Yesterday one of the small hoses on my 1993 5.0L XLT developed a pinhole leak. I'm pretty sure I have replaced this hose a couple of times. I looks like a 5/8" heater hose. Does anyone know if there is a specific replacement hose for this or is it just a section of heater hose? Initially I thought it might be the by-pass hose but I think that is a different hose. I have attached a couple of pictures. One shows the hose with the leak and in the other picture you can see both hoses.



Hose I need to replace.



I wrapped some electrical tape around the leak so I could make it home. Just barely made it. You can also see what I believe is called the bypass hose?

 

The bypass hose is the newer one shown coming off the pump. I would get a proper diameter heater hose, cut it to length and bend it before connecting.

 

Thanks Raski. That makes sense.
