Earlier this morning i ended up driving around for approx two hours looking for the 3/4x 1/2 x 1/2 tee I need to use for the new TITAN tank i recieved a few days ago. This is the only part that I need. I drove to 2 different Home Depot stores, 2 or 3 auto parts stores and I could not find the 3/4 x 1/2 x 1/2 tee. The only thing that i can think of is that this tee does not exist and you guys are using pieces to make a tee. The closest thing to black plastic at Home Depot is some kind of grey plastic fittings and the only tees are 3/4 and 1/2 inch. I did recieve in the mail with my missing parts a 3/4 x 3/4 x 1/2 tee and i do not think this will work. It might work if i change out the hose on top of the titan tank to 3/4 inch and buy a different fitting to go to the back vent. Please help me with my situation as i cannot find the correct tee that i need. I do hope somebody out there with a TITAN knows what to do.
