A less expensive alternative is to buy a universal fit spiral hose in the same
length as the lower hose and remove the spring from it, then wind into the new
lower hose. Done.

Subject: [Tigers] Lower Hose Spring is Required
This is a repeat of a tech tip is send in about a year and a half ago.
A spring in the lower hose is defiantly required. If a car suddenly
overheats as the rpm goes up with vehicle speed, the problem is probably
caused
by the collapsing of the lower hose when the pump inlet pressure goes
negative.
For some reason, some hose suppliers have quit supplying the springs in
lower hoses, probably some low cost un-American supplier. I found that a
"Rainbird/Toro" impulse lawn sprinkler has a stainless spring that works
great. The spring can be twisted if necessary to make it tight. You can buy a
sprinkler head for about $16.00 and it's worth it just to find a stainless
spring.
