tdtony Posted July 29 Share Posted July 29 I was thinking about adding cruise control to my truck, and I was told the vacuum reservoir are pretty hard to find any more. Does anyone have pictures of the stock reservoir, or any specs about them? I was wondering if I could substitute a generic reservoir. I also found these reservoirs from crown that look similar, but I have no idea how many ports they have, or what the internals are like. https://www.amazon.com/Crown-Auto-52004366-1991-1996-Reservoir/dp/B00A4HXJJS?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=ATVPDKIKX0DER Link to comment Share on other sites More sharing options...
eaglescout526 Posted July 29 Share Posted July 29 Don’t get the crown ones. They’re for the HO and only have one port on them. The Renix 4 ports look exactly like that football but with 4 ports. As far as specs, I think most on the market will hold the same vacuum pressure that the engine will produce. Shouldn’t need anything incredibly strong for cruise control. The GM tin can ones can work as a substitute or any two port ball really. Link to comment Share on other sites More sharing options...
tdtony Posted July 29 Author Share Posted July 29 Just found this on eBay, what's a reasonable price for one of these? https://www.ebay.com/itm/256465605352?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&mkscid=101&itemid=256465605352&targetid=2512152189032&device=m&mktype=pla&googleloc=9197851&poi=&campaignid=21214286338&mkgroupid=161030074701&rlsatarget=pla-2512152189032&abcId=9407521&merchantid=653412184&gad_source=1&gclid=Cj0KCQjw-5y1BhC-ARIsAAM_oKl2dl5KdfWKY3ywmvSO7LaRS_i-cVgArvR74Y6KyNo0ktEmfpxjvx4aArbfEALw_wcB Link to comment Share on other sites More sharing options...
Tex06 Posted July 29 Share Posted July 29 I pulled 3 or 4 from a junkyard for $1-2 each and used what fit best. I believe I ended up with a 2 port GM ball that I mounted in the front by my battery. Link to comment Share on other sites More sharing options...

That’s outrageous honestly. $70 for a reservoir that yes you can’t find much anymore but is only for a small niche of XJ and MJs. $30 and free shipping would be the most I’d ever do and go to get one if I needed one. As said above, junk yard is not a half bad idea to search the older stuff and see what you can find. Link to comment Share on other sites More sharing options...
tdtony Posted July 29 Author Share Posted July 29 Yeah, I'm gonna head to a junk yard tomorrow, but I don't have high hopes Link to comment Share on other sites More sharing options...
