Hello! New to this forum as well as a new Samurai owner. Picked up an ‘88 recently. I live in the Phoenix, AZ area where emissions testing is required... took it in and it failed for a few reasons. Biggest one is, according to them, a “missing purge line”. Biggest issue for me is I know next to nothing about working on vehicles so I’m trying to learn this stuff 

The most I know about this is that it appears I have an aftermarket Weber carburetor and I am assuming that is where the problem lies - that maybe this carb does not use the line that they say is missing? Maybe I’m not on the right track there?

Interestingly there IS a hose that is plugged with a bolt. Also there is a capped elbow coming off of the carb and there are several places that appear a hose could go to but they are also capped. Any help would be GREATLY appreciated!

Been trying to post this with pictures but I can't get it to work 

Okay here is a link to the pictures...

You're in a very challenging situation, you're in a state which requires emission testing, with a vehicle that has had it's emission equipment removed by a previous owner, and to complicate it, you're not familiar with emissions control systems.

The purge line being referred to is most likely what is known as the EVAP purge line - the Evaporative Emission System purge line - this is a system designed to trap gasoline fumes that evaporate in the tank and store them to be burned in the engine rather than vent them to the atmosphere - it's a fairly complex system of pipes & hoses that connect to a fuel tank vent at one end, a storage canister (typically mounted under the hood), purge valves that control flow, etc..

Your challenge is going to be figuring out how much of this has been removed and needs to be sourced & refitted - I doubt that this is a simple as connecting a tube between point a & point b

To make a long story short - on a vehicle of that age, I don't think you'll be able to do it, short of finding another vehicle which still has everything to scavenge it from - so you need to look for a way around the need for emissions testing, either using the vehicle as "off road only" if that is permissible in your neck of the woods, classic/antique registration, again subject to local law.

Thank you for the advice! I don't know if you looked at the pics at the link I posted, but, do you think that taking it to a mechanic as it is to make it emissions ready could be expensive?

Read my previous post again - and please note that I am not familiar with emissions test requirements where you are.

Based on your post there were several reasons why it failed testing - the biggest being a missing purge line - they know it's missing a purge line because they can see it's not physically there.  You're thinking reconnect the purge line and re-test - I'm saying it's not going to be that simple - the purge line goes to a BVSV (bi-metallic vacuum switching valve) - is that still there or is it missing too.

From the pictures I can see the EGR (Exhaust Gas Recirculation) system has been disabled (vacuum lines have been removed & ports capped), did the testers draw that to your attention, did they get that far into the tests?  The hose with the bolt is a part of the PCV (Positive Crankcase Ventilation) system so that's been tampered with also.

My suspicion is that you will not be able to make it pass emissions testing without replacing all the missing bits, and quite possibly refitting the original Hitachi carb and ECM (Electronic Control Module) - the challenge is going to be identifying what's missing and locating replacements.

Okay got it thank you VERY much!
