Laparoscopic fuel vent hose repair without dropping tank

[PeteB]

I did watch your video already Robert.
Tested the fuel pump cover this morning and it did not leak, added half a gallon
of gas, still no leak. Added another half gallon and the vent hose leaked, have
a new one now that I'll put in.

Did the hose today and it took a few hours. I tried to estimate the correct spot to drill,
made a 1/2" hole and it was pretty far off, used a nibbler to open it up in the
corner where I could see the hose clamp screw about another 1/2". It was soft
and very easy to cut away. I'm not sure if the short vent hose vs. long makes any
difference on the correct location of the hole. I'm not worried since I was ready to
make a 1" hole if needed.

One hose clamp was rusted, used some PB Blaster,
let it soak in, it took a 7mm socket and I was able to use a 1/4" drive to break it free.
There were two wires the pair to the level sensor and I think another to the roll over
sensor, pushed them up and away from the nipple. Was able to pull off the end near
the fuel pump fairly easily with vice grips on the hose, then pulled the other end and
pushed with a screwdriver.
I opened the end of the new hose with a socket as suggested by cn90, greased them
and finally used some oil on the large end that is difficult to get on. Put it on without
the hose clamp, then open it all the way to slide it on. I put the large end on first, I
thought I read to do the other first but this was easier in my opinion. Reach in from the
small cover plate hole to guide the hose on, doing it mostly by feel and looking into the
access hole works.

Still have to, top it all the way up and see what happens but it looks good so far.

Just for the record, the rollover valve doesn't have any wiring etc. It's just a mechanical valve that works on gravity - turn it upside down and it blocks fuel flow.

Hope you have it fixed!

Filled up today - no leaks, calling it good, thanks everyone!

I covered the whole with a cutout from some aluminum flashing and
was going to use short sheet metal screws to hold it in but worried
that the screw points might puncture a vent hose or electrical connection.
I covered the aluminum flashing with some very sticky duct tape - lazy.
