Hey Kim==You might try a different brand of pumps. GoodluckJoe
are there 2 fuel pumps on a 1984 chevy citation
yes
No, just one.
Yes, They are a different size.
2 a primary and a secondary
All small block oil pumps will physically interchange with each other, before 2000. Keep in mind they make high pressure, and high volume pumps, as well. They are usually just big block pumps. Yeah, they are all the same.
No, There is only one and it is inside of the fuel tank.
Up to late 1986 yes. After that year no.
fuel pumps whine when they are going bad
By that time Chevy was pretty much using electric pumps that are located in the tank, itself.
yes it does it has one on the top and one the bottom
Assuming this is a gas engine with one fuel tank, one.
