Holley 660's on a Tunnel Ram...What kit for a rebuild?

The carbs I have seem to work really well so far but are leaking at a few different areas...

I'd just as soon rebuild them with new kits but in researching it I'm not sure what I need to purchase...

These carbs have the metering blocks installed in the secondary's and the longer fuel feed tubes...

Anyone have any rebuild kit numbers I can use to get everything I need?

The choke horns have been removed so no carb numbers are there...

In searching Holley's website it seems the original part number was 0-4224 but I haven't been able to find any rebuild kits for this part number...

For the most expensive thing possible, scroll down and click on "service parts":

The generic AED kits have always worked great for me. Always extra parts included which I appreciate.
They may lack the seals for the fuel transfer tube but the rest should be included.

Your first link is what I was looking at...

Times that by two and I was sick...

The second link says it covers the added 4150 style bowl and metering block too...

That may be just the ticket I'm looking for...

After the av-gas stained my intake blue I'm not wanting anymore !@#$% leaks...

Thx a bunch...

the problem is you need a 4150 double pumper kit (with 50cc pump diaphram) like a 3-202qft but it will be missing the transfer tube o-rings those come with a 4160 kit. the 4160 kits come with a 30cc pump diaphram, you'll need a 50 cc.

I'm fortunate that a few years back I bought a accelerator pump tuning kit...

It has a lot of 50cc and 30cc gaskets in it...

When I bolted these on I couldn't get any fuel at the squirter and thought maybe the pump was bad...

Come to find out both 50cc pump gaskets were hard...

After pushing them they dripped fuel on the outside rather than through the squirter...

I just need to make sure I get everything ordered correctly rather than get 1/2 way through and then have to order something else...

Thx...

I'll second Allstate Carbs (allcarbs.com) - always been happy with them.
Transfer tube O-rings should be available in a separate package; handy to have.

Transfer tubes use standard o-rings ... probably less than a dime apiece at your local hardware store.


Way back when - circa 1974 - I was having leaking issues from those o-rings and went through hell to find carb kits with them - only to realize a lot later that I could buy them for peanuts in virtually any hardware store.

Zippy...

I got both kits today in the mail...

Looks like everything I need is there...

Good news
