i am doing an lt1 swap in my 87 lg4 z28. i need to replace the gas tank and pump. when i went to the parts store i had 2 choices. 14 or 15 gallon tank. which do i get. also i believe on came with a filler neck and the other without.i need to know so i can get it ordered. thank you

 

anybody?

 

If they all fit the same way.. its all up to you.
Id get the biggest one.
The stock one is 15.5 gallons, so ..

 

but do they all fit the same way?

 

Im sorry, I dont know.. they shoud have
the specs at the store.. theyll tell u..
But i mean the stock size is 15,5 gallons..
why change it ?
(maybe im wrong)

Good luck

 

I read around on these board, that the 4th gen tank is good as it is a direct fit and it is lighter (plastic?) and I believe is still a good 15.5-16 gallon tank.

Should look into that.

 

Yup... its plasitc.. ligther..
Id get that..

 

i've heard that it doesn't fit in a 3rd gen. if it does somebody give me some affirmation on it. i already have a 4th gen tank and pump. that would save me about $250 if i could use the 4th gen one
