Yep, although 2.5 may be generous. it does get about 100+ smiles per mile though and several time that are my own. I think that is why it has a 250 gallon tank and 1500 gph pump, so you can drive to the next gas station. Sure is fun though.

58' Mack Model B-21, fully enclosed cab, production number 010 originally ordered for Seattle Fire Department number 246. 1,091 ci Hall Scott engine, 350 hp, and 1,000 lbs torque at idle. Beautifully running engine! 5 speed Mack transmission, 1,500gph pump, 250gallon tank, 82,000 miles, very solid, rust free truck. Partial restoration done by Seattle fire department in 1982 including upgraded air parking brake, and 110v converter. Needs paint, and a place to store it in, runs and drives great. Excellent candidate for shows or parades. Only 9 of these B-21 were ever produced, of the 9 produced, only 6 trucks total came with the 1,091 cubic inch Hall Scott engine. Exceptionally rare old truck that I am posting here before posting anywhere else. $12K OBO

This truck will be going up for sale soon.

its a long hood for sure

I am putting 010 up for sale to a good home soon. I will get something posted up in the for sale section. Now that they are both up and working, I don't need two even though I like having two.

just have to say the sound of 1092 cubic inches growling is amazing, I cant get over the thunder this makes. it is very unique. We had crowds around every time it started up. it drove amazing.

this was a fun day as the Mack did great, but my 48 chevy was having temp issues.

Ok, I am back, fell of the internet for a while but I have been working. I actually have them both up and running, driving, stopping, Maintenance all caught up, and man what a ride. My son and I ended up taking old number 9 to the good guys car show in Puyallup Washington and showed it there, as well as taking them down to car shows in Kent and Auburn, what a bunch of fun. I will post up some pictures in a few.

Sorry I fell of the map, I have been working on lots of stuff lately including both B-21's and forget to get on here and let you all know how things are going, I will update more info in my original thread.

I know this is an older post but can anyone help point me in the direction of where the bleeder valve is located? I cannot find it anywhere protruding from the unit in the truck. do I need to disassemble the unit to get to the bleeder?

Mine were both Positive ground. How did I know? Since they came that way, I checked the diameter of the cable post, and they fit positive post to the grounded cable, negative post diameter fit the starter side cable, so I knew that was how the last battery was installed. Not really sure there is any advantage to switching it over unless a guy was determined and really wanted to go to all the trouble. Maybe I would do it if I was going to install lots of modern electronics.

Ok, here is the finding of the truck and pulling it home, with first start up and drive. longer video with the surprise at the end. My son did this video for me to share with all you Mack guys. He wants to do more of these and we have lots of work to do still.

So here is what it is supposed to look like. pictures from the Seattle antique fire department.

yes I did, I will be happy to email this info to you.

So you are correct, and that is what has me the most concerned. No the water inlet / outlets on the side of the truck were not covered, however they do have the Grates / screens over the main inlets. the tank was covered, and the drains are all open, so I really do not know what is in there. I didn't want to turn it without knowing whats inside. Flushing water through there may be a good idea, but it may also push crap into the pump, I was hoping that there was am inspection cover that would let me get a better feel for what I am dealing with. I do have a long bore scope that I will fish into the inlet and see what I can see.

Recently picked up this truck and would like to see if the pump is working, but I don't want to turn it without knowing about it or what to do to test and try it before turning it. any suggestions would be good. It has the 1500 pump. Water drain is removed, and everything looks good from the outside, just not sure about the internals and where to begin.

Yeah it definitely has the bass, you can just feel it hitting on each cylinder. No need for throttle when moving around, plenty of torque.

Man it's amazing every time I start it. Here is another photo of the twins

Here is a picture of the twins.

Starting up for the first time. Took a little while to get the fuel flowing. Here's a link to YouTube my son posted for better quality.

Excellent, Nice truck! Thanks for the picture, That is it.

Well number two is also up and running, although after about two minutes of running I blew a oil line. My son did take a "startup video" of it and when he gets it finished I will post it. Ran beautiful and smooth once it got fuel. Anyone know which Dog emblem I need to buy to fit the hood? I purchased some B-Model dog emblems for the hood but they are too small and angled up, the hood outline of the Dogs are standing flat and about 2" bigger.
