how to upgrade a 93 1.8 fuel pump?

Jaxx · 05-26-2003, 12:04 AM

howdy

so i went to change my 1.8 fuel pump to a nice used WRX one ...

the 1.8 pump is huge ... and not even close to the same size as the WRX pump and they are not interchangable not even close

any ideas .. i don't want to go to the junk yard

.. but that may be the only way

no
the diamater and length are both differnt and the pickup sock up won't connect ..

I think the best way to do it is fabricate a jumper. The jumper would have the male clip that slides into the pump on one end and a smaller male clip that slides into the recepticle(sp?) on the tank access panel on the other end.

As for where to find these clips, I'm not too sure. I was able to find one pre-made. Good luck.

go to the Junk yard and find '92+Civic or '90+ Integra and pull out the rear seat. You will find an access cover in the center where the fuel pump is. You will need to cut the connector to use on your new fuel pump and you can also use the tubing and filter bag from it as well. There are other cars that use the same connector but they are harder to access.

You will have to splice in the new connector to your existing wiring and change out the tubing as well as fit the filter bag onto your new pump. As for securing it, I ziptied my fuel pump against the metal bracket.

What year did Subaru switch to the compatible fuel pickup/wiring etc?
