I need to know the fuel supply PSI and GPH rating for the EA82 single port fuel injection throttle body.

 

Because of my custom application, I can't use stock or direct replacement fuel pump, so please don't point me to any replacement units that "should work".

 

I'm only asking for the fuel supply requirements (PSI and GPH) please.

 

Thanks!

Well I have direct experience with using the 80's Ford F150 frame rail mounted high pressure pumps and they work just fine.

 

To a large extent it doesn't matter so long as you don't get a pump that's produces vastly too much pressure... which is unlikely since virtually all automotive (port/throttle body) injecton systems are 43.5 psi or in the specific case of Ford - 39.15 psi..... the F150 pumps put out 50 psi if you dead head them. Which is what the SPFI pumps do. The F150 pump has a similar outlet size to the SPFI inlet which means it's going to flow similar.

 

At any rate they work fine. Go with that.

A member of the Samba VW forums was familiar with the conversion and directed me right to the Subaru manuals.

 

Section 2-8:

Pressure capability 36-50 psi

Flow rate 21gph @ 21psi

 

For the benefit of others, the Carter P5000 is the best match (to retain the correct plug for the aftermarket ECU):

Carter P5000: 45gph@45psi

For the benefit of others... at the time of this posting, I didn't realize that my EA81 had a GM SPFI throttle body.  So the specs I needed were actually for the GM TBI which we were able to lookup from casting codes.  I have two other posts that ask independent but related questions to why I have a GM SPFI on my EA81.

Thanks all!
