Captain, biodiesel is adversely affecting the anti-vacuum exclusion devices! Thank you, Lt.Warf, purge the tanks and carry on! --R Zeitgeist wrote: They had swelled up rather nicely, allowing vacuum to leak out into the anti-vacuum.

Follow-up: Thanks to all who responded, and those who didn't should feel deeply ashamed. I pulled up all the floor mats and dug around in the trunk during my investigation. I believe I found the culprit; biodiesel. Biodiesel has a deleterious effect upon rubber, and it had made a goopy-sticky-globular mess of the gasket ringing the fuel neck. This in turn, allowed spilled fuel to find its way into the trunk, whereby it flowed onto the vacuum lines leading to the fuel flap lock actuator. They had swelled up rather nicely, allowing vacuum to leak out into the anti-vacuum. I simply removed the superfluous actuator and its attendant Y-connectors. I doubt my daughter will be running biodiesel, so this condition shouldn't be replicated in the future. Take heed, you have been warned.

vacuum to leak out into the anti-vacuum. I simply removed the superfluous actuator and its attendant Y-connectors. So the trunk and fuel flap no longer self-lock? Feh. And why _remove_ the flap lock anyway? Just cap it off. Umbrage courtesy of my automatic PO-detection system. Don't be 'that guy'! :-) -- Jim
Re: [MBZ] Notes from the field: 123 vacuum issues
I don't require a fuel flap lock. The trunk lock still functions, but I don't have any spare Y's, so I just spliced in some straight hose to the trunk actuator. She will undoubtedly be the vehicle's final owner, since her recent history has shown a staggering propensity to flog and abuse her car straight into automotive Valhalla--a missing fuel flap actuator will be the least of concerns for future sleuths.

Re: [MBZ] Notes from the field: 123 vacuum issues
I've been known to do the same, but when I drove older diesels, they were my only transportation. It was easy to disable some unnecessary function then to make it right 2 weeks, 3 months, well, maybe 2 years later in one case...

Re: [MBZ] Notes from the field: 123 vacuum issues
Suggestion. For a quick-and-dirty, plug the lines that go to the door locks, etc., at the t and leave vacuum going only to the IP shutoff and (if applicable) to the transmission. MIne's been that way for a while and no issues.

Re: [MBZ] Notes from the field: 123 vacuum issues
I had noticed the e300d had a nice blob of black goop from BioD at the fill neck. Bound to be making a real mess of the fuel lines. I better stockpile some lines so that I can tear into that once it starts spewing fuel all over.

Re: [MBZ] Notes from the field: 123 vacuum issues
If that is the case it might be an idea to replace the rubber fuel hoses. Perhaps drain the tank and see if the strainer is clean, new fuel filter could be the go. From experience bio-diesel causes all sorts of problems. - Original Message - From: Zeitgeist [EMAIL PROTECTED] To: Mercedes Discussion List mercedes@okiebenz.com Sent: Sunday, April 01, 2007 11:40 PM Subject: Re: [MBZ] Notes from the field: 123 vacuum issues Follow-up: Thanks to all who responded, and those who didn't should feel deeply ashamed.

Re: [MBZ] Notes from the field: 123 vacuum issues
The vacuum diagrams in the shop manual (see 80-260 and 80-900/901) are pretty good. Get a mitivac and a couple of golf tees. Then lift the carpet under the passenger's feet and check the circuits one at a time against the diagram. As I recall, all the circuits except the left rear door lock can be checked there. The other possibility is a leak or bad check valve under the hood just above the oil filter housing. Other good stuff to have on hand are a couple of spare rubber Y couplers and X couplers and especially some rubber hose. A leaky vacuum storage tank takes patience because it takes a lot of pumping to build up any vacuum so a leak also bleeds down slowly. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Zeitgeist Sent: Friday, March 30, 2007 22:16 To: Mercedes Discussion List Subject: [MBZ] Notes from the field: 123 vacuum issues So, my el cheapo '84 300D has become a hot commodity for our 21 yr old daughter who recently had her parked Volvo 7-series totalled by an inattentive driver down in San Diego.

Re: [MBZ] Notes from the field: 123 vacuum issues
I know it needs lots of front end work, 'cause it chews through tires at an alarming rate (inners wear really quickly). The TD was doing this also, was one of those things I was gonna get a round to. My son calls one day and says the front wheel fell off as he was turning out of the school parking lot onto the street. Sho nuff it did, the upper ball joint broke/snapped right out of the control arm. $80 tow home, then a few days of front-end rebuild in the rain and other unpleasantness. I suggest you tend to that symptom ASAP. --R
