87z 350tpi tach and fuel gage, gas tank wrong
After the transplant to the built 350, the tach is off, is not right,
Its seems to show way more rpms. its worse with the higher the revs go.
Bad ground under the hood some where??? or do I have to change some module for the old 305 to a 350 to get it to be correct?????
The fuel gage shows 1/2 tank when empty other than that its ok.
bad ground???
Most all gages peg to the positive when I start the car, then drop off to what looks correct, volts, temp .
what do you think??
Maybe several different problems??
Also I ran the gas tank dry tonight oopps , I noticed the fuel pump was making funny noises.
I opened the gas cap and hot fumes came out, felt that tank and it was really hot as well.
I kept putting the gas cap back on and taking it off and still hot fumes still coming out, kind of scary.
How about this one any ideas? Bad ground? hot fuel pump??? hot wires? I did notice the muffler is about an inch way from the bottom of the tank. Man I don't like that either.
thanks

is there a heat shield between the muffler and the gas tank if not do not drive the car there should also be a shield where the pipe goes over the rear end if these are not present
