Looks good, thats where my pump is mounted. At one time, I added a wimpy carter 72GPM (p/n 4389) pump and filter to my stock system and it made no difference at the strip, it might have actually made things worse.. The only thing it was good for is when the car sat for a while, it would fill up the carb so I didnt have to crank on it for so long. After making that change , I ran earls super stock an-8 line the whole way to the carb with a return reg and 1/2" tank pickup and 3/8" return with a mallory 140 pump and canister filter. Same problem again although it only happens when I have less than 1/2 tank of gas. I'm now pulling the tank to sump within the next few weeks which will put the nail in the coffin for good. Ask Cliff for some advice on this, he will tell you the same story.... He went through the exact same pain. Of course, there are guys out there running as fast as 12's with 3/8" fuel line and stock pump but that does not mean that it will work in every application. For every 1 that works, there are 10 that dont... It sure didnt work in my '68... I hope that your story is different but I'm doubting it. There are tons of posts in the archives about this. Where's the pressure regulator? That qjet isnt gonna be happy with more than about 3-4psi. That carter is probably gonna bump your fuel pressure up around 6-8 psi or so...I run mine at 3.5....Good luck, this will likely not be a fun battle! Personally, I think a robbmc 550 mech pump may do more good than the elec pump setup...
My '64 tempest has an all stock fuel system with AC pump and a healthy 400 4spd. Its not as strong as the 455 in my '68, but I havent had a hint of a fuel starvation problem in it yet... Go figure.
