Default itr fuel pump vs 91 si fuel pump? Differences and similarities?

I'm interested in the specs of each, as well as the dimensions.

Also, if anyone has used the itr fuel pump in their EF can you please post up your experiences?

Thanks!

As I understand, the ITR fuel pump uses a smaller case (similar to the Walbro pump). As such, it is possible to use. But fitment will be a challenge. If you want to use this pump, you might as well just buy a Walbro kit. It will be cheaper. And you will get a new pickup screen and hardware good for at least a so-so fit.

I totally agree with StorminMatt, as I've had an ITR fuel pump in my CRX before my current Walbro. The ITR fuel pump fits, but you need to lengthen the uptake hose so the pump will sit in the stock position on the bracket. I didn't do this the first time and I wondered why I ran out of gas when I hit 1/8 tank. My ITR pump eventually burned out and fortunately didn't cause any engine damage during racing. I installed a Walbro 255 (which I should have in the first place) and no more worries about fuel. Basically, if you are going to go thru the trouble of dropping the gas tank, might as well put something in there that will be more that sufficient for your current/future needs.

Thanks guys.

What about the flow rate of each? I assume the voltage is the same for both then as well.....?

I too installed an ITR FP in my 91 Si hb. Its getting old having to fill up at 1/4 tank. I noticed no REAL difference performance wise. I just did it cuz I got it for free and the old FP had 200k plus on it. Hopefully one day I will mod the FP to sit lower in the tank so I can actually use all 12 gallons of gas. HTH

I cant recall specs for the ITR Fp but the civics are all 70lph. I wanna say the ITR and gsr FP's are 120lph but I may be wrong.

Yeah, no ****! Can anyone confirm?

As for that theory though, wouldn't the stock fpr keep the pressure the same - regardless of the fact that the fuel pump is pushing less?
