Fuel tank question (EFI)
Anyone here running EFI? If so what are you doing about the fuel tank? I've noticed all the aftermarket tanks seem to have the pump/lines coming out of the top. Do our cars have enough clearance between the tank and trunk pan for this to clear? I've searched all over the net, but most people have earlier Mustangs with the drop in tanks. I'm about to pull the trigger on EFI and this is the only issue that I'm concerned about.

Thanks in advance!

Autoedit a user here posted a vid here awhile back!


Awesome! Thank you very much!!
I didn't use an in tank pump, the only requirement is to get the external pump as close to the fuel level sender and as low as possible. Haven't had any issues setting it up this way.

Wow, this is good to see. Just think, a few years ago, this was not available! Thank You for the update.

I'm going with Edelbrock E-Street, and using a 'returnless' system. There's an inline lift pump on the frame rail inside of the wheelwell (that's where I put mine), and a high pressure fuel pump in the EFI Sump kit - allowing for a returnless system.


If you want an in-tank fuel pump, they recommend using this Aeromotive in-tank system:

Hope this helps!

Great video! Thanks!!
There's many ways to achieve this, the simplest being an external high pressure pump, such as a Walbro GSLxxx model with a pre-filter and post-filter feeding a regulator up front. A return line will need to be added, for which you can modify the stock sending unit and add a 3/8" port by hand, either by brazing, or some other creative form. If you're very creative you can fabricate a new one.

Contrary to popular belief, an external high pressure pump as suggested above works remarkably well and reliably. In my own case, I welded a sump to my stock tank and added AN ports for feed and return. A better solution would be to simply purchase a high performance tank from Glenn's Performance: http://www.glennsperformance.com/index.php?cPath=78

I was likely going to be using one of these systems on one of my other vehicles in the future. Simple and easy. Similar to the Edelbrock setup but much cheaper.

Wimbledon White 1966 F-100 Shortbed Styleside, 390ci, Tremec 3550, FiTech EFI
I'm also going with FiTech and their external fuel pump kit. The money I save by going that route will allow me to buy a Glenns Performance fuel tank.
