For $100, you're going to be highly disappointed. I just checked Rock Auto.
First off, you're going to have to either do some more research on the part so you can be sure that you get the right part, or remove the old part so you can identify the right part before you purchase it. You might even need a special tool to remove the fuel pump.
Now if you're lucky and you have the fuel pump assembly with the metal rods holding it together, then you can get the cheap Airtrex fuel pump kit from Rock Auto. You can also get our 5% discount if you get the discount code from our Vendor Deals, Group Buys, and Special discounts forum.
You will need to ask or need to figure out which one you have. According to Rock Auto there are at least 3 from what I understand.
