I was wondering if any of you out there is running a in tank fuel pump to support a carburated 550hp LS2. I am putting one in a 67 camaro and the only ones for a camaro I can find is the EFI high pressure ones. Is anyone running the in tank EFI pumps and regulating down that much. I need about 8psi. If this would work I dont know what gph pump I would need on a high pressure one to support 550hp. Any info and help would be appreciated. Thanks.

im currently running a stock ford intank pump in mine with an A1000 carb return style fuel reg on my carb setup

with the right regulator and correct fuel line sizes it shouldnt be an issue

I looked up the a1000 regulator on jegs and it said it adjusted from 30 tp 70 psi. Did I look at the right one. I need to run the carb at around 8psi.


I think I may have found it. Summit has this one that looks like it will take high pressure down to carb pressures. http://www.summitracing.com/parts/AEI-13301/. It the only one that I found that say it will do this. I am still not sure on how many gph pump I would need.

I was told(can't remember by who) that this Holley regulator would work to bring down EFI pressure to carb pressure. I also read it in a few places on the net. I believe one guy on thirdgen.net is using it on his formerly TPI f-body.

I bought it already, but we haven't tested it with the stock LS1 fuel pump yet.

I went to the holley site, but they did not say anything about what the max input pressure could be. Did not say anything about EFI either. Looks like aeromotive has some good choices on pumps and regulators but they sure are pricey. This is the part #'s I found # 11106 pump, # 13301 regulator. Together they are about $480.00. Here is the link. http://aeromotiveinc.com/products-page/fuel-pumps/. I like the inline pump style but I would like to fine something for less money.

I'm running the A1000 pump, with a return line and the A1000 regulator (13204)

No problems at 7psi!

Whatever you decide you need, let me know. I have a big stock of Holley, Magnafuel, Aeromotive, Fuellab and more.

There are several ways to go about it, if you are using a stock tank, I would use a in line pump, and return it with a T just before the inlet to the pump. Affordable option. Aeromotive has several high pressure low output pieces that will work, they might cost but you get what you pay for.

Thanks for the info mike. Sounds good, I will let you know my shopping list when I decide what pump to go with.I will also need a filter. I think the reg you suggested will work fine.

I think you may be right about the inline pump. I am thinking about scrapping the idea of in tank fuel pump. I think the 13204 reg will work fine. The pump I am looking at is aero #11106. Says it suports 700hp with proper plumbing.

The stock tank on a 67 camaro only has one line in the sender. This happens to be a six cylinder car so the line from the tank is a 5/16. The v8 cars came with a 3/8 line. So here is my solution. I found this searching yesterday. http://www.robbmcperformance.com/pro...78_gmsend.html. Looks like this will solve all my restriction problems. It also adds my return port.


Not sure if I understand about the return just before the pump inlet. What would this do for me.

For roughly the same Tanks inc has a sendeer with built in pump assembly. you could use that and run the rest of the system. Give me a call for any help.
