To completely satisfy myself regarding the higher-pressure of the Airtex E2000 fuel pump commonly used with a DIYS (DoItYourSelf for any who don't know) TBI system, I did a free-flow test using a brand new pump. Here is what I did and found:

I connected a 5/16" steel line/rubber hose to the inlet (tank) side of the pump. Then, I connected another 5/16" hose, with a wide-sweep 15 lb. gauge T'ed ino the line which was then reduced into a 1/4" steel line/rubber hose returning to the tank.

With full power (12v) to the pump it registered less than a half pound pressure free-flowing (unrestricted) through the lines. As a result I no longer have any questions, concerns or doubts regarding the use of this higher pressure pump. Another good thing... E2000s are in-store shelf items at almost any auto parts store... nice to know if you need a replacement.

If this helps anyone... GREAT!... if not, that's OK, it helped me. :cool:

Good info Don,

I run the same pump with my LS motor, even running it as a puller on the frame, instead of a pusher in the tank, so far so good
 
Josh, I used the E2000 pump as an in-line (puller) on Granny 2 and it worked great. Now I am in the process of doing the same thing to my little CJ-5, but with a 5/16" supply and 1/4" return I had some concerns as to how the pressure would work out with smaller diameter fuel lines. The E2000 pressure range of 70-95 psi is considerably higher than the 12-13 psi the TBI requires. Now that I know it's not going to blow up on me I can relax. :)
 
I use this on my tbi system.


Any body know if this pump will handle diesel fuel?
 
With a diesel application, I would be more worried about flow than pressure. Although, both very are important.
 
It's not for an engine, it's for spray down. The flojet transfer pumps are shit, flojet is no better.
 
Ahh, gotcha. Carry on :D
 
Another interesting tidbit of info: I was curious regarding the current draw and wire size requirement for the E2000 so I called Airtex support. The man I spoke with told me the E2000 was capable of pulling about 7 amps so a 16 gauge wire should work just fine. Personally, I wouldnt use anything smaller as 18 gauge maxes out at about 7 amps.
