I have a 1996 honda civic hatchback dx and i need to change my fuel pump. Should i go with an oem or aftermarket one? I already verified that its the fuel pump and not a fuse or relay or any other problem, and i am leaving the car completely stock performance wise with no upgrades

 

if it's a pump running the same specs I dont think it would matter if its OEM or aftermarket. But I do believe that if u go with a bigger aftermarket pump like I did from a stock del sol one to a Walboro 250 I believe ud need a tune or u could be running extra rich. I could just be mixing up fuel pumps with injectors.

 

You should be OK either way. If you go aftermarket, get something comparably sized to OEM, like a Walbro 190.
