i'm going to be getting a holley electric pump, most likely blue, but right now i have an intank pump with a regulator in the engine bay. so i need to know how to make a pick-up for in the tank for when i get my electric pump. any ideas? thanks

They make carb style pickup for the tank. Is this for a Carb setup because a holley blue is a low pressure carb pump

My question, along the same lines, is it better to just run a fuel cell? (I know, rear fire wall). I'm going carbed now, so I'm looking at the different opions, as well.

my bad, i'm carb'd. i think the blue will work well with my set-up. currently i am running a stock intank that pumps 130gph(i think?) through the regulator, and we had trouble getting fuel psi down to 6. i am needing it a bit lower for my next toy that will be going in the car in the next couple of months.

timido, do you know where i can find that pickup?

I've been looking for one for my car.... I think you can modify the stock pickup to work with a piece of hose.... I'll let you know in the next few weeks or you let me know....

Here is what you guys are all looking for. http://www.jegs.com/webapp/wcs/stores/servlet/product_10001_10002_18230_-1 It just so happens I have a used one sitting here. First $60 can have it.

The size of your return line affects how low you can get the pressure to drop. That electric pump is giving a lot more supply than you need, so you need a bigger return. .02

Zach here is some very helpful info on setting up a fuel system. http://www.centuryperformance.com/fuel.asp

Yes that Fuelish webpage is some very good reading. It gives you a good idea on what pump and line size you should have. I have a dead head system on my car with a BG 180. On my nitrous side I have a Dead head system with an air bleed with a holley blue and a 2 quart fuel cell. I like having the fuel cell on my car with the spare tire well cut out (Flat floor).

ok so on that page, the HP numbers are crank, right?

this may be a stupid question, but i just want to make sure.

I think they are crank numbers

that's what i was thinking. i don't think wheel numbers would have an effect on this type of thing, but i just wanted to check

so i'm looking at this fuel system page and slowly figuring all of this out.

my motor has 420HP at the crank(i will be putting a 150 shot of nitrous on it, which is the reason that i am upgrading my fuel system). so by the example of finding "free flow" mine would need a pump that could give the motor 76gph free flow.

i would need 1/2 line into the pump and for the return.

does that sound right?

the holley blue has a free flow rate of 110gph, and the red has a free flow of 97. which one would work best for my set-up?

I would just go with the blue over the red. I little word of advice as well look at the Mallory pumps they are just as reliable and quieter. 1/2 in line equates to -8 feed and return. Also is this car regular street car or a drag car. If it is a street car you should really consider using a return style regulator. It will take alot of stress off the pump which will help it run cooler and last longer.

Also you really cant overdue the fuel system. Go with as much pump as you can afford and use a return style reg like the others have said.

it's basically just a street terror lol. i currently have a mallory return-style regulator on it that i will continue to use with the new pump.

thank you all for the help with this.

ok. so the fuel pump that i am getting has the 3/8 inlet/outlet, but i will be needing 1/2(which may have). do i need different fittings for the 1/2 inch line?

this may be a stupid question, but it's important lol

You need a 3/8 npt to -8 fitting on each side of the pump. What you really need to do is map out your fuel system from the tank to the carb. It helps to actally sit down and write it out on paper so when you go visit Craig at Cincy you will know exactly which fittings you will need. You also need to decide what type of line you are running as this will determine the fittings you need. Trust me when I say it will take you more than one trip to the store get all the fitting and line you need. Good luck and see you tomorrow.

Thats what I did for my Nitrous System. Craig took the time to draw out on paper where it all should go. Then I bought a box of fittings and lines and went to work. My new radiator has -16 ends on so guess what I am going to stop by CincySpeed and get the big ends and line.
