In the process of installing a new front O2 sensor on the passenger side, I broke one of those small bore SAI vacuum lines. I used a small piece of equal diameter fuel line to splice the lines together. In looking at replace the whole line I managed to crack the line from the throttle body to the expansion tank. Again using fuel line I splice the two pieces together. I get that the car is old '04, but who in the hell thought plastic was a good idea?
Do owners just sigh and order a new one or do they go down to AZ, NAPA and get something more flexible as a replacement?

 

Broke the line from the radiator to the expansion tank, then to the throttle body. Used fuel line until I wanted it back to original and spent the $30 or whatever on replacement lines that were OEM.

Probably find it cheaper somewhere.

 

Ab has a genuine for $43 and an after market for $20. I am really considering if it would be better to replace as they get so brittle over time. Not a big deal to have a some extra in the back of the car, cut and go.

 

The PO had substituted fuel line on the reservoir to expansion tank, and it blew on me. I replaced it with transmission cooling hose, until I got the OEM replacement. If you use fuel line, i would recommend keeping a spare, luckily i was 2 blocks from Advance Auto.

 

Much less expensive that metal and still ridged requiring less standoffs than hoses. Good time saver during mfg. and routine mx. Vacuum lines are easily replaced with less expensive vacuum hose of same diameter. Hose will not usually become brittle/break but will deteriorate over time as well. When my time comes around will replace vac lines with hose. Already have done temp repair on the coolant pipe using fuel line will probably change that out with proper sized heater hose that's about $25 for 50'. These are not new vehicles and do require a thorough going over to avoid constant annoyances.

These brittle lines are absolutely notorious. Plastics are engineered to be pretty damn durable these days, but 12+ years of engine heat and it's not surprising they go kaput. I've replaced them with genuine parts. A lot of people replace them with fuel line, which apparently has caused trouble in some cases. Just thinking out loud here, but I wonder if it would work to replace them with brake line bent to the same shape as the original.

 

after 14 years i figure a hose set was the easy way out, not the cheapest.
if you catch AB on sale they are not so bad

 

drowssap- I was thinking the exact same thing myself, I bought the non OEM throttle to expansion tank hose from AB yesterday. It's a little cold here to start pulling all the hoses so I think the full set is on my spring maintenance list.

 

that little hoses i slid pieces of fuel line over any where i thought it may rub in the future.
