You can't move the venting. You have to open the cap which vents the tank completely.
Speaking of static. Fuel hose has to be to standards to avoid this. I replaced the fuel hose on one of my overhead diesel tanks. The new hose was rated correctly with writing all over it. After a couple of years of use it started to crackle as the diesel ran through it! I had heard of it happening but thought it was a load of crap. But... It isn't. The crackling is static build up in the hose from the fuel running through it.
