Where do you see the air? If ther is air in the fuel, look on the suction side of the fuel pump all the way back to the fuel tank. Check every connection for tighhtness. If the hoses are old and cracked, replace them and the clamps.

Also for fun tighten the fuel pump lift screws if it is a mechanical pump.

Good Luck

SOURCE: air in fuel line between fuel filter and injection

Hi, before the pump it is a loose connection or maybe a pin hole in the pipe, check all the connections and pipes for seepage, after the pump it will be a leak, i knowit sounds the same but after the pump the fuel is under pressure. It would appear that your system drawing air rather than forcing air in. daveg

no it wont but a cloged fuel filter will increase the pressure from tank to filter and overload the amperage in fuel pump and posibly burnt fuse also check for bad engine mounts if engine moves while is under load it might contact some wires and burnt fuse

SOURCE: brake line leak, between frame and fuel tank

You should be able to re-route a new section of line w/out any trouble. If the line is leaking due to rust, you might want to replace all the lines at once, since the rest of the system is probably rusting away also. If you plan on keeping the truck for a while, all the more reason to replace it all. I must add, I hate those rusting brake lines! Did mine over 2 times on y 90 F-250, salt and snow plowing do a number on them.

Have a 1986 golf diesel it ran out of diesel and I

Are you certain that you put diesel fuel in the car? Had to ask that question. How long did the car sit before you refueled? If it sat for a while and if the temperatures and humidity were enough to produce a build up of water vapor, that might keep the injectors from sending "dry" fuel to the cylinders.

Just running out of fuel won't harm the glow plugs (hence poor starting) and won't require need for a new battery unless the current battery was failing even before draining the tank.

Engine cover removal on s-max

I would recommend loosening the fuel filter and then applying air for a compressor to the fuel tank and have someone watch for fuel filter and when it is full of fuel keep applying air and tighten the filter. check for fuel going through the line from the filter to the engine. Then have someone try to start it while still applying air the the tank which will help push the fuel. I used to do this all the time working on semi's and chevy express vans with duramax diesels.

My '78 mercedes had a leaky master cylinder, it leaked into the vac. boost. I replaced it, but now it has no pedal play and when pumped a couple times it seems to keep brakes on a little. Is there an...

You have air in your brake lines. Get that taken care of, you don't want to slam on your breaks in an emergency to have a pedal go to the floor.
I think Walmart sells a brake bleeding kit, though I've never used one. I can tell you a process I've used though...
You'll need two people, one in the car ready to pump brake and the other with wrench in hand ready to get a little brake fluid on them. :o)
On each wheel next to the brake line connection, is a fitting. It looks like a grease fitting, but it's your bleeder fitting.
Loosen the fitting then just snug it back... to get ready. Tell the person in the car to pump the brake pedal and hold it! Slowly loosen your fitting again. Either air, or fluid will come out of the bleeder. Bear in mind, as you do this, the pedal inside will go down. Inform the person to keep their foot pressed to the pedal at all times until you tighten up the fitting again... else, when they lift, the pedal will **** air back into the line. Do this several times untill you are sure all of the air is out of that line. There should be a steady flow of fluid only.
Make sure your fluid level is full in your master cylinder too! As you lose fluid, you want don't want to empty the supply... air again!
Do this same procedure on all four wheels. You'll have an air free brake system!
Now you're a pro! Next time I need my brakes bled, I'll call you... ha
Good luck, hope it helped.

Car wont start on 206

you must fill the fuel filter housing with diesel to eliminate air pocket. if you don't have diesel, fill it with automatic transmission fluid. it will smoke for a few seconds, but it will run so fuel pump can catch up. don't touch throttle for a few seconds till you know that it is running on diesel and the tranny fluid is all used up.
