The stock fuel pump in my 68 bird 400 finally failed after 20+ years earlier this Spring. In shopping for a new one, the main brands available were AC Delco, Airtex, Delphi, and Carter. I chose the Delphi as the reviews seemed a little better. When it arrived, I had some reservations as it was made in China and they didn't even include a gasket. Put it on and ran great until last week when it died and left me stranded. Didn't even last 200 miles. So, this time I ordered the Carter since it was supposedly made in USA. Just received it looks exactly like the same tooling as the Delphi and also says Made in China. I think Airtex is probably the same and I don't see the AC Delco one out there anymore. I am thinking of just sending the Carter back because I can't enjoy my car wondering if/when the pump is going to leave me stranded every time I drive it.

I have this (pics) aftermarket pump I am thinking of seeing if I can find a rebuild kit for but not sure exactly what it is. Can anyone identify this?

Also thinking of just going Robb Mc. In either of these cases, I think I would need to make a custom pump to carb line.

Any suggestions? Is there a stock replacement out there that isn't a pile of junk? Car is stock so hoping to keep it as close as possible. Thanks.

I have a Holley pump. So far so good but it requires a regulator

[steve25]

Looks like one I had which was a Holley, and we are talking 3 decades ago!

PS
Holley still offers this pump and it’s item 12-389-11 and goes for 200 bucks and is stated to not need a regulator.

I would guess that they offer a rebuilding kit if needed.

Thanks. This pump is at least 20 years old. I was trying to ID it by the numbers on the metal tag but no luck yet.

Yeah thinking that, but, was trying to see if it is worthwhile messing with this aftermarket one I have first.

When I had my motor built, I put the BOP Carter style "high volume" pump on it. I replaced it with a RobbMc pump because it couldn't keep up with the new motor. But, for a stock type motor I think it would be fine. Only 50 bucks.

This is what I just did for my buddy’s car he went robb mc but wanted the stock line going to carb. Used a AN fitting with npt 1/2 on other side then a qjet fuel fitting cut and weld and it’s ready to go.

Nice work. So, these types of adapters are not readily available then?

I was messing with that old holley I have and noticed that it does actually have one of those fittings for a flaired line. So, I guess this answers that question.

Not the same on the npt side that’s probably 1/4 or 3/8 at best McRobb is 1/2 npt. I could be wrong but that’s going to be a little harder to find.

I just went through this with a Carter 6907 when I swapped from a Holley to a Qjet. I ordered a factory repro line thinking I would massage the carb inlet end to make up for my additional intake height only to find that the outlet on my pump is. clocked different than the OEM pump. The radius at the elbow on the repro hard line (In-line Tube)was ahead of and tight to my crank pulley so no bueno. Prying it further just jacked up the alignment at the top. I had bend and flare one out of nicop using the OEM as a template with a tighter bend at the fuel pump.

Hey Pat,

I looked up your pump number in my GM parts book and came up with GM 6417212, AC 40607. I looked on eBay but nothing at this time with an AC NOS unit. There was an NOS unit in early June that sold for $230. When I placed that number for a search on eBay, many of the replacement pumps popped up from some of the manufacturers you spoke about. So much of this stuff is made overseas today, it's hard to trust the durability of anything! Good luck!

[Ram Air IV Jack]

Pat,

I checked the for-sale parts group for Firebirds here on PY and last year this member had a number of NOS parts and one listed is your fuel pump. Very expensive of course but you if this 1oldgoat still had that pump, you would get a USA made quality unit...

Good luck!

Thanks for the lead, Jack. I agree with the later post that I would have concerns running an old pump where the diaphragm could already be hardening from age.

Personal choice Pat, but with all the problems reported on these offshore made parts, I would take the chance. I don't think that would be a problem with an NOS part and if it was my car, that is what I would do. BUT the price is really high, like so many NOS parts you find today. It appears people are willing to pay a lot for these pumps because few show up and when they do, are snapped up right away. Your 68 400 Bird, like your TA are so beautiful, I would stick with originality but that is a personal preference on my part. I remember you finding and rebuilding a correct date coded voltage regulator for that car but that is a different issue, and it didn't cost that much! Good luck and let us know!!

I have this Carter 120 gph pump new in a box and its Made in the USA.

And only 120 $ vs 200ish for the Holley and Edelbrock.

Thanks, looks like a good option.
