Hey Eb,
I think your asking if what they gave you at Napa goes in your existing fuel filter housing. Its hard to say without seeing them both. I would say just shut off gas, pull filter and see if it comes apart. If you cant figure it out just take it with you when you go for a replacement. Get something east to replace and readily available. Good luck,
Jeff
