[:@]i bought one with a bad fuel pump.....its not an easy job! i got about half way there today but ran out of daylight so i hope to finish it tomarrow or it might have to wait until monday.
Anyway it is a 1990 Iroc Z...5.7Litre...245 hp...345ft.lbs.....K&N filter(s)...THe guy i bought it from said its got a mild cam, Yank Yank, ill believe that when me **** turns purple and smells like rainbow sherbert...lol! Here are a couple pics i will post more 2mro when it is daylight i am having some troubles with the pump job b/c i am doing it the right way droping the rearend not hacking it up...Maybe someone can help... i got the exhaust, sway bar, and the two bars that run from the drivers side bolted to the bottom of the car to the passenger side bolted to a bracket then another one that runs back to the drivers side kindof making a < anyone follow?....they are off and alsoall the heat shields are off but now my directions say to unhook the gas lines befor i drop the tank and i cannot find where to unhook them at...Avid mechanic full time driver so this is about the biggest job i have ever attempted by myself! Also there is a long bar that lookls kindof like pre assembled roof joyces or something runs paralell to the drive shaft the entire length of the driveshaft what is this called and do i need to unattach it to lower the rearend where it needs to go to wrestle that tank out of there? Best thing about the car i only got 1500 us dollars in it! Let me know what you think!

 

That long bar that runs along the drive shaft is the torque arm. You will want to unbolt that from the rear end. You will want to unbolt everything from the rear except the brake line and control arms. The drive shaft can stay also. Unbolt the shocks, sway bar end links, pan hard rod and torque arm. You will notive the rear will pivot when the torque arm is unbolted, thats why its there.Jack the body as high as you can. The rear end needs to drop as far as the brake hose will allow it. Leave the control arms bolted up.
Look for the fuel filter. Its near the left rear wheel. Its right there with the other fuel lines you need to disconect.

 

When I did mine, I didn't need to unbolt the torque arm, I had enough give. You also need to remove your right spring, but it will fall right out by the time you have everything dropped anyway. The right side of the tank drops first and you rock and roll it out to the right beyond where the spring was (which is why you need to remove it). It's not a hard job, just time consuming.
