I may be proven wrong, but I dont think the tire idea would work. Valve stems are very small and dont pass much air. Think how long it takes to air one up. You starter will require more volume than can pass through a valve stem quickly. Id vote for the little electric deal or one powered be a small gas engine.

The dryer has a heater. Im not sure its getting power. I have to change the heater about once a year. Its cold when I discover the problem. How does an evaporator work?

Its down hill all the way. Once it froze up farther forward and another driver gave me his mouth wash to pour down the line. It worked and I made it home. Most often it freezes just ahead of the dryer which is the lowest point. The line is horizontal where it enters the dryer.

My truck has an AD9 air dryer. In the past Ive tried to insulate the line from the compressor to the dryer but the insulation melted. The reason for the insulation is that the air line freezes and plugs before it gets to the air dryer. Im really tired of this. While Im working Ill leave the line loose so some air can escape. If I leave it run overnight to keep the fuel warm, I may find a blown head gasket on the compressor. Its not a bad job to change but it really screws up a days work. Can anyone offer a solution? Do I need to go backwards in time and use an alcohol evaporator? Ive never used one but have had to pour alky down the line to clear it. I keep a torch on hand to melt the ice plug but again its a pain. No I dont use flame around the alky!

Not to hijack the thread but, Ive got 8 22in wheels on my old Freightliner Id like to move. I havent had time to visit here often. If anybody wants them email farmboymotorsports@yahoo.com. Id be up for trading something, almost anything.

That Davco is the one he's got. His doesnt have the water heat option. Yes he really needs fuel heat. The people at Detroit tell him that if the truck runs for five minutes the fuel is warm enough because they recirculate so much. I think he is going to spring for an Arctic Fox tank heater. He also has a Wesbasto coolant heater. Some days that wont even pump fuel to start. Down here in Iowa the fuel is so bad my Hot Stick was no longer enough heat. I added a Vormax filter which allows for coolant heat. I havent gelled since, but my restriction has elevated from time to time.

A friend of mine has a Freightliner with a Series 60 Detroit. Every time it gets cold he has trouble. He now has about a triple dosage in and the truck still died. Premium fuel(treated to -20F) plus extra amounts of Fuel Saver antigel. This is a cronic problem anytime the temps get near zero. Any help or advice appreciated.

Look for someone that sells Optima batteries. The plates are rolled up with a fiberglass mat between them. The batteries look like a 6 pack. I sell them here in Iowa and use them in my dragster and Ford 9000. My wifes pickup and kids cars have them also. Regular plate batteries let me down twice while racing and the tractor batteries were usually replaced annually. Since going with the Optimas Ive never had an issue. They are more expensive but well worth the difference in reliability.

You can see as it stopped backing up the front end was light. Very dangerous to move a load like that. Do you really want the whole load balanced on the tandems? Have you thought about installing a tag axle?

Ive got a Ford 9000 with the filter under the hood. It makes for clean lines but it picks up lots of heat. Im going to put something behind the cab if I can figure out a way to duct it without lots of restrictive bends.

I just got back to work with my seasonal freight. I cant afford to stop. If I did Id be out of work.

My Ford has the air cleaner under the hood like that and the intake is on the right side of the hood. Im going to put my filter and intake out behind the sleeper so I can use one of the Centri precleaners on it. My second choice is to leave the filter under the hood and just duct it from the back.

I spoke with a used truck salesman. To my surprise he was leading me to Eaton Fuller drivelines or transmissions with only a .7 overdrive. His recommendation was 300 or 350 E7 or EM7 with a 9 or 10 speed, a 3.86 to 3.58 rear and LP 22.5 tires. He said I should run the engine about 1400 rpm. I specified that I wanted excellent fuel mileage. The run is mostly level with no real big hills. Those with experience care to comment?

I did quite a bit of looking for information on the air/fuel separation systems. I found an SAE paper written by a Parker engineer that showed when diesel is put under a vacuum (when being pulled up to the engine from the fuel tank) entrained air is separated out and makes larger bubbles that cause problems. If fuel is fed to the injector pump by gravity(like in a farm tractor) the air doesnt make the larger bubbles and goes through the injectors with no negative issues. I know on my Cat the plungers are filled through a port in the bottom of the cylinder and dont have many of these bubbles to interfere with the spray pattern. Im assuming that the older Macks are the same way. You brushed up against the question with your answer, but its still not quite clear for me. In these newer electronic systems, (common rail?)do they bypass the fuel before it gets to the injector and therefore bypass the air or is the fuel that still may contain bubbles sent to the injectors and bypassed after going past the injector body? If Im not being clear on my question please let me know. Ive tried to get this information right from the engine dealers but apparently there isnt a "book" answer so I have to look elsewhere. Ive tried in vain to find the Parker paper. The Parker website seems to be "busy". I did find these quotes tho: Parker - Racor Technical Support confirms: "Fact #1; There is Air entrained in diesel fuel." Milwaukee School of Engineering, Handbook of Hydraulics agrees: "Hydraulic oils also contain varying degrees of entrained air." Caterpillar®, Special Instruction 651-1250 points out: " Normally No. 2 Diesel Fuel contains about 10% air in solution, although the air is not visible." Cummins® Engine Co., Service Topic 5-135 states: "Like water, fuel contains a certain amount of dissolved air depending upon the fuel temperature, pressure on the fuel , specific gravity and the amount of aeration to which the fuel has been subjected." Those came from the Airdog website. Ive put them here not to sell product but to give you an idea of the answer Im looking for. I hope someone can find the SAE paper Id seen before. Im only trying to find out more detail on the routing of the fuel from the tank to the engine and the return of the bypassed fuel. Thanks for being patient.

Nobody knows anything about the injector pumps??? Perhaps someone knows of a place I could find online info or an exploded view.
