Dirty Ditch Dawg

well, after working on my recessed Led lights,
i rememberd my son mentioning a gas smell a few weeks ago when i had
all the windows out, and the other day when walking around the jeep
when the bottom back plastic corners off,

so i checked the Rollover check valve,
this morning, its shot all crumbly rubber,
,
so i read alot of the back posts, (90YJ by the way)
and did what one of the posts said,
i took the doo-hickie and went to the auto parts store,
and told them i needed another one,

they all,,three of them looked at it, and went into shock,,,
what is it?,,,whats it do? where did it come from?
why does it smell like gas?
,
i knew i was doomed,,,its beutifull out, and im jeepless,
till tuesday,,,GRRRRRR
till the jep dealer opens up,
,
but i was wondering if i can temperarily re-route any hoses back there
to be able to drive this thing,
i have the small hose stuffed inside a large hose, that fits over the
steel fuel line, with clamps,

IS this safe? im not looking for a darwin award.
