Are the fuel pumps diff. from EG?

I see these articles with people who have bling civics and integras.....they say under mods: ITR fuel pump

I looked in my shop manual, no info on different fuel pumps.

Thanks for help.

 

Andy, have you checked Len's site and compared PN's? I'm curious of this one as well.

 

Here are part #s


94 GSR 17040-ST7-A31

00 ITR 17040-ST7-L31
00 LS 17040-ST7-L01

99 SI 17040-S01-A40
99 EX 17040-S02-L01

 

So, the CX fuel pump in the EG is not for Vtec.....thus. me needing to change fuel pumps.

I see the numbers are different, but is that different years or body styles?

 

only way to really know if the different part #'s really mean anything is to flow test the different pumps.

 

I am presuming that flow rates are different amongst the various integra and civic models.

 

I used a 00 SI pump in my 92 vx hatch along time ago. Hatch had the si motor also.

 

sohc non-vtec,sohc vtec,and dohc non-vtec fuel pumps flow 79lph.
dohc vtec fuel pumps flow 134lph..I have an 89 crx and with the stock fuel pump it was running lean in the upper rev range with the B16a motor..I found this out using a wideband o2,,,Put in a gsr fuel pump and it runs better now..

Don't the integra fuel pumps fit differently compared to ef ones?

 

it was my understanding that the ITR fuel pump has a higher flow rate than the GSR/Civic Si.. is this incorrect?

 

I ran an ITR fuel pump in EG when it was boosted. I don't remember the flow rate, but it was the highest of OEM pumps when I bought it in '98.

Yeah they fit alittle different..I kind of rigged it up alittle bit with zip-ties to the bracket and little rubber pieces to get it to sit like the stock fuel pump,,and re-used the stock strainer..And I think they guy with me soldered on diffferent connectors..I forget though,it was a while ago..

 

So the flow rates are different between Vtec Bseries vs. Single cams<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by Mr.speaker &raquo;</TD></TR><TR><TD CLASS="quote">sohc non-vtec,sohc vtec,and dohc non-vtec fuel pumps flow 79lph.

Is the part number on the fuel pump to tell if it is from a ITR?
