Still havin problems finding the fuel pump relay, anyone know where it is? i got a 90 civic hatch 1.5L. Also do you have to drop the tank to change the fuel pump? or can you get to it through the access panel under the backseat? I was also wondering if a DSM turbo fuel pump would bolt on or will i have to do any mods? Also what is the difference between a stock fuel pump and the dsm turbo one? is $40 a cheap price for it?

 

You have to drop the tank.

The main relay is the fuel pump relay. It's located to the left of the fuse panel above the hood release. Instructions to locate it - http://www.crxsi.com/resources...elay/

I have heard about people putting in the DSM pump. Did you try search? If you have a stock 1.5 why on earth would you want to flood it with more fuel?

 

The relay is up under the dash above the clutch pedal its usally brown in color. It might be a little bit of a bitch to get it off of its mounting bracket but it will come off. And the fuel pump sucks on these cars you must drop the tank and its on the top. My friend actually cut a hole in his floor so he could acces it easier. I would say the try not to use to many DSM parts on your Honda its bad luck. lol
anyway good luck man.

the fuel pump only supplies the fuel. it will not flood the engine. hence the fuel pressure regulator and computer to control the injector pulses. the dsm pump will only make it possible to raise the fuel pressure higher than the stock pump would beable to handle. not incredibly higher, but it can sustain more action than the factory honda componet.

also dsm parts are not bad.

 

just get a fuel pressure regulator and you will be fine.
