View Full Version : Small Diameter Vacuum Tubes

There are two small diameter vaccum connections on my carb and the hose diameter is just a bit too large resulting in a leak. As a result, my vacuum (at idle) is fluctuating between 10-13. I picked up the smallest diameter hose that NAPA had, but it is still just a bit to large to have a snug fit. I also picked up the smallest clamp and it is too large to snug things up nice and round.

The other end of these hoses hook up to the distributor diaphram and choke breaker diaphram and on these ends the hose is nice and snug. Researching on MUD, it seems I need 3mm or 3.5mm (opinions seem to differ) hose. Do any of you have a recommendation for a source? Alternatively, I could also use smaller clamps and good lead on a source for them.

In a pinch, it looks like I could sleave (http://forum.ih8mud.com/40-55-series-tech/58533-mounting-carb-vac-line-locations.html) using heat shrink, but I would like to avoid going that route.

Thanks UB. I just got off the phone with Derrick at Stevenson. It is sold in 3' lengths and two of them are about $9.00. A bit expensive for hose, but definately what is needed.

The Toyota vacuum tubes are expensive but great quality and they fit and last.

Just be glad you're not replacing them on a 60 series. :eek: There's about 50 feet worth.
