So it looks like somebody messed with the vent lines and did a pigtail with them can anybody send me a photo on how it’s supposed to be routed. They even capped off one of the vents. Thank you for all the help. wpz455@yahoo.com
THe two vent hoses are supposed to come up above the clip that's holding your single-looped hose in place. The hose on the left, as I recall, is slightly larger than the hose on the right. As well, the hose on the left is supposed to have something called a restrictor (looks like a piece of spongy material to me) plugged into the hose. I never liked that set-up so, instead of trying to find something to simulate a "restrictor", I went with the set-up used on the '69 models, which Fusick reproduces. I have an old Fusick catalog and their part number for it was GTF690K, gas tank vent tube filter kit. You can look it up in Fusick's on-line catalog at www.fusickautomotiveproducts.com. It just seems to be a more sensible set-up than the one used for the '68 model year.
I'm not sure what Randy is talking about ,but every 68 I have had [ many ] has had the gas tank filter vent. all Lansing built cars except for 1 Canadian built and it had it also.
What I am saying is shown in the lower right side of the '68 A-Body Olds PIM, manual section 8, page 111, which shows the dual vent tube set-up for the gas tank. Randy C. PS: That filter set-up was amended with the '69 model year to show the filter set-up that Fusick offers as a reproduction.

Reason: add more info
I have found the assembly manual is not always accurate as to what was actually installed on the assembly line. it may be by the time my cars were built they were installing these surge valves /filter vents on 68 model cars ,I have a hard time believing someone added them to every 68 car I owned. another discrepancy is the assembly manual says notched valve covers were installed on both heads as Joe conveyed in a recent thread about valve covers, but my 68 W-30 only has one notched valve cover and it's on the passenger side ,since it has factory manual brakes it didn't get one on the left side ,there is no evidence it was changed or a repainted valve cover from a 67 [flat top] it's unmolested,not taken apart. just saying the assembly manual was printed before the cars were actually built and things changed during production ,also things were not done the same from plant to plant. I have known and still do know several guys that worked on the line when these cars were being built ,including a couple of CO members and a friend that I recently worked on his 71 W-30 ,he is getting old and had a stroke and couldn't do the work himself . he has told me many tales of what went on during assembly. food for thought.
My '68 4-4-2, a Lansing car built in the first week of April 1968, came with the vent hoses and restrictor per the assembly manual. My '69 4-4-2, a Fremont car with a build date of the third week of May 1969, came with the new vent hose/restrictor assembly shown in manual section 8 page 111 of the '69 PIM. That's also the same assembly the Fusick has in reproduction. The '68 set-up seemed real basic to me, whereas the new '69 set-up seemed a bit more refined. That's why I removed my old '68 set-up on the '68 and installed the repro '69 set-up. It's not an original set-up, but no one looks there!
A little more info I learned about the Lansing assembly plant is that I talked with the dealership owner a few years ago that sold my '68 to my parents. He loved it when he got cars from Lansing. Conversely, he hated it when he got cars from Fremont. He said the work ethic at Lansing was top notch, that you could practically eat off of the floor there. He said Fremont was another story. I can believe it by what I saw in restoring the two cars. The '68 was perfect in almost every sense - nothing missing, good fits on doors and the hood, and so forth. The '69 was missing a lot of fasteners - screws not there, wiring not where the assembly manual said it would be, rubber grommets missing, and so forth. My '69 has factory cruise control so the speedo cable routing is different than a car without cruise. A rubber grommet should have benn placed in the opening where the cable would go on a car without cruise but mine wasn't there - it was wide open to the weather - and it most likely explains the rust holes in the forward part of my driver side flooring.
Regardless, these cars are fun to have and nice to work on!
I have to agree they are fun to have and the Lansing cars are nice to work on except maybe the 70 W30 A/C car I am working on ,not so nice ,
I am not a fan of the A/C cars. my 68 W30 4 speed was built the 5th week of April 68 with few options ,no power anything , no radio = no antenna,no speaker , but had drivers remote mirror , simulated wood wheel ,rallye tach and gauges,console ,hood and trunk lights,vacuum trunk release,map light,W36 fender stripe,black interior and vinyl top and not much else. my November Lansing built 68 442 4 speed [ project car]was stripped when I got it [was an all out race car] so I have no idea what it came with but it will have ,remote mirror ,simulated wood wheel, tilt column,console, rear defrost ,the vacuum trunk release from the W30, tach and gauges ,black interior and vinyl top ,map light ,hood and trunk lights,power steering ,radio and a 68 455 H/O engine!
