Aeromitive 10AN fuel pump, what lines?
Well the body is off and the frame is getting prepped! I have my 10AN in-out electric fuel pump, and am ready to order the fuel lines. Are stainless steel big block lines enough to feed my 365hp FI small block? I was alternatively thinking a braided line from the pump up to the motor, and a regular SS line for the return line.
The easiest would be the stock SS lines, but since I'm doing this right the first time, I want to be sure I'm set up properly before the body goes back on.
Thanks in advance for the input.

I actually bought the pump used, it's a paxton but supposedly made by aeromotive- the in and outlests are made for 10AN fittings, and am sure I could adapt the pump end to any line running up the car, but not positive.

Aeroquip, among others, makes hardline to AN adapter fittings. With only 365 hp, -10 is way overkill, but it won't hurt anything. -06 would work, and it's roughly equivalent to 3/8" tubing, which is common and bendable with a hand bending tool. -08 is closer to 1/2" is about the limit for hand bending, and you'd ahve to get the tool from an industrial supply house. Otherwise braided ss hose is the easiest to run, but you should check them every couple of years as they deteriorate from the inside out, even the one's rated for fuel use.

thaks for the input so far all. I was thinking of ordering replacement SS lines forthe car, the pre-bent type. I figured the big block lines would flow enough fuel. If so the Aeromotive adapters will work I assume?
Also, if I run braided up to the motor, how do folks run it past the tranny crossmember? I don't think they would fit through the x-member, so under it would be the alternative?
Thanks and keep the input coming...

I ran them over the tranny crossmember, -10 to the engine and -08 return both covered with Firesleeve, so smaller should work as well.
The big block lines would be more than sufficient and will be very clean looking.

thanks Monty. So it looks like big block lines to and from the motor and aeromotive adaptors to connect the line to the pump. I've decided to use a stock pump with a sump welded in, and an aeromotive 10AN filter, installed in the back just before the pump... When I get the updated pics on my yahoo and cardomain page I'll post the link.
It's completely apart now, it can only go together at this point hehe.

Keep in mind that 2 fuel filters are recommended, a 100 micron before the pump, and a 10 micron after. Aeromotive sells both elements for the filter housings. It's probably overkill, but the 100 micron filter element reduces the effective head/restriction the pump has to pull against(electric fuel pumps experience reduced efficiency and durability when they have to pull a large head or have to pull against a restriction), while the 10 micron provides the filtration needed for your fuel injectors. Something to think about...their fuel pump controllers are nice to have too, but it does add to the cost of your project.

FYI - The reason I mentioned looking at the instructions is that many of the newer pumps that are not submerged in the gas tank are liquid cooled by the gasoline itself (Aeromotives are good examples). They require a minimum flow rate and recirculating setups to keep the pump cool. While -10 may be overkill for the engine HP, it might be needed to keep the pump cool, especially on hot days.

According to Aeromotive on the A1000 pump they want you to use a -10 fitting -10 line coming out of the tank/sump to the first filter and then -10 line into the input of pump. From the pump to the second filter and onto the regulator they want to see -8 lines.

Thanks James. Is a stock big block fuel line -8AN? If not I'll need to run braided lines. also will I need -8AN for the return line as well?

I do believe the stock fuel line is 3/8 inch OD. In order to not cause pressure on the return side the return line should always be the same size as the feed line or larger. Again this is what the manufacturer states. Others might be proving this wrong.

Thanks all for the input. I ordered a fuel sump, 3" of -10AN line for the tank to the 10 micron filter and pump. I also got the 100 micron filter, and 2 15' -8AN stainless braided lines for the run to and from the motor.
I guess if I add a supercharger I have the fuel delivery covered!

Well I'm installing the fuel system, and have just 2 questions:
Has anyone run -8AN braided lines following the factory path of the original lines without any clearance issues?
Can the 100 micron post-pump filter be up in the engine compartment or does it need to be directly after the pump?

The 100 micron filter is PRE fuel pump...the 10 micron is the POST pump filter. You can mount the post pump filter where ever you like.
Good luck,
Jeff

Will this be ok or will the top line cause clearance issues?
