I have an 83 240d 279k on the clock 4 speed manual that runs like a top until yesterday. I decided to install my greasecar kit finally that i pulled off a same year volvo.

what happend i was driving around for a couple weeks with the tank in the trunk hooked up the wiring run to the 3 way valves and the valves connected to the wvo tank but nothing connected to the engine just yet.

I Followed my greasecar setup and checked it twice the car started right up but sounded like it was running low on fuel until it died out I could ad some fuel and get smoke and sputter but nothing that would stay on. I have work and school tomorrow so I started putting everything back.

I ran all new clear return lines above the injectors and clear lines to replace my worn out ones from the IP to the spin on fuel filter after pumping the primer to get most of the air out the car wont even sputter now.

I have tried the following voltage at my number four glow plug was 11.5 Volts while cranking my glow plug light is intermittent

very little bubbles appear on any fuel lines. If i loosen my fuel injector lines working with only one at a time and crank it for 15 seconds I had fuel foam originaly but no new fuel from cylinders 1 and 2 . 3 and 4 were dry from the start and nothing came out.

with a battery charger hooked up to a moderately charged battery I ran a hair drier down the intake manifold blowing very hot air no sputter nothing

I think fuel isn't moving please give me some advice I'm afraid I might need a new IP the greascar setup removes the small filter and runs some bypass lines. I ran my old greasekit lines did clog my pump or damage it buy cranking it to much?

I would like some advice on some part to check I will take pictures of the engine bay and the fuel lines filled if that helps.

Is anyone good with a wrench from southern California I would rather give a member some cash for helping me fix my problem than a dealership.

If someone knows an ok shop I can go that route I'm just looking for options now thank you

Joe

Sounds like you still have air in the system. Pump that primer pump a hundred more times and you'll finally get the air out. I pulled my lift pump the other day and it took me about an hour's worth of pumping and pulling with my mity vac to get all the air out of the system. So keep pumping until you get absolutely no air. Then pump some more.

When you install a two-tank kit in one of these Mercedes, you need to re-route the fuels lines at the diesel filters, as well as plug the banjo bolt on top the spin-on fuel filter. Did you do this originally? If so, did you make sure to get it back the way it was?
I agree, it sounds like you have a bunch of air in the lines...you'll have to pump a lot to draw the fuel up to the IP, or use a mityvac on the return line to pull fuel to the pumps.

If you need local help in socal with your VO system (or just mechanic help), a guy named JeffnLisa on the frybrid forums installs VO kits, his email is dandsins (at) yahoo.com

I would try to swap everything back to stock and make sure it runs, that would let you know for sure that it was a setup problem like air in the lines or maybe a clogged stock fuel filter. That would also let you get to work/school until you have time to mess with it.

I got a larger siphon starter thing that I can fit the fuel line in and suck air out of it. That made it a lot faster and easier to purge the line. I got it at my local hardware store, cost me probably $3.

I need to plug the banjo that has the three way tee on it? I think i'm going to ask for help from Jeffnlisa i'm new to mercedies and would like a bit of experiance under the hood.

ps i pumped it some more and used a might vac at all the steel injector lines installed new fuel filters and i have the sytem completely back to stock thank you and everyone for the feedback i'm going to check my glow plugs tonight and try to pump it many more times if i pump and fuel comes back up from the pump is something wrong?? I just thought i would ask

Joe

Just wanted to beat him to the punch

Yes, the banjo bolt on top the spin-on filter where the injector return lines and IP return line connect...you need to take that bolt out and replace it with a solid bolt or plug the bolt with JB weld. Otherwise, the VO will drop down into the diesel filter through the bolt.

What do you mean "if fuel comes back up from the pump"? If you can pump fuel at least to the IP, you should be able to crank until it starts. I don't remember how much I had to prime when I re-routed my lines, but it wasn't too hard to get started again. Definitely check the glow plugs. And I emailed JeffnLisa to let him know you might be contacting him. He's waiting to help you

Shhhh, I might get banned for those kinds of comments.

Try running it on diesel in a bottle similar to when you do a diesel purge. Get some fresh clean Dino-Diesel and then run the fuel lines into it. The line that has (or had) the plastic filter is the fuel in line. The line that comes from the top of the secondary (spin-on) filter is the fuel return line.

Take the spin-on filter off and fill it with diesel as well. This will help eliminate the need to pump the primer 100 times

See if it will run with this set up. You might have damaged your lift pump trying to move heavy (unheated) WVO...

just FYI; a great site.

You can find a solid banjo bolt which will make sure the fuels aren't mixing. In addition to what the others have suggested, look at your vacuum hoses as you probably knocked one or more out of whack while installing the system. When I did mine, I lost the shut down feature intermittently, which was a pain until I found the old cracked rubber bit to replace. The injector return lines (cloth covered rubber) can also be ancient and brittle and when you move them they start invisibly letting in air.

It does sound like you're sucking air, but it should at least crank. Depending on how you had it set up, you may have shot some SVO down the return to the dino tank. If it was cold or not filtered it might be clogging your fuel tank screen.

If you get it back to stock set-up, don't mess around with opening up all of the metal lines, injectors, etc.- Make sure everything is tight ('cept your fuel filter, duh) and that your primer pump isn't the source of the air leak and prime away.

If you somehow injected cold svo, you may have some mess to clean up...

alright My primer pump was pulling in air with every pump and leaking out a bit of diesel. WVO never hit any part of the system as i just hooked it up w/ an empty WVO tank running lean My glow plugs got hot and I burned one. Doing everything I could was no match since the pump wasn't working through the leaking primer pump. Changed that out from the twist pull pump style to the newer pump only style and changed my one bad glow plug measure them two ways resistance from relay and w/ a current meter to check current draw after 15 seconds or so.

so culprits leaking primer pump and bad glow plug it used to start ok on three decent ones but now it runs better than it used to even on cold mornings.

I sent an emal to jeffnlisa when he has time i hope he'll help me out w/ my wvo setup

Joe

I want to thank everyone for the help! next time i hook it up i'll do it with some physical help and use plug for that banjo bolt. i did not do this last time and i'm sure that didn't help things.

ps i found a great guy near me 92821 brea california who loves working on these things

star auto on viking off of imperial highway great guy

another good 240D ruined by WVO.

From the standpoint of an honest MB technician, Vegetable oil is a threat to your diesel engine's mechanical integrity.

Has nothing to do with the veggie oil other than he opened the fuel system and has a whole lot of air in the system that needs to be purged out. So quick to blame WVO.
