Astro hydroboost return line fitting size?

[casadejohnson]

I know this is here but after sorting through endless threads I can't find it. My return line from the H-boost to the reservoir was leaking a little so I was tightening up the fitting and it broke. I had cobbled together a 90 degree turn at the hydroboost to clear my valve cover and I cant find a replacement fitting for the one I broke. The fitting is smaller than 1/8" and that's the smallest I'm finding. I'm considering just taping for the 1/4" but want to see if anyone knows the correct size first. I wish I could remember where I got the fitting I used the first time.

As mine is a 3/16 size but it is a Gen 1 hydroboost. A gen 2 hydroboost (astro) would have a metric fitting. Ask Madgyver, he is my source for hboost from the Astro van. If anyone knows it is him or Todd Zuecher .

I figured it would be metric but I had hoped somebody knew the size off hand. The good news is that I keep all of the odds and ends from most of my Bronco projects. I did a little digging through my parts bins and by some stroke of luck, I found the original nipple fitting that was on the Hydroboost. It might not be ideal but I can make it work until I can find the fitting I need.

The fitting size is 5/16-24. You can see more details about it in this link (at the bottom):

Thanks, I found that one but it calls for a 3/8" fitting and mine was smaller than that. Maybe there is more than one version of the Astro Hydroboost or perhaps they choose to tap it out to to 3/8".

Todd, Thanks for the link and the information. I'll get some fittings on order.
