I bought an Holley (Walbro) fuel pump and I thought it was an 255lph, but I looked at the side and it says typical flow 120lph@300kPa. Did I get giped or what? On the box it says New Forced Induction Design. Part number12-916. I looked it up on Holley's web page but it wasn't there. Can anyone please help. Thanks

 

fuel pump delivery rate is advertised and rated according to the output LPH/GPH at a given fuel pressure setting EX: 255LPH at 45 PSI. Holley makes 2 different 255LPH pump the other one is designed for forced induction use. and to verify that you may/may not have a problem you have to call Holley Tech Support Dept and have the F/P part # handy

 

I got the same pump and if i remember correctly the test was on a Mustang so I doubt it is the same pump. I just put it in and it seems to have solved the problem I had. I was running a JR pump and it was getting lean at 6K.

 

I wouldnt trust any walbro pump on a turbo car. It would have to be the bosch pump. Ive seen 2 walbro pumps that were not able to keep up with the high fuel pressure that we get by using an fmu. I assume you are using a FMU. If not then the walbro will be ok...
