EFI fuel tank

[horsepowerjunkie]

did any of the FMJ body cars come with a EFI fuel tank that will fit in a Aspen/Volare?

No. Since they never had efi theres no tank you'll need to be creative.

I used the Holley in tank retrofit kit. With our shallow tank, it was tight at the limit of how short you can make it. I used Part# 12-136 it accounts for the lack of tank baffling with a wicking mat that is surprisingly effective at keeping the pump from being starved.

I did have to put a little bump in the spare tire well to make room for it.

So the 88-89 M body cars did not have the TBI 318 engine?

No, they were carbed till the end. Which is a bit odd because trucks got it and those two years got some of the biggest changes in the entire run next to the shift from the 70s to 80s styling.

Interesting! I assumed the cars got the same as the trucks

Ahhh...got it now...at first I couldn't tell if that 1st pic was just a "side by side" compare of the fitting...but the genius in-tank pics shows this very well!

Nice sir...thank you for sharing this.

BTW: given the stamped ribs in tank body, did you have to 'massage' that area for the Holley piece to seal-up? I imagine the answer is a yes, so I'm curious what you found worked best to get that done..after all, hard to talk about flattening these out unless you get something into the tank itself to be the 'anvil' in that situation.

I was able to build a custom in tank fuel pump and sender based on a Holley blog.

I posted pictures of the results in a thread about the overall Magnum engine change project.

Have you thought of cutting an area out for clearance and making a cover for it? One of my cars that's what the factory did. Makes getting to the sender so much easier.
