving problems. Ron

I use a product engineering pump system. I was originally planning on aeromotive but when i talked to the tech guy, they said I had to mount it below the tank and they really didn't like the idea of running it consistently on the street. When i talked to the guys at product engineering, they told me it was made to support any motor, be it in the street or track and if i wanted I could mount it on the roof, it'll suck fuel virtually anywhere. I think the pump is pretty great, rock solid pressure that seems ultra stable no matter the throttle position.

Now the down side... their regulators SUCK! I'm not sure if their regulator could regulate a factory mechanical pump. And as a band aid to a shitty reg, they sell you this junk bypass system. I've had nothing but issues. Got a new magna fuel reg now, just haven't had time to try it yet since winter set in.

The pumps are great, John the tech guy is overly self righteous, Chris (new owner) seems pretty great and always trying to help. I just wouldn't buy the whole system.

U summed that one up, MG.
Mopars don't use Nitrous, plain and simple.

That is because most already cried & complained how much money it cost them to build their engines so they don't want to take a chance to hurt them. If tuned right you can run them forever on nitrous & not hurt anything. I have a lot of money tied up into mine and we are still spraying it.
 
I use a carter 4600HP electric pump and a carter 6903 Mechanical in series. 1/2 line, including the stock tank pickup. The electric pump is on a switch and is only used as needed. I wasn't sure if the mechanical would pull through it reliably, so I ran a bypass line with a one way check valve around the electric pump. It's a relatively low buck setup, but I doubt I'll ever outrun it.

That'd be a good setup, hooked to a WOT microswitch.
 
I run a magnafuel 300, 2 years ago it started leaking during a race at Norwalk. I put my spare aeromotive ss deadhead pump on and saw zero impact to ET or mph. My car runs 10.50 @ 126. Most important is how it’s plumbed from tank to carb.

The mechanical pump will not pull fuel through that pump. I run the same setup (72gph pump) no bypass. Was up in Mass. an a wire came loose, car stopped. Went under car hooked wire back on with a quick tape job.

Judging from all the different posts the brand or type of fuel system is quite varied. What works for one doesn't necessarily work for all so the parts manufacturing industry marketer's are doing their job, offering choices!

I will just add I have a magna 500.You can never have too much fuel pump. -12 from tank to pump,,-10 from pump to 4 port regulator and -6 to each bowl.
