Gas line routing

Unless your cylinder head is a '60-'62 item, remove the spark plug washer rings—they are not to be used with '63-'74 heads, and using them makes the plugs run hot, which increases the tendency to ping.

Also, today's Autolite spark plugs are Chinese junk. Don't know how a 4-cylinder '90 Dakota should figure into it (shouldn't), but swap 'em out for a set of NGK ZFR5N plugs (stock № 3459).

That plug number NGK ZFR5N is for a 1990 dodge dakota. The reason why I did this is because try and walk into an auto zone and ask for a plug with a part number. They will have no clue what you are talking about (at least around here). Hell you have to give the the engine size, is it a 4x4, what color is it for damm wiper blades. But if you give them the year make and model of the car and then ask for NGK you will not get that deer in the headlights look. Here is a screen shot to show you what it fits.
