If you cut your trans cooling lines and replace them with rubber hose and mix them up is it ok and if not how do I know witch way to hook them up on a 2004 trailblazer

If its the metal part of the feul line cut out one end and about a inch on other cut with grinder so its a clean cut and get a rubber hose gots to be feul line hose make it half inch longer on both side get 2 hose clamps small and put the feul line on with hose clamp on each end

dirt or rubber in main jet
have the carby professionally overhauled
replace all rubber hoses from the tank to the carby, including the fuel pump
if you use e-mix fuel then it could also be a water problem and corrosion in the carby

They rust, the hoses crack. Replace both.

You've got two options: Either cut back the line to a point where the line is still good and either replace the rotted section with steel line using compression unions, or use rubber hose in the same manner only when you put mini clamps on the ends, make sure to use two at each end with the screw parts 180 degrees from each other and about a half inch apart. Make sure if using hose that you push the hose at least four inches up onto the existing line. It's best to use clamps used for fuel injection hoses as they don't destroy the hose.
When running the new line, it does not need to exactly follow the routing of the old one but needs to be secured so it doesn't vibrate and does not run too close to exhaust pipes or any moving components (steering etc) that can wear a hole in it or cause the fluid in the line to get hot..

I cant find any diagram for the routing of the lines.Most of the time it is just a fitting and these can be purchased from parts stores and the dealer.You can repair lines if a hole is rubbedin the metal part by cutting and using a compression fitting to repair.If your model has rubber hose at the radiator end then you will need to replace it with transmission or power steering hose.Do not use feul line or plain rubber hose.These are not made from the correct material and will swell and burst.I dont care what the guy says at the parts store feul line is not ok!Unless you have a HD truck you should be dealing with 5/16 (8mm) metal and or hose.Clean the leaking area with brake clean and get it dry , make sure transmission is full and crank the truck and let it run while you pinpoint the leak.Good luck and let me know if i can help.P/s if you decide to replace the lines you can purchase the bent to fit from the dealer.Dont try bending yourself ,it has taking me years to master this.

I think that it is not a vacuum hose
most all trans went electric shift in 1995
if the hose is coming from the tran check and see if it goes to the top of the tran
and it will go from rubber line to metal tube
I think your looking at the tran vent
and does not hook to the motor
get back to me if that's what it is
leave some feedback
good luck

probably trans cooler lines if it looks like its coming from radiator area probably will haft to replace hole radiator there one of the same check lines closely they run close to each other have been know to rub holes in them very likley if it is line leaking cut bad piece out use a good rubber line to replace use two clamps on both ends of rubber line good luck hope this helps

Most likely the rubber hose at the end of the metal trans lines, where they connect to the bottom of radiator
I would disconnect at the trans,cut the rubber hose off,and lay it out on the gound,where you can carefully cut off the furrell and just replace the hose using a clamp on both ends.

You are referring to a transmission cooling line, connected at the radiator, running back to the trans? Is there a leak in the line? If that is the problem, you can do a quick fix as long as you can determine where the leak is. Cut the line at the leak, using a hack saw blade (the more 'teeth' per inch= a finer, easier cut). Slide a piece of rubber gas line (purchase it by the foot at any parts store) over the trans line, install a small hose clamp at each end, check the fluid level, and you are good to go. This fix will last for a LONG time. If you want to replace the entire line, you'll need to remove it and bring it to a parts store, so they can match up fittings so you can re-attach a new line at the trans and radiator. Line is sold by the foot, and you will need to bend it (carefully, so as not to kink it) to match the original. 2 or more sections of line can be joined together by connectors to make any length you want. Using 2 or more sections will make it easier to 'fit' the line in place. Purchase brake line wrenches to use to remove the lines at the radiator and trans, they work better than regular wrenches (you don't have to buy these, it just makes the job a bit easier.

Do u need to replace a damaged or rotted section of trans. coolant line? If that is what u are asking, just purchase a section of rubber gas line and hose clamps, cut out the damaged section, install hose and clamps. Works great.
