05COLEGGT Posted June 2, 2011 Share Posted June 2, 2011 Anyone know what the stock fuel pump flow rate is? I searched and couldn't find this information. Link to comment Share on other sites More sharing options...
Leviathan Posted June 4, 2011 Share Posted June 4, 2011 I know that some parts stores have fuel pump books you can look up part numbers with flow rates on them. You could give that a try. Link to comment Share on other sites More sharing options...
fahr_side Posted June 6, 2011 Share Posted June 6, 2011 Anyone know what the stock fuel pump flow rate is? I searched and couldn't find this information. To the best of my knowledge it's 155lph. The '08~ STi item drops straight in and does 175lph. Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.

05COLEGGT Posted June 6, 2011 Author Share Posted June 6, 2011 Good to know. I may have another alternative for direct fit. A BOSCH 190lph for a Ford Lightening pickup. All I need is the length of the OE fuel pump to know for sure. Not sure I want to hassle with a walbro loudass 255lph when I don't need that much flow.

Maybe if you specify which points you want measured I can help. Do you have a photo of the pump in hand to mark the lengths to measure?

05COLEGGT Posted June 8, 2011 Author Share Posted June 8, 2011 I do have one of these pumps. It came from my previous project car. The length from the tip of the inlet to tip of outlet is 4 3/8". Link to comment Share on other sites More sharing options...
fahr_side Posted June 9, 2011 Share Posted June 9, 2011 My old WRX pump, same fitment as the LGT, is 111.6mm (4.394") tip to tip.

05COLEGGT Posted June 9, 2011 Author Share Posted June 9, 2011 Hmm...I'll have to measure it again, but doing the conversion it looks like this Bosch 190LPH is pretty much a direct drop in, no modifications required. :-) This pump easily supported 400whp on my old car so it should do just fine for my Leggy.. Oh and it was nice and quiet.. Link to comment Share on other sites More sharing options...

Oh and it was nice and quiet.. These pumps are different to previous generations in that they have two plastic clips molded into the top cap which snap into the bucket (surge tank). There are photos around the place. If those aren't there on the new pump, and they are missing on the Walbro, the pump can be jammed up against the output o-ring by the tight fit inside the bucket. So, as a rough idea, your pump wants to either have these clips, or be the same length as the Walbro in order to work like this. There are a bunch of threads on Walbro fitments, DIY walkthroughs etc. Suggest you scan these before deciding how to proceed. But having said that, if this works you'd be pioneering something pretty useful.

RUMBLGT Posted February 25, 2018 Share Posted February 25, 2018 I know it’s been years. But I just found this. Did you ever try the Bosch pump 05COLEGGT? Link to comment Share on other sites More sharing options...
