echo string trimmer fuel hose is 'riddled like swiss cheese' & won't run (pic posted)

my echo string trimmer won't run for longer than ONE SECOND, no matter -what- I do. one (of the three) fuel lines is riddled with numerous pinholes - the pinholes only "squirt out sideways everywhere" when the primer bulb is pushed. might those tiny holes ALONE cause it to be unable to run longer than a second? not at all clear to me which fuel line serves what purpose on this machine. "otherwise all conditions are good to go" on the dern thing. baffling.
I posted a good clear captioned pic of this at

are these tiny black fuel lines 'off the roll' stuff at mower shops? or is this a 'proprietary deal' type thing?
thanks guys,
toolie

You can use 'generic' fuel line of the correct size, but it must be approved for fuel (or it will dissolve or start a fire).

I've bought fuel line both ways at repair shops. Not expensive. Your fuel line was likely destroyed by alky fuel (gasohol). That stuff eats fuel line for lunch! especially the older line. In Minnesota you can purchase non-alky fuel for hotrods,classic cars and small engines.I go through about 20 gallons a year for lawn and snow blowing equipment. Pricey stuff and hard to find at times but it beats repairing my equipment needlessly.
Good luck. H.R.
