My drivers square tank has a leak, and that has me thinking again about how to put something a bit more flashy on instead of the old painted square tanks. How available are they? My only issue is I would need two passenger tanks(short one) as I have dual stacks and can't run a long tank on the drivers side. Would the step line on correctly, or be too far forward when switched around? What kind of money do they bring(not all beat up)? I would need the mounts also. I have access to actually build whatever I need, but thinking if I could just buy something that just bolts on would be easier right now(if the price is right). Just putting feelers out there.

Ok, here a question for the gurus. I'm going to pull each fitting apart this weekend and replace any damaged O-rings. Question: What can I use beside PAG100 oil to lubricate the O-rings? This oil is not very substantial and even after applying it liberally the O-rings still went on very dry and I was concerned that it might not work. I was right, they leak somewhere. I know I don't want to contaminate the system, but there has to be something else I can use? Vasoline?? KY Jelly?? LOL!! Sumthing with some substance to it.

Ain't cheap from what I've heard. Don't know it if it true or not or depends on what you get done and by whom.

Wow!!! Now that is old school truck'n!!! V8, mercury sleeper and all. You're a very lucky guy Dan.

My old 673 runs pretty well too. Can't complain for the 14 yrs of service it has given me. More power would be a plus. Don't have the budget for it no matter what I dream about unless someone is giving one away?

That is what I'm thinking. Or just drive it like a 5spd. Seems from what I am hearing, the powerband is at too low of an rpm to use tight splits. It needs to lug down to 1100 to make maximum torque. Seems like it would just be making noise at 1800+ rpm. I'm thinking now it might be easier to find a 237 and make it a 250 then try to find a 250 thermodyne?

Hold up on that car wash boys..............

300 or 300 plus. One is Maxidyne the other is thermodyne. Don't remember which is which.

Thanks for the info Glenn. Not that I have any motors in line but knowing I can make a 250 thermodyne out of a 237 is interesting. Figured that the 205 couldn't move the fuel.

Interesting read Glenn. So basically you can take a 237 and put a thermodyne pump to it and make it more like a 250 thermodyne style engine? Maybe not quite the same HP, but better then just a turbo on a 673 na motor. I would suppose it would be the same with the two different 300 motors?

Well I haven't had time to get to it so I guess I won't try air. Hmmmm. Don't want to waste 134 on it. Boy don't this suck..... Ken. Yes that one.

The cheapie $10 version. They have the bigger electric versions like I saw online for $150. The air version seems to work so far. It did draw it down, but with the leak it would not go beyond 15 in of vacuum. Ya, I figured since the system is meant for 100+ lbs, I could put 20 or so into it and then get the spray bottle out and see where it leaks. Be easier then tearing each fitting apart to inspect the O ring. When I put it together, I used the PAG 100 oil to lubricate everything. But, that oil does not seem to be very slippery and I still was hesitate about how well it would seal. I found out, I was right. I'd rather use like Vasoline or such to get things to really move around easier, but not sure if that is compatible.

Got me a can of 134a for $120 from my buddy at Napa. I also picked up one of those air/vacuum pumps from HF. I hooked it up and it pulled a vacuum.........only problem is I have a leak as it won't hold. As soon as I pull it, it drops to zero. Ugh, time to start going fitting to fitting. Wonder if I could put some air pressure INTO the system and use soapy water to find the leak??

I've heard differing views about using a 237 behind a du/tri/quad. Usually just skip splitting the gears. No need to, and the way the power comes on with a 237 it just doesn't like to be short shifted. I can't say for sure, never driven one. Had the same reservations about using one in my truck. I like all the gears(so far) and I guess it would be a change not having to change gears every 10 seconds. Can you just put a thermodyne pump on a 237 and make it respond correctly? I would suppose there is A LOT more to it.

That was my thought. Didn't know if it had rubber seal or just tapered seat

Truck looks good! Don't worry, the shifting thing will come to you with practice. You shoulda seen me my first summer!!!

$2500??? Can't get a decent 300 out of Adelmans for what that whole truck went for!!!

Our local driver from CCX, his take on the interior cameras? Fkit. Was told not to smoke, he lights up and then flips the camera off. He is allowed only 3 write ups. He has yet to get one. He's been at it for LOTS of years and just waiting for them to cancel his ticket. Hasn't happened yet.

Just have to look in any of our company vehicles. It just baffles me how people can screw stuff up? OH, that's right..........IT'S NOT THEIRS!!!!!! Of course their vehicles resemble it too.

I noticed last year a couple of the lines are damp at the pump. This past winter I just loosened them a touch and then resnugged them. Ran the truck last Friday night and don't notice any real leak, never was bad, just damp at the fitting. Is there a rubber seal that can be easily replaced? Don't want to open a can of worms just taking things apart to find out.

I only started when Kevin from ATHS said we should try it. I don't do much with mine but it does come in handy sometimes. Some people are post whores.......I ain't one. Request sent.

Now that the truck is fully operational maybe I'll send my money in?

Well I took the truck for a ride tonight. Steering works fine. Going to take getting used to. Sometimes it is almost too light then sometimes it gets heavy. Running down the road it was fine and didn't feel loose.

Yup. It turns down the front air pressure so to not slide the front tires on a wet road. Back in the earlier days, tandem drive trucks did not have front brakes. You had to have two axles with brakes, so they eliminated the front axle since it just slides with minimal weight on it.
