Re: New to me 68 250
I was able to pump out the fuel in the lines because the vehicle had an electric pump in the tank. After replacing the tank pump, and reinstalling the tank, it was as easy as turning on the key with the lines disconnected and pointing into a jug.
You your car, it depends on how much is in the tank. It will take a LOT of cranking the engine over to get all the fuel out if you have much in there, because you only have a mechanical pump on the engine. There is no pump in the tank. I only used that method on that vehicle because it had the electric pump in the tank.
I have a hand crank pump hooked up to a 20 gallon barrell. As stated, hard to get rid of. Most larger cities have drop off for hazardous waste. In OKC there is no charge for residents of the City.
I have also used a small electric pump. Either way, be careful. This stuff is volitile.
If you want something close to the original tire size, a 205 75 R14 will work. Kind of skinny by today's standards. That tire would be 26.1 inches (in theory.... in practice, they are close, but never spot on as the first and second numbers are "approximations" and not dead on). They also vary by manufacturer. Still, 26.1 is very close to what a 205 75 R14 will be.
Even with 14 x 6 wheels, you could run a 70 series tire and not be in danger of rubbing. You have two choices: 215 70 R 14 is 25.85 inches tall, so 1/4 inch shorter than your current tires, but wider by 10 mm (between 3.8 and 7/16 of an inch). If you go one size larger, to 225 70 R 14, the tires are 26.4 inches tall, so about 3/10 of an inch taller. I am pretty sure you can find guys running that size tire without issue.
Good luck and have fun. I always wanted to build a 250 six with FI and a turbo.
BTW, your profile isn't filled out. In what part of the Country (or world) are you?
Also, on tire sizes, it is very easy to calculate the approximate height. I memorized the formula about 30 years ago, and refer to it often.
That first number is section width in mm, NOT inches (not necessarily tread width, but the width of the tire at its widest spot). The second number is the aspect ratio. The smaller the number the shorter the tire is in relation to section width. The R just stands for radial. The last number is wheel size.
Formula is (S x A x 2) divided by 25.4 plus W.
S = Section Width
A = aspect ratio (and remember 70 = 70%, so you use .70 for 70 series tires, and .60 for 60 series, etc.
2 = well, 2
you divide by 25.4 because there are 25.4 mm to one inch. The section width is expressed in mm, so you must convert.
