Re: [MBZ] Lost prime in traffic
I had something similar happen; the car would go about 20 miles at interstate speeds then lose powe (30mph max) and then die. If it sat a while it was ok again, but it wasn't too happy right after the power loss bit. My prefilterbwas black too. I had a spare in the glovebox, so I put it in. The blackened prefilter was so plugged it held enough vacuum that it would not empty of fuel even when both sides were opened to air! -- John W Reames jwrea...@comcast.net Home: +14106646986 Mobile: +14437915905 On Jan 25, 2010, at 20:29, hue wong wong_...@yahoo.com wrote: Seems like there may be air in it.

Re: [MBZ] Lost prime in traffic
Late to the game, but here's my input. 1) Microbes (mold/fungus, not algae) have grown in your fuel tank because you have water accumulated in the bottom of the tank. Treat with (1) biocide and (2) fuel additive specifically for water in diesel fuel. May need to deal with a clogged fuel screen as well as replace both fuel filters. Keep spare filters in car along with tools to change. 2) Leaking fuel primer pump. If old style with white handle that you unscrew before operating, and it leaks even the slightest bit of fuel, replace it. Once you have a good pump that doesn't leak, 50 - 75 'enthusiastic' cycles of the pump are required to prime the injection pump. There will be a distinct change in noise and amount of force required to operate the primer pump when the injection pump is primed. Note: primer pump does NOT push fuel out the injector lines - you will have to crank the engine over by the starter to make the injection pump push fuel out to the injectors. After that, lots more possibilities, but these are the two most common issues in my opinion. -Max -Original Message- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of hue wong Sent: Monday, January 25, 2010 5:23 PM To: Mercedes Discussion List Subject: [MBZ] Lost prime in traffic Hi all1 I wanted to tap the collective wisdom of the group.

Re: [MBZ] Lost prime in traffic
Lots of folks use the term algae, but it is really either mold or fungus (or both), which does NOT require sunlight to grow. It only needs water and diesel fuel. Algae uses photosynthesis to live/reproduce; shouldn't be any photosynthesis going on inside your fuel tank... Marshall used to recommend treating your fuel tank to remove the accumulated water every fall, and using a biocide when required. Water will accumulate - it condenses out of the air in the tank with every heat/cool cycle. Keeping your fuel tank full, especially when the car is parked for long periods of time, will minimize the amount of water that accumulates. -Max -Original Message- From: mercedes-boun...@okiebenz.com [mailto:mercedes-boun...@okiebenz.com] On Behalf Of Dieselhead Sent: Tuesday, January 26, 2010 9:39 AM To: Mercedes Discussion List Subject: Re: [MBZ] Lost prime in traffic Algae It kills injection systems.

Re: [MBZ] Lost prime in traffic
I just use a vicegrip or channellocks on the top of the tube to get the old one loose. I finally broke down and bought a crowsfoot to get to the flats on the replacement. Before that, I wrapped a shop rag around the top of the new pump and tightened it with the chanellocks on the top of the barrel. The bear is getting the gasket to stay in place on the descent down into the hole on a 123 300D. I use a little grease on the threads to hold the gasket on. Max wrote: 2) Leaking fuel primer pump.

Re: [MBZ] Lost prime in traffic
If you still have the red-handled screw down type pump, it's probably leaking. Tank could be empty too -- it's not impossible for the fuel sender to stick Check the fuel lines -- if they are wet with fuel, they are leaking air and you can pump until the end of time and it won't prime. Fill the filter with fresh diesel, too -- you may get old trying to start it otherwise.

Re: [MBZ] Lost prime in traffic
You may have a combination of things. a small air leak can become no fuel in combination with a plugged tank screen. Here is my suggestion: If you have more than 1/4 tank of fuel: on the left inner frame rail the fuel and return fuel lines com up from under the car. Loosen the clamps on both. pull off the hoses and swap them. tighten the clamps. Then try the primer pump. If the lines to the tank are dry, it can take quite a while to pull fuel up to the primer pump. If this works and you get fuel, you have a plugged tank screen. You will be able to drive it for a while at least. If it sat through the summer, I would guess you have algae in the fuel. You can buy and algicide at a marine store. Use the shock level treatment Carry spare filters, and change them when the engine is starving. I am assuming this is a 123 300TD, since you said it had a primer pump. The other part of the equation is to change all the rubber hoses from the tank to the transfer pump. a leak in the hose at the tank can also cause no fuel. the hoses will let air in, but not leak fuel, or only be damp, not dripping. If you have not done so recently, you should drain the tank, pull off the hose above the Right axle, remove the body plug. Then you can see the hex of the fuel drain/screen/pickup. It takes a big 3/4 drive socket to loosen. remove the plug and screen. Clean the screen. Put a new oring on the plug, reassemble. Then put on a new fuel hose. the OE from Rusty is the best. Being cheap, I cut the ferrules off the old hose and reuse the fittings with a chunk of new hose and a hose clamp Then replace the hose for the return line. Check the steel tubing for any signs of corrosion, especially under the clamps. A rust spot can also let air in , but not leak fuel. If you find rust scale, replace the steel line. Then replace the hose under the hood from the steel line to the prefilter, from the prefilter to the transfer pump, and the rest of the rubber hoses. The other likely culprit is the primer pump. They often leak, and if they leak, it allows air into the system and that means fuel is not drawn from the tank. If you have used it recently, and it did not leak fuel, bubble or hiss, then it may be good. Good luck. Hi all1 I wanted to tap the collective wisdom of the group.
