123, Diesel Engine

Now in a pak of 25 for even more savings. These are my favorite European hose clamps. They tighten securely, don't cut into the hose, and don't rust or break. If you are working on an SVO  fuel system for any Mercedes I recommend you have these clamps on hand. Cheaps clamps can cuase air leaks leading to great frustration- the US style clamps with holes that cut into the rubber. These clamps will work on all 8 mm hose, 5/16 and 3/8 US spec fuel or coolant hose.

For use with our all fuel specification SUPER FUEL HOSE. CLICK HERE to read more.

NOVEMBER SPECIAL: BUY ONE AND GET THE SECOND FOR HALF PRICE! (If you don't have two cars you should carry a spare in your trunk - failure of this part has proven to be the number one reason your Benz will quit and won't crank over to restart).

If you are going to buy or have just purchased an older 5 cylinder Mercedes Diesel (1975 to 1985) the first thing you need to do is a good physical exam of the engine. It is even better to do this BEFORE you purchase the car to prevent surprises and pain in your wallet. Check out what happened to us recently in our PROJECT DRIVEWAY restoration by CLICKING HERE!

This genuine Mercedes seal fits on the top of all 5 cylinder 617 turbo diesel engine air filter housings from 1981 to 1984. This is the hard to find seal that fits just below where the breather tube plugs into the air filter lid.

If your wagon fuel gauge is jumping around or reads inaccurately the sending unit is usually the culprit. If you have been running bio-diesel then for sure it is the problem. Bio-diesel is pretty rough on sending units. Location is on top of tank under the rear floor boards. List price is $262.00

Fits all Mercedes Diesels that use the 90 degree fuel prefilter. This prefilter is made by Hebmueller of Germany and is excellent quality. It has brass inserts in the ends so they cannot collapse or crack when the fuel hose clamps are tightened down. Now sold individually! If you want more than one, just change your quantity in the shopping cart. We also sell these in a six pack for a better price break.

Diesel purge is amazing stuff! It is getting so popular that we have decided to offer it on the website individually, so now you can buy per can. This injection cleaner is run directly through the fuel system in the engine compartment. It is not a fuel tank additive. Does not include instructions or bypass hose. If you want more than one can just change your quantity in the shopping cart.

INTRO SPECIAL! Lubro Moly Diesel hi test fuel additive. Formulated for the new low sulfur diesel fuel. Contains an additive against injection pump and injector wear. Keeps the injection system clean. Provides clean, low smoke combustion. Regular use guarantees lowest exhaust emission levels. If you are running petrol diesel it is a must to be using a fuel additive in the older Mercedes diesels. Sold per can, treats 20 gallons.

These are the zip ties we have all been looking for. They have a super sticky tape of the foot of the tie so you can stick them anywhere in your engine compartment without having to drill a hole in the inner fender panel. (NOTE: Be sure to thoroughly clean the surface BEFORE installing). The other neat thing is that these zip ties can be loosened back up (just like the factory type) to remove the wire bundle or anything else you need to secure. Sold in packs of 6. You will love these!

You have asked for it and we have delivered again. Now that all those old power steering pumps are leaking out the front seal we have come up with a kit that will allow you to replace the front seal of your pump at home without any special tools. This kit will work on all power steering pumps on 4 and 5 cylinder diesel engines from 1977 to 1985 (excluding the 190D 2.2).

Kit contains the following:

This is the tool I love to use when troubleshooting engine operating temperature problems. You can stand back and aim the beam right on a spot on the radiator or engine to get an exact temperature reading. This can indicate whether or not your radiator is plugged and confirm if your temperature gauge is accurate or not.

If you are running SVO it can give you accurate readings of the temperature of your oil - both during filtering and coming out of your boost heater.
