As said above and welcome to the forum! Pics are always appreciated. Vlad

I would guess if you had cleaned that breather earlier the truck would eat all the organic from the tank even together with algea and alu brightener. But that's of no matter now and doubtly you would like to provide experiments putting the old tank on and putting old dirty gas in it. P.S. The girl worth a half of the thread.

After reading that I wouldn't mind any sealing of the new tank. Just put it on and be happy. On the other hand (my usual thrifty approach) I see no principal troubles cleaning the old tank and use it. Algae is not corrosion so can be separated off the walls. I'm not almost sure on the principal of its build up but as long as we concluded the origin is penetration of humidity into the alcahol that means we deal with water of some kind. If so the derbits could be products of aluminium corrosion (what is doubtful) or organic reactions in the water. If so you should clean it with stuff which dissolve fat or other organical dirt. Something of what is used to clean clogged kitchen sunk. Sure after test application on another aluminium part.

That idea of putting epoxy sealer (not a DD screamer) into the new tank was floating over my mind. And I didn't point that out since in a case you have a clean brand new tank the straight simple way just installing it seemed very attractive. But on the other hand considering options and adding some reasonable amount of efforts into a deal could pay off in the future. I don't see any issues applying sealer to a new alu tank. Sure you should check out the particular compound on its applyability to alu. Also you better degrease the inside of the tank with suitable degriaser before sealing and be sure that light evaporating stuff to not poison your breath of make big boom. On the other hand from those arguments above the worry of use alu tank for gas is water which could get collected in the fuel because of alcohol. But I guess water wouldn't affect aluminium really fast even being poured clean right into the tank. So adding fuel stabilizer and not allowing old gas to take place for a long while should secure you quite enough from notable tank inside corrosion.

The engine you see on the pictures is 2 valve since you can see injectors aside of the valve covers. So that could be 865 or 866. E9 (and also E7 and E6 4V) had lager (wider) valve covers and injectors aren't seen at the outside since their location is in the middle of the 4 valve seats in the cylinder head. They're put straight vertical in relation to piston and hidden under valve covers. Looking by overall design E9 was built basing on those prdecessing 2V V8's but with 4 valve heads. The displacement was enlarged though. ENDT-1000 or (and?) 1005 were 4V engines and looked very close or similar to a E9. There was a post a long while back with pics of an experimental R700 which had ENDT-1005 under the hood. Looked very similar to a E9 (4 valve heads). I must be having that pic on my hard drive, just need to rifle through it to pull up. Hope our discussion in this particular case adds attention to the thread and helps selling the truck. Not just a flood up.

Too possibly you're right. There was a not almost clear to me fact when Mack switched from gen 1 to gen 2 Superliner. 1st the 1st gen was originally produced (and designed) at Hayward factory in California and than after close of that factory in 1978 (or 79?) the production continued at Macungie. Than in 1985 the model was swapped by 2nd generation which was physically a different truck. With different chassis, front end, the line of engines and trannies, style of fuel tanks and updates to the look. But I guess some particular trucks could be (custom?) specified with components basically used on earlier or later models. I have no relationship to Mack factory. Learned the most from info on this site during the years.

BTW you seldom see such fashiony looking trucks on a road in Europe. The most countries in the central part such as Germany, France, Belgium usually operate single axle units with middle rise cabs of single white or red color or so. I bet those on the pictures were imported from Scandinavia. Icey roads and heavier allowed weights predict the 2nd drive (or tag) axle and attractive look prevails over cost savings. Bullbars (or elk bars?) are a common thing too.

A candy! A pleasure to look at!

I have opened heated Bulldog mirror apart once or twice. Don't remember seeing any separatable heating elements. As I remember the heater was glued up to the back side of the glass or integrated another way.

That was also a question to me but the added photos show 865 or 866. Which is period correct.

I doubt any 1st generation Superliners were produced with E6-350 4V since the engine came into production in 1985 and the 1st gen was cancelled in 1984. Or were there some bunches produced near the overlap dates?

I think that's colors of a certain spedition in PA or OH. Very clean looking MH indeed.

Tom, many thanks! I have already had this one in my 'puter but as we say there can never be too many trucks! The one on the picture is the most probably R688 with thar R700 big grille installed. For some reason SGT R-models didn't have classic later R-model grill installed at all or had the appearance as on this picture. Speaking the tanks there were two of them at each side. The main one was that long so had to be hanged by 4 brackets. That's a factory configuration tank but probably the longest avalible option. The 2nd set was for fuel. I tell that by a point which was mentioned in a build sheet for my truck. Two additional aluminium fuel tanks of certain amount of gallons were specified. What's interesting my truck, along the 4 others imported to Russia as a bunch, had those tanks specified in the build sheets but never had them installed for some reason. I could see the mounting holes pre-drilled in the rails but no appearance of any brackets ever attached to there.

My guess is the most observers would "not see the forest because of trees" in the particular case.

Those are cool looking units. And looks like they suited the sevices very well. Definitely different principals in design and different engeneering and trucking culture. But that must be cool when you have choices.
