where can you get -10AN fittings for 5/8 aluminum fuel line??

in jegs i found 3/8 and 1/2 but not the 5/8!!!

thanks

 

Earls has many of the -10 (5/8) fittings available they just aren't as popular as the 3/8 (-6) and 1/2 (-8) fittings. In most cases you can take the Earls part number and figure out the next size up fitting part number. For example: a -8 tube nut is part number 981808ERL, and the -10 is part number 981810ERL. The tube sleeve(s) that go with the nuts are 981908ERL and 981910ERL. If you have specific fittings you are looking for but can't find them listed in Summit I would suggest going on the Earls website and look at their online catalog. Or just call Summit Tech Service.....

 

I heard that george baxter used -8an line because he thought that the Gs generated when launching would make too much force to the pump on the -10 AN line... his line was enough.. i think

 

I keep reading these posts on here about fuel systems and many people overkill it so much. I have a 1994 Ford Lightning with a single turbo system that pushes well excess of 800 rwhp and use nothing more than a -8 feed line. My Aeromotive pump does sump the tank and I did build a baffled fuel trap box over that sump so that on launches it receives plenty of fuel. But, since 1995 when I built it, I have never had any fuel system problems nor a pump failure.

What I did though, and I have heard of these pumps failing, is use a voltage controller. You also have to understand that the original design for these pumps was for aviation use. In that, most aircraft use a 24 or 28 volt system. By doing this, the pump operates at a much higher efficiency electrically with a lower amp draw. This facilitates two things... it allows the use of smaller, lighter gage wire and also reduces the thermal load on that wire or pump motor. When you use this with 12 volts you also double its amp draw thus increasing the heat it needs to dissipate.

Also overcoming the Ford dual tank system was an interesting challenge. So I switched the factory supply line for a return line. My front tank feeds into the rear tank return line which allows the greater range for driving trips or the use of race gas in one tank for racing.

Here are a few pics of the install.





Here is a pic of the complete setup.


Hope this helps.

 

That is because too many HP shops have old school carburetor training.
They think a system running at 45PSI and a FM FPR has the same problems as a carburetor system running at 5-7PSI.

-8 Teflon line is enough to support 1000HP with a good pump system.
-6 Teflon line is enough to support the return line.
Braided Teflon flows better, lasts longer and is cheaper than braided rubber hose.

Factory lines are good for upwards of 700HP* with a DP pump system (*BSFC, voltage and pressure dependant)
