It appears that the fuel pump on my LT-1 has developed a severe leak. The long trailer ride out to Ohio may have had an effect on it??? Is it possible to have it rebuilt, I would hate to have to replace it, as it's the original. If so, can someone recommend a reliable rebuilder?

If it's the original pump, that means it's about 40 years old. I'm downright amazed it lasted this long. You were driving on a "wing-and-a-prayer". If one of these things fails in your garage, the fuel will siphon right out of your tank and onto the floor of the garage.
Personally, I would never use a rebuilt specimen of one of these crimped type fuel pumps. However, there are folks that rebuild them, sometimes replacing the lower steel shell of the pump (the crimped part). Paul Baker at Goat Hill Classics in Long Beach, CA is one of these but some folks have reported problems when sending him parts for rebuild. I don't know, specifically, of any others.In Appreciation of John Hinckley -
Re: LT-1 Fuel pump rebuild
I think that Paragon "may" be the only source for a replacement with the AC logo cast into it. $50 on their site ($45 with discount).

Re: LT-1 Fuel pump rebuild
Kevin,
The original fuel pump on my 71 LT-1 started leaking right after I bought in 11 years ago. I had the same issue but it can't be rebuilt. Just save it and put it on the coffee table. The Paragon replacement is the only real way you can go. The original in the 70 is still holding up. I'll keep my fingers crossed on that one.Comment

Re: LT-1 Fuel pump rebuild
Hi Kevin,
Just for your info.
At Carlisle I happened to be standing near the Goat Hill booth while one of the persons at the booth was explaining to a prospective cusomer what they do in the rebuild. He said the only part of the original they use is the casting. All else is new, incuding the 'can' as Joe posted.
So it sounds like one from Paragon might not be that far off from a rebuild of your original.

Re: LT-1 Fuel pump rebuild
Hum, way back when, I needed a new pump for my base 350, '71, SB. Yep, Paragon DID have old stock of the AC 40769 pump and what was in the box was a service replacement built BEFORE the guys at AC sourced the production offshore.
The pump number was embossed into the side flange as factory original and the upper casting DID have the raised AC identifier. It was priced in the $50 range.
Then, a few years later, I decided I had better grab a 'spare' and was surprised to see Paragon had executed a 'strategic' pricing move... Instead of the pump being $50 it was $155!!! I bought it anyway knowing these puppy dogs were getting HARD to find.
For grins, I checked my Paragon catalog just now. The good/correct version of the base engine 40769 pump remains listed at $155. The LT1 pump, 40709, is also listed but priced at $155. The BB pump, 40770, is still listed but priced at $175.
Now, the current Paragon catalog also lists 'similar' pumps at less $$$. For instance, they offer a base 40769 pump with number stamped but WITHOUT the raised AC logo at $30. So, this can be an issue of how close to the factory original version of the pump you want to come...
I've seen bona fide AC pumps (at least as far as the retail box goes) that are correct in terms of fit/function, but without the raised AC logo and with their PN silk screened on vs. being stamped.Comment

Re: LT-1 Fuel pump rebuild
Apparently they're now selling 3 versions of the pump. Generic, one with AC logo, and one with AC logo + part number stamped on the flange. The AC logo one is $50 (and it's the one I found originally) but as Jack mentions to have the part numer on it is an extra $105.Vice-Chairman (West), Michigan Chapter NCRS

Re: LT-1 Fuel pump rebuild
Thanks guys for all the great information! While at the Metro Long Island Chapter meet this weekend, I was given a reference by the name of Arthur Gould. I searched his name here on the TDB and several posts revealed that his expertise is mainly working with water pumps. Is anyone familiar with this man, and his abilities to rebuild fuel pumps?
Another member brought along a replacement pump for me, for temporary use while researching!
Thanks again!
Gordon, very nice to see you as well!Comment

Re: LT-1 Fuel pump rebuild
Kevin,
Arthur Gould is a long time fuel and water pump restorer. I believe one of the best. My guess is he will tell you that the "crimped" type pumps cannot be rebuilt as Joe Lucia has stated all along. An earlier post referred to Goat Hill rebuilding these pumps. I'd question how he does it safely.

Re: LT-1 Fuel pump rebuild
Yep, your right again Dave (and Joe/Jack)! With a quick phone call I was just given that exact information. I was told that after the change (screwed vs, crimped) sometime around 67 that the newer style cannot be reliably rebuilt. However, there is a possibility that they might have the correct NOS pump in stock and are checking now.Comment

Re: LT-1 Fuel pump rebuild
No luck on the NOS pump, they were out of them..........guess it's the Paragon replacement as Patrick has suggested.
Thanks again to all!Comment
