I've tried a cap that was listed as being for a Tiger on Autozone's website but I think the pressure spring part under the cap is too short. I almost immediately start getting water out of the overflow tube as the engine warms up. I measured the depth of the expansion tank opening from the top edge to the flange where the spring part of the cap would sit and got .777". I measured the cap from the big rubber seal just under the cap to the small rubber seal at the end of the spring and got something like .75". So it looks like I need a cap with a longer spring stem. <o:p></o:p></p></div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'> <o:p></o:p></p></div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>A brand name and part number would be great.
