I have just receive a 61 unit for my 61, there is a 62 unit on car now.
In with the spill valve, spring, screen stuff there is this snap ring, red arrow and a brass cap that was taped on the bottom of the spill valve, yellow arrow. What are these? I am missing the flat metal band that goes between the spill valve and the screen.
Thanks,
Joe
The snap ring secures a screen over the fuel meter vent hole. The brass cap is an anti-splash cap which goes in the fuel bowl at the top of the spill valve.
Don't even try repairing the the axle/link assembly. By a reproduction and you'll never ever think about it again. The repros are orders of magnitude better than any GM original.
The broken ratio roller is also available as a reproduction.
If your fuel meter has the conical spring (like the one in your picture) under the filter and spill valve you don't need anything else to support them.
I'm guessing all these parts were removed (with good reason) from the 7320 unit you just obtained?

Jim,
Thanks for the information. I purchased the car in 2008 and I just received the parts I was promised this week. The PO diassembled the unit in 1982 and put all the parts in boxes. I am thinking he couldn't get the nut off and broke the wire link.
When I did my 62 unit, that has been on the car since 09 and runs great, there was a metal strap and it didn't have the brass cap. Should I put the cap on top of the spill valve? Do you have a picture of how it installed?
Thanks again,
Joe

10 years you, been waiting, Joe?? You have more patience than I have!
Picture of the splash cap appears below. Are you saying your '62 unit doesn't have one? I've never tried operating a unit without one, but I'd imagine that fuel slosh might cause sporadic interference with the delicate balance of the axle/link.
I've also included a picture of the modern repro axle/link. It is incredibly well made. You'll never break it. You'll never wear it out.
EVERY word and pictures posted by Jim are excellent information. I buy/use those links and ratio rollers with ZERO issues, in customers FI units (oh ya, I have 'um in mine also).
By the way, that spill valve splash cone should have NEVER come out. When you re-install it, be sure it is THOROUGHLY secured in its recessed area. It may require 2-3 small stakes around it to assure it stays in place.
Thanks for the information.
I looked back at old pics and I see the cone, I didn't remember it because it blended in with the body and it doesn't look brass.
Also he removed the small pivot pin, yellow arrow, how is this held in?
I also asked about the flat metal spring steel that is up against the spill valve in my 62 unit. Should I have one in the 61?
I know I waited 10 years but I have known the guy for over 35 years and his son is my god son so I knew he wasn't going anywhere. The unit on the car now is operating flawless so i was not in a rush to change it. The deal was when I purchased the car from him I would get all the parts and the FI unit that he had.

When that pin/shaft is installed into the fuel meter and through the axle link, a lead ball is used to fill the hole at the end of the pin. Use a flat nose punch that is a little smaller than the hole and tap it firmly with a hammer. This deforms the lead ball, drives it into the hole and seals it. That's all there is to it. I can't remember if the lead ball is about the size of #6 or #7 buckshot.

Joe,
The cone-shaped spring is the filter support for your FI unit. It completely eliminates the need for that curved piece of spring steel on the spill valve.
The filter under the spill valve and its means of support was one of the many things which evolved as RP gained manufacturing experience.
And the good news is that nearly every piece part improvement was backwards compatible with all earlier units except those with sand-cast fuel meters (mostly '57, but some '59 models also).
