Do i have to run with a high flow fuel pump like a holley blue or could i get away with like a mr gasket 12s ? im asking because for one i have had a holley blue before and they are quite loud compared to the mr gasket that you can pick up from the auto parts store, also the mr gasket is a third of the price and i wont need to run a regulator. just curious, by the way its a stock ls 2

I wouldn't waste my money on one of those Mr gasket pumps the only real advantage you would have is that you could take it back to advance auto or autozone or... when it craps out. Get a Carter rotary if noise is a main concern also the price isn't bad. I couldn't sleep at night with a cheap Mr gasket pump on my car... but thats just me.

The Mallory pumps seem to be quiet when used in a return style system. I loved mine.

I have a Holley HP 150. It's not cheap but feeds my 600 hp motor.

I have a Mallory Comp 140 with their matching return style regulator. At one point I ran a generic 140 gph Summit pump when the Mallory unit crapped out. I didn't really notice a difference between the two pumps. The Mallory was a gerotor design and was suppose to be much more quiet than the rotary vane summit one, but in my case there wasn't much difference.

I will say the larger the pump is the more noise it will make. What is your projected HP? If you are anywhere near stock HP this summit pump will work with no regulator

A number of guys running the Carter pumps claim they are pretty quiet. Not a bad price either AND I think some of the chain parts stores carry them.

For now the motor is stock and at 400 hp, in the next year or so I may port the heads, cam, and headers so then I would be around 500 ish. Are there anythings I can do to help quiet the pump a little more like wrap a strip of dynamat around the body of it or would that make it run hot

That 95 gph summit pump, or one like it, will be more than enough for your motor.

sound deadener will help all the way around. so will mounting the pump with rubber mounts. Keeping the pump low, near the bottom level of the tank, helps. With mine believe it or not switching to a low resistance prefilter helped quiet things down.

I wouldn't get too worried about pump noise. My set up is about as bad as they come, small car with all sound deadener removed with oversized pump mounted pretty rigidly, and the noise on mine is there but not what I would describe as bad.

If you really want it quiet an in tank pump is the best bet. You can run a fuel inject pump like a walbro or bosch, just use a carb type regulator with it.

Would I need a baffled tank with a in tank pump ? Anyway I picked up a 105 gph pump with a return style regulator, it's made by mr gasket but looks like a direct copy of a holley blue. Was going to go with a holley but got this setup off a guy who changed directions with his build, it's new in the box and I got it for less than half the price of new so gonna give it a shot. Thanks for the replies

If you plan to race it something like that never hurts. But with a carb you don't have to have it.

The summit pump I have looks exactly like half a dozen other name brand parts. If they aren't rebadged units then they sure as hell came off the same boat. If the one you have dies then get a name brand.

Thought mr gasket was name brand, they make accel and Mallory products...

i ran a 12s on my el camino, and when i had issues(ended up being the cheap regulator), i changed to a carter. the carter is/was a nice unit, but much louder, you could barely hear the 12s(which i still use as a transfer pump around the garage). i've heard bad things and good things about both, its all preference and what products you have good luck with.

So I ordered a new tank and sending unit and the sending unit only has one tube, the regulator that came with my pump is a return style regulator is there a way I can use this or am I just better off buying another regulator ?

Lots of guys run deadhead regulators but return styles will keep the noise down and make the pump live longer.

I added a larger return line to my stock tank with a bulkhead adapter.

BTW, I looked at Mr Gasket pumps and they look exactly like the summit one I have.

So would I just drill a hole in the top of my tank and install that, then run a 3/8 line from my regulator back to my tank ?

Im running -6 line with a holley black pump and its loud.

Top or side, whichever is easiest. I did use a little gasket sealant on it. That fitting has an AN fitting so I coupled that to the hard return line with a short piece of braided fuel line and some Russel ends.

You need to get a wrench on it from the inside, so install it near the sender unit hole. I ended up making a "wrench" by cutting a rectangle in a piece of wide bar stock.

You could also get someone to weld a bung on the tank.

I plan to run the holley blue on my setup, it comes with the appropriate regulator which is a plus and it has a decent flow rate for what I need.

My fuel tank has 3 vents built into the top of the tank, could I just use one of those as a fuel return line ?

So, Do I need to run a return line?? This is my first foray into carb set ups with a LSX motor. I run the EFI set up in my other cars with a corvette Reg, do I have to do that... Does anyone have some pics of there cars fuel systems??
