Do you mind sharing that direction?

I managed to stop the leak with a liberal smearing of RTV. After installing the fix, I think I may just JB weld (or other epoxy) it, since there doesn't appear to be much pressure on it.

I'm not sure what Mike recommends, but of all the fixes I've seen, I really like the kit that Sonnax sells. This thread reminds me that I need to get this taken care of on my truck before it becomes an issue.

That looks like it would work just fine, but for the life of me, I can't find any prices for that kit.

Where would you buy it?

Default My quick fix

So I had the pump rub issue about 1 year ago, I was desperate for a quick fix, so I grabbed the red permatex rtv, I found the small pen hole, made it a little bigger and sqeezed some in their directly from the tube. It has been in a year and no issues yet. I do plan on rebuilding this eventually.

So, that's an 8 year necro-post, but what the heck, I'll join the fun!

Coincidentally about 8 years ago, I had a pump rub pinhole, and slapped some RTV on. Eventually got the pump rub kit, but i never replaced the case half. So that RTV is holding back the leak almost a decade later.

Now I wonder if I should've skimmed the thread, this could be totally off topic. Eh, not like anyone will care after 8 years, I bet.

Edit: oh dang, I was posting how I smeared RTV on 5 posts up! So yeah, follow up: it still doesn't leak

I'll add to this. JB weld for me. Lasted 3 years until the pump started rubbing another hole in a different spot. Then I had it fixed with a newer half.

It is weld able. Ive done my tahoe and my dads 263. Turn the gas up high and it can be done. To grind it clean use a course cutter and go slow. It really isnt hard welds just like aluminum. I would say wile you have it out replace the “wear” parts and clean the pickup tube strainer.

If you have a hole in the housing, you have nasty gouges on the inside. Usually The snap ring groove is wasted. You need a new housing.

My cajones aint big enough to dare even THINK of welding on magnesium. Permatex makes some out of this world strong aluminum epoxy stick, but it said in bold print not to use with any magnesium alloy. I also have duraweld torch filler rods, but the test it gave to see if it had enough aluminum in it to stick and mix in failed. I lucked out and picked up my 261 case out of a wrecked 03 that had almost 300k miles for $650. I got there and the date stamp on it was from 06 so it wasn't the origanal case for the truck. Got it home, pulled it apart, and it looked new inside.
