I just acquired a very rough 7017375 unit. I seem to remember John D saying an undisturbed pump had seals in the bolt heads (see attached). Is that what this is? Also the adapter plate has an "OK" in marker on it (see photo). Did the factory do anything like this? Thanks, Don H.

Yes Don, that is an undisturbed pump with the lead seals filling the head of the screw.It's a good life!

Re: 63 F.I. parts
Hi Don, You are very lucky to have a high pressure pump that is untouched. So many of the FI pumps are really butchered up. You haven't lived until you try and get a pump seal out that is heavily expoxied in the bore. Very nice pump you have. The "seals" is actually lead in two of the allen head bolts that has initials in it from the AC line. The Fuel Injection hi-pressure pumps were not made by Rochester Products. AC made them.
Your 63 pump should be 5630006. Made In USA and AC above that info.
Color should end up blackened although a minority of the pumps had a rosette color to them. I always thought the service replacement pumps from GM were this color (reddish-burgundy) but I really don't know for sure. John
Hopefully the OK is not etched into the casting.Comment

Re: 63 F.I. parts
John,
Are the plugs typical for all the fuel pumps? Do the wobble pumps have them as well? If a pump still has the plugs, what should one do if the pump moves freely?
Should it be left alone, or is it still best to go through and check it out? Are most pumps taken apart because they are frozen up?
Basically, if you are lucky enough to find a pump like this and it is free moving, what do you recommend doing to it?

Re: 63 F.I. parts
The pump turns free and the gears look good - what I can see through the hole. But I will definitely put in a new seal which requires disassembling it. Thanks for the replies. Don H.Comment

Re: 63 F.I. parts
Monte, Wobble pumps are held together with 6-32 screws so the answer then is no on the lead "plugs'.
On a typical 57 to 65 pump that has been tampered with since day 1 you would be very lucky to be running it without a fuel leak.
My 63 the LWC has a NOS hi-pressure pump on it. But I still put a new viton pump seal in it so I wouldn't have issues with leaks. You have to really watch these pumps as if they start leaking you can easily have a big time fire. JohnComment

Re: 63 F.I. parts
My car experienced that exact thing. The hood and the passenger fenderwell and a small section of the fender were burned. That is why the person I bought the car from took off the F I unit. I got the car with a carb on it. Sometime in the 70's, the car caught fire and from then on he ran a carb. I was very lucky he did not get rid of the f I unit, but he did loose the air cleaner over the years.
They had hacked the fender back together. Other than that the only other thing that was missing was the original overflow tank bracket. The fiberglass one. Now, you have to remember I did most of the work on this car before the started reproducing anything for a 63.
That fiberglass bracket and the emergency brake parts under the car were the hardest thing to find back then.
Now, you just order them. I am not sure which way I like it better. It sure is easy to build a car now compared to the old days.
Thanks for the response. Itis very important for poeple to know it really does happen.Comment

Re: 63 F.I. parts
John DG,
Can the pump be gently disassembled without messing up the lead plugs?

Re: 63 F.I. parts
Can somebody tell me how tight those bolts with the lead in them typically are. The reason I ask is there is a set of tools made for building the injectors on big trucks. They are made to take the actual injector apart.
Anyway, they make a 1/4" X 32 socket and many other small sockets with a lot of points. It is like a very fine spline. Many many splines with a tiny bit of bite each.
I do not remember who made them. I has been at least thirty years since I built an injector for a big Detroit Diesel engine. I have a friend who has a Snap-On truck. I will check with him.
Somebody out there makes a tool that would come very close to fitting that allen if not a correct fit.
Again, typically, how snug are those to remove or retighten?Comment
