I just bought a walbro fuel pump 255. I think it was for an EG. Think it would still fit on my 90 civic EF hatch? And Do I have to drop the tank to replace the fuel pump on the EF cause I took my backseat out and couldnt find the actual fuel pump.

 

Yeah, you'll need to lower the tank.

Do a search, I just posted a DIY a couple days ago.

 

So is the honda fuel pump universal? Will the EG fuel pump fit the EF?

 

fairly universal yes, take the stock one out and give a quick visual comparison, you'll see that you can slip the other one into the carriage and tighten it down.
