help me decide what route to take with my fuel system

my fuel pump on the 1970 duster crapped out on me. Ive had it since i built the car in 06, so it doesn't owe me anything. especially since it was the summit special.

that leaves me open to some debate, though. what would you do:

the car is a mild 360. 750 edelbrock, 400HP at the wheels. primarily a cruiser, but i enjoy running it hard and plan to make some auto-crosses next year.

current fuel system: stock 5/16 line and pickup, dead summit mechanical pump.

never really had any noticeable fuel starvation problems until the pump started going to hell.


1. replace with another mechanical fuel pump. I'm thinking another summit. they're cheap and fairly reliable.

2. upgrade to a carter high volume pump and a regulator.

3. (this one would be the most expensive, and the most difficult) upgrade to 3/8 stainless pickup and lines. holly blue pump and regulator.

the car is already wired for an electric pump, but after plumbing a fuel system on a 440 six pack new yorker today, using hand bent 3/8 stainless lines, and a Holley blue and regulator, I'm not sure i want to go this route. if i do, id buy the pre-bent stuff from classic tube. but where would i place the pump? I'm not seeing a whole lot of extra room under there for a pump the size of a Holley blue, but cant find a lower profile, reasonably priced pump and regulator combo.

anyway, what would you recommend? am i missing an option?

goal is dependable, quiet, sufficient, and budget friendly fuel system. id like to keep the whole deal under or around $250. also has to be a very neat, and clean way of doing it. the whole car has a very stock vibe, but that's slowly morphing to more of a vintage style PT var.

"goal is dependable, quiet, sufficient, and budget friendly fuel system"

Quiet and Holley Blue are mutually exclusive to one another. If the above quote is what you really want, replace what just died with another just like it.

If I were you, I'd go with a Carter Street/Strip pump, mounted back near the tank. They are much quieter than a Holley pump, and from what I've seen, are MUCH more dependable. Even the way they mount the pump is designed to be quieter, in fact, when I DO mount a Holley Red or Blue pump, I replicate their mounting system.

Sometimes it is best to go with it ain't broke don't fix it scheme and if the old one was working until it failed just replace it perhaps with a high volume pump and regulator..just because it is different does not always mean better...

I have tried most all of it and now do what is known to work..
