quote:The pump ships with about 3' of standard 1/4" nylon* icemaker tubing readily available at homecenters. If that's too large to fit your Toyota's dipstick tube, it shouldn't be that big a deal to obtain a 1/4" to 1/8" reducer to use 1/8" nylon tubing for the diptstick opening coupled with just enough of the 1/4" tubing to fit up with the vacuum pump. Or you could buy a new ride... If you catch a used oil sample midstream from the pan drain into a clean, dry container, I don't believe you'll run afoul of an accurate analysis. *I suspect Blackstone sourced nylon because of its heat resistance. Think twice before you substitute vinyl tubing.
