I had to swap out my d16y8 73lph pump for another one. The only one I had was a 1995esi talon non-turbo pump. I know my fuel pressure is dead on, but I dont think its flowing enough. How do we find out? is there a formula?

Ive searched the denso part number for weeks, and couldnt find anything.

 

anybody?

 

I believe it is about 180lph... I know when I needed a replacement I just bought a walbro 190lph and from the research I did at the time, I wanna say it was roughly 10lph more than stock. Stock (which was also walbro) from the dealer was roughly $350 and I got my walbro 190lph for about $80 which I was flamed at the time that I even spent too much on that and that I could have gotten it for about $50. So there ya go!

This is the one I got but it looks as though it's gone up in price a bit since I bought mine about 3 years ago:

It says it's a Holley fuel pump but when you get it, it's just a rebadged Walbro.

 

and was this an OEM one for a talon ESI?

 

No, it was the bad OEM one for an aftermarket OEM replacement. I guess what I was getting at was I don't think your stock fuel pump was 73lph... That seems extremely low compared to my personal experience. I really have no idea what the lph is for a talon ESI pump. To be sure your pump is providing enough fuel I would recommend just buying an OEM replacement as the can be had for fairly cheap and you can eliminate the possibility that you're not pumping enough fuel.

 

1. Disconnect your fuel line from the fuel rail and put it in a bucket.

2. Hot wire the fuel pump to run constantly - it takes 12V.

3. Run the pump for 1 minute. Calculate the volume of gasoline (in liters) pumped in that 1 minute.

4. Multiply by 60 - now you have LPH (liters per hour)!

 

nice to know, wonderfull answer thank you
