CML Service Posted September 11, 2006 Share Posted September 11, 2006 Hi folks, in the process of putting my truck back together I need to add a wet line tank. What size tank should I use? I plan on using it for a 24' dump trailer. Thanks Chuck Quote Link to comment https://www.bigmacktrucks.com/topic/1520-wet-line-tank/ Share on other sites More sharing options...
Lmackattack Posted September 12, 2006 Share Posted September 12, 2006 Well, I added 40-45 gallons of hyd fluid in my 126 gal tank and it dumps and works just fine with low boys and short dump trailers. The amount of fluid capasity needed is dependant on the hyd piston. I havent pulled a long dump but would suspect it needs more fluid than a short dump because of its hight travel? are you running 2 fuel tanks right now? what size are they? if you have 2 large tanks you could convert the pass side to the wet tank. or if you want to be real trick. have a shop seaparate the pass side tank for fuel and hyd fluid. something I considered but dident want to spend the $$$ on.im not a fan of the top of frame mounted tanks that sit behind the cab. ugly in my opinion Trent Quote Link to comment https://www.bigmacktrucks.com/topic/1520-wet-line-tank/#findComment-7490 Share on other sites More sharing options...
CML Service Posted September 12, 2006 Author Share Posted September 12, 2006 Hi Trent, Are you saying you are running your system with 40-45 gals ? I was thinking of mounting another fuel tank on the driverside. I have a nice 40 gal tank fuel removed from another truck but I was thinking it may be too small. I think I may have a 50 gal still on a truck that matches the drivers side tank. This is one of my B models and it has 50 gal lf 40 gal rt.

Lmackattack Posted September 12, 2006 Share Posted September 12, 2006 I dont remember the min amount of hyd fluid I needed for short dumps but I think I was told 40-45 gal min? I added about 5-7 gals more because I used the large 126 gal pass side tank and was worried about it sucking dry if I was dumping on an incline. Most of the trucks here in the city use the pass side tank for hyd fluid regardless of the size. The tractors set up from the factory for a dump tractor would have a amall 50 gal pass wet tank and a 100-120 fuel gallon tank on the drivers side. my opinion is anyone trying to save weight would just use the pass side tank for hyd and have only 1 fuel tank.my 2nd B had a rectangel wet tank mounted behind the cab. it was pretty small but I guess it did the job with short trailers? never did use that tank but it was small!I have also seen many trucks have 2 fuel tanks of the same size and then the wet tank behind one of them, any choce is fine but I would rather use the frame rail space for something more usefull. on my RS I was able to put a 24" long tool box on the drivers side rail. Was a much better idea than a wet tank located there.Trent Quote Link to comment https://www.bigmacktrucks.com/topic/1520-wet-line-tank/#findComment-7493 Share on other sites More sharing options...
HK Trucking Posted September 12, 2006 Share Posted September 12, 2006 I can tell you that for a Quad axle dump truck with a 156" stroke cylinder, 35 gallons is enough.when I've drained systems & refilled from scratch, thats how much it took to fill it up & top it off after bleeding the hoist cylinder.However much longer your cylinder is on your trailer you could estimate the gallonage accordingly.

CML Service Posted September 12, 2006 Author Share Posted September 12, 2006 Thanks for the input folks. I think I will try to use the 50 gal tank that way there will be air space even with 45 gals of oil.

Lmackattack Posted September 12, 2006 Share Posted September 12, 2006 one thing I would recomend, as you are scratch buildng the system, is to add a 2 line wet kit. this would allow you to pull lowboys if you ever need to move one. something good to have and easy to install with all new parts.

CML Service Posted September 12, 2006 Author Share Posted September 12, 2006 Thanks Trent, I plan to install a two line system just for that reason. I found my good 50 gal tank today. I cut a large hole in the top to clean it and to weld supports for the feed and return piping. I've seen some tanks crack at the bung when valves piping and hoses hang on them. I'll post some pictures while I'm working on it. Chuck Quote Link to comment https://www.bigmacktrucks.com/topic/1520-wet-line-tank/#findComment-7511 Share on other sites More sharing options...
Lmackattack Posted September 13, 2006 Share Posted September 13, 2006 are you welding the bungs to the end of the tank or on the sides? I had a welder friend of mine install both bungs on the sides for a cleaner look and to hide them. we welded a stiffner plate to the sides where the bung went thru to reduce the flex from road vibrations. let us know how it turns out Quote Link to comment https://www.bigmacktrucks.com/topic/1520-wet-line-tank/#findComment-7519 Share on other sites More sharing options...
