I'm going to be doing a job, and instead of using fittings and couplers, we'll be just root welding the pipe with the 7018. Any tips on welding this small diameter pipe? Anyone think this is the best choice rather than going with a 6010 than 7018 cap? Can't seem to find much online on air line pipe welding
Teflon tape or a little pipe dope. Both are cheap and readily available at any hardware store or home improvement center. DO NOT use glue however
you couldn't use pvc glue with water present anyway, it wouldn't bond. also pouring glue over your leak,(if this is what you are suggesting), probably won't be best fix. NOTE: teflon tape isn't to seal pipe leaks, it is alubricating agent which allows the threads to thread together deeper and seal better, and ease dis-assembly. The best answer replace and re-tighten, if this isn't possible get two part epoxy that says waterproof and can be worked with water present (read packaging). They have split PVC pieces to join over a leak and then clamp.Use together with glue. I have made emergecy repairs like this to hold 100psi.
The fuel filter is located under the drivers door area of the vehicle on the frame rail. it takes a special tool to release the clips in the line on one side and has a plastic clip on the other side which can be removed, the tool is available at most parts stores
Several have said to use teflon tape. However, pipe sealant paste is the best way to go and for the following reasons. 1. Teflon tape is NOT a sealant. It is ONLY a LUBRICANT. So, what it does is it allows you to tighten a threaded joint tighter with the same amount of force on your wrench. This can cause a major problem in that if you place more force to tighten the joint further than it is intended to be if it were without the tape, then you can and quite possibly will crack on of your fittings!!! Then you have an even bigger problem. 2. Pipe sealant with teflon, also known as PST, is the preferred method because it is a true SEALANT. Even though it also acts somewhat as a lubricant, you don't have to tighten the joint near as far as with some other method to get the joint to seal. The whole point is to tighten the joint only so far as you have to to stop the leak, AND NO FURTHER!
If it won't tighten up, cut it out and replace with a new one, But don't use glue on it, It will be there forever and you won't be able to take it apart later on. Use Teflon tape on connection and it won't leak
