MSD ATOMIC EFI conversion kit

[LA75]

Does anyone have any experience installing one of these on their EB? If so, did you install the 23 gal tank or did you set up a transfer system from the aux tank to the main? I am considering putting one in, but not sure which way to go.

PS: I live in Louisiana, very hot in the summer, so I will need to set it up with a return system.

I used the 23 gallon tank. You can add return line that installs in the fuel hose to your rear tank. Moroso part 65385 Efi return line installation kit. I have new that I'll never use. If you want it let me know.

Thanks John. Did you remove the aux tank or just cap it off? I am assuming I can use my low pressure lines for the return? They are brand new. I just replaced the entire fuel plumbing.

Did you install the MSD KIT?

I bought the whole msd kit. I probably could have just used the basic kit but since I found the whole kit for the price of a basic, I bought the whole thing. I removed the aux. tank mainly because I didn't need 33 gallons and I never cared for the tank on the outside of the frame rail, right under the drivers seat. I'm not 100% sure about a return line but you're not supposed to use hard lines when plumbing the MSD.

I did read not to use hard lines. Just reading the MSD instructions online, they said if temps are greater then 81 degrees to install a return. How do you like the set up?I will probably go with the 23. Seems like it would just simplify the whole process. I'll let you know on the return kit. The tank I was looking at has return fittings plumbed into it. I'll message you if I have any trouble if that's ok?
Thx.

I run the return line and it just goes to the filler neck, no issues. Get the system running without the timing control (to make sure everything works) and then convert it to timing control. It makes all the difference.

I just finished installing Holleys Terminator EFI, I installed http://www.jegs.com/i/AEM/017/50-12...a7xpfVOd3dWUsFAxIjvBrz2FMmzHki2eNGxoCdvLw_wcB

with the stainless braided line and fittings(not pushloc) my fuel system cost me less than 450 bucks, I looked at the ones offered by MSD, and you would spend over 600 bucks for lower quality parts....(and an externally mounted fuel pump...)
