Accelerator return spring questions
I need a good correct accelerator return spring for my 54 with a 239 Yblock. I've been using a hardware store spring. It looks a lot different and not as beefy as the one in my 55 239. It does not return my truck to idle quickly enough recently. I checked Dennis carpenter on line and Midfifty's catalog but no luck. (Edit: I just checked Midwest Early Ford. No luck there.)
I found these NOS springs on eBay. Part #7HC-9737 ad says it's for 48-53: https://www.ebay.com/itm/1948-49-195...8AAOSwo8hfF33k
Part #: TAAA-7523-A. https://www.ebay.com/itm/1953-56-For...IAAOSwlxRfR-hQ. This I think is for a 6 cylinder
Would a clutch or brake pedal return spring work?

A brake or clutch return spring is infinitely heavier than a throttle return spring. You'd break something if you tried to use that. A spring too stiff is hard on throttle shaft bushings. Plus, it's over 13" long. You need TAAE-9737-A 54-55* F-100-600 with 239 without Fordomatic, 4.05" long, 34 coils, .88" diameter.
*It may fit more years, but that's as far as my catalog covers.

That's basically what I was going to say. They are way to heavy.

A google search of the TAAE part number found this old thread.

And here's listings for the replacement spring ND mentioned there.

I have heard of throttle springs breaking with bad results. Apparently the recommended fix for that is a smaller spring inside the bigger one. A double spring.

Would something like this work for your set up?

I've had a throttle stick once when I was 16. Whoa Nellie! Make ya pucker and pray!
I have roadside cross a mile from my house - a direct result of a hot rodder in his roadster who ditched it at WOT. 60 mph multiple rollover - final crash investigation ruled cause as failed throttle return.
Belts and suspenders man - buy a doubled return spring!

For a universal spring setup I've had good success with these universal springs from Holley. Good and not too much pedal pressure. They are a stainless steel (not chrome) double inner and outer spring setup and about 4.5" long end to end. Holley 20-89 Holley Chrome Throttle Return Springs | Summit Racing
Not original, but seem to work just fine.

Brian, thanks for bumping this thread to the top.
As I said in the thread about my first drive of the season. I bought a NOS accelerator return spring. It looked too short but I stretched it to fit. I have to push the pedal harder than I was used to. But it returns to idle faster.
