my rpm and km's dont work, plus when I pump fuel, it bubbles up and splashes out.

my rpm and km's dont work, plus when I pump fuel, it bubbles up and splashes out.

for my rpm and km, they both either work or they both dont at the same time, electrical?

as well, I dont know what the problem is, air? but when I pump fuel right about at $3.00 the fuel pump stops, and the fuel sputters out, wait awhile and put more in, just have to go slow or else it keeps happening, what is wrong?

thanks
