I'm looking at what needs to be done to install my 345hp crate motor into my 67 mustang. Is the stock system enought to support that hp level?
Im running a holley mechanical pump, stock lines and pickup.

Thanks

No, the tank pickup will likely be too small. Most of those neck down below 5/16".

Check to see if your sender has 3/8" tubing or not. I think the
change from 5/16" was made in '68 though. Tubing from front
to rear I believe was 5/16-inch as well, but you may have already
got that fixed by now......

Yep, you should upgrade your lines.

Most aftermarket fuel sender pickups are made with 3/8" tubing, at least that is the case with the 65/66's. The tubing under the car can also be upgraded to 3/8" with aftemarket sources. Best to specify the 68' style under car tubing as it has better bends and is not located next to the driveshaft (which could be a safety issue.)

350 is the limit with 5/16" lines. As others have said a 3/8" upgrade is easy. Most companies sell a new drop in fuel tank pickup in 3/8", and you could route 3/8" line.

Just a thought but Mustangs Plus (name for now) sells a EFI fuel sender with a 3/8" outlet and return. The return can be capped and clamped for a future EFI upgrade.

I got an aftermarket replacement tank for my 66, and it was set up with 3/8 inside and out.
