Penglii Posted April 14, 2010 Report Posted April 14, 2010 I want to replace all (or at least most) of my vacuum lines, and I understand that silicone vac tubing is an excellent alternative to the OEM crappy rigid plastic lines. Anyone know what the total length of all the vac lines is for a 3100 engine in a 1st gen grand prix? From replacing my vacuum canister line I see that 4mm inner diameter tubing is a good fit... are all of the vac lines that same size? Quote
RobertISaar Posted April 14, 2010 Report Posted April 14, 2010 i don't think there are that many plastic vacuum lines, but i could be wrong... i thought that was much more prevalent on 70s/80s cars... but yes, silicone tubing should last longer, assuming the vacuum won't collapse it. Quote
Penglii Posted April 15, 2010 Author Report Posted April 15, 2010 I don't think there are that many either... but it is hard to estimate their lengths without removing them from the car. Quote
RobertISaar Posted April 15, 2010 Report Posted April 15, 2010 i may not be able to give you an estimate, but this should give you a good idea where to look to measure for yourself. Quote
