Elkidmino Posted August 12, 2008 Report Share Posted August 12, 2008 (edited) I've had access to a fuel pump test bench so I went ahead and ran these pumps to get some numbers. All pumps are new out of box when they arrived. Yes, that is an OEM Mitsu Starion pump with brackets, dampener and all. If the attachment doesn't work, I'll get screenshots later. Also, I'll update this post with hard numbers later today. Supplier's Chart of Walbro FLow http://www.26liter.us/gallery/albums/userpics/10121/GSL391-specs.jpg The number's I flowed: kPa vs Lph http://www.26liter.us/gallery/albums/userpics/10121/xcel_flow_numbers_kPa.JPG Psi vs Gph http://www.26liter.us/gallery/albums/userpics/10121/xcel_flow_numbers_Gph.JPG Well, looks like I'll have to do this the hard way.

Komeuppance Posted August 15, 2008 Report Share Posted August 15, 2008 Good info. I thought the pumps spec'd for the Starion are gsl392...?? Your standard walbro 255 pump, same as the 391 right?? How about a chart with PSI vs L/h?? (On your second chart, you forgot to change Kpa to PSI) -Robert Link to comment Share on other sites More sharing options...

Shelby Posted August 18, 2008 Report Share Posted August 18, 2008 how about throwing a bosh high end pump chart in with the walbro pumps i notice all the pumps start to fall off arround 75-80 psi,, the CIS bosh runs 80 psi 24/7 , but on the down side the high volume bosh may over run most of the std pressure regs with small fuel lines , most applications use 10 mm id fuel lines not 7.5 mm id line Link to comment Share on other sites More sharing options...
