I had this exact experience.

 

i was about to buy a pump for my 5.3 and have always ran e 2000s but i think i am also going to switch to that pump!

 

I found 50 horsepower, easier starting and better durability in the 8248 as well. Went through two e2000's in a few months, now the 8248 has been in there for almost a year without a problem. I highly recommend this pump too.....

 

Great info- I am sick of my e-2000 problems, next pump is gonna be one of those.

 

Yep, same here.
I got the info from Woodlee several years ago and never looked back!:smokin:

 

are there any specs on this pump? Autozone does not show any flow or pressure ratings.

 

use the google

Airtex # E8248 Elec Fuel pumps are available through most auto parts stores.

This is an INLINE (not in-tank) rollervane pump for high-performance applications with Multi-Port fuel injection. ...It can be mounted in any position. The pump is supplied with two wrap-around cushioned mounting brackets. ...The inlet & outlet connections are barbed fittings to accept 3/8" fuel hose. (Be sure to use EFI hose rated for high pressure systems!)

Specs as follows:

12 volt - negative ground
60-70 gph max
110-120 psi shut-off
7-3/4" long x 1-7/8" dia

Flow at nominal fuel system pressure of 36psi is approx 45gph drawing 8amps at 12vdc

This pump is suitable for use with leaded gas, unleaded gas, or gasohols.

You should install a suitable strainer between the tank and pump. ...A METAL hi-pressure filter should be installed between the pump and engine.

E2000 flow 30-40GPH at 70-95 PSI

Look it up on advanced auto, it has the specs.

 

great info....I am prolly going to switch mine out this winter.

 

Rob does this pump have threaded fittings on each end that could be adapted to AN?

 

Mine didn't come with the correct AN fittings. I got them from Gary/Greg(can't remember but it is one of the 2). He built my entire fuel setup and it was all plug and play.

This is the pressure side. The silver fitting is exactly like what is on my fuel rail. They are GM O-ring fittings adapted to AN. The bronze colored fitting screwed into the pump came with the pump. (For information-The pump pictured was my E2000. But both fittings were exactly the same from the E2000 -> E8248. It made swapping pumps simple).

 

just checked out purechoice andf they seem to have the fittings, ect that i'm gonna need for our next swap:shaking:
87 wrangler with a 94 4.3 vortec.

and BTW summit has fuel rail adapters that screw into the back of the fuel rail to -6 male for under $20 for the pair.
thanks for some more info

 

are any of you running this pump with the 4.0L?

 

I wasnt aware if this pump until a few days ago. I'm running an E2000 with my 4.0L YJ and wondering if swapping over would be worth it, I havent noticed any performance drop but its been in there since my 60s and big tires went in...

 

What were the causes of all ya`lls E2000 pump failures?

Sucking up junk in them ?
Hot fuel ?

 

Running low on fuel and letting them suck air. If they run dry very long they are toast.

 

Did you use quick disconnect to -AN adapter on the pump side? What part number is that? Thx

Danny

 

for short run times those pumps work great. but DO NOT last in high heat, or extended running in high heat. Burnt s few of them up in the V2R, along with several E2000's also.

 

You still using these or did you swap to something else?

And was it the air temp 'heat' or the fuel temp heat issue?

 

better than an e2000 on a 3rz 4 cyl tacoma engine???

3rz requires 36 constant psi...

 

How is the price variance from the e2000?

 

About the same price, $90-100 (see OP 1st post). I think Summit might have them for $5 cheaper too.

I'm running the e2000 on a Jeepspeed 4.0L and it has been working fine for 2 years. I'd say under extreme racing conditions, these pumps should be replaced after one year. The breakdown of foam and rubber bits in my tank is taking a toll on filter and pump.

Our race in Barstow this year was warm. I think racing temps were 112 degrees over about a 4 hour time frame. Felt the fuel cell afterwards and it was very warm from ambient temp. No problems with fuel delivery and pressure (40-45psi on the fuel pressure guage).

 

Gotcha.

 

Todd,

Aeromotive sells the -8 fitting you are looking for. -6 is asking for trouble feeding any sort of hp engine. You need -8 in and -6 out .....as a guideline.....depends on many factors suchs as hose lengths, location, pickups, filters and flows.

Building a fuel system that properly addresses the demands of a u4 style rig is fairly complex.

 

My tank is a custom piece and the person that built it put an AN-6 on the outlet. My prefilter is an AN-6 (Earl's part number 230206, 85 micron) inlet and outlet. I know the OE setup was an intank pump and a 3/8 inlet to the only one filter in the system and a 5/16 to the fuel rail. So, I think it is the similar flow as the OE setup.

I have a fuel pressure guage after the pump and it is only showing a 35 PSI to the rail. Maybe the pump is going out? But I would think a better flowing pump would help.

That's a nice pump and all, but damn......650 bux?!? Lol

 

I'm running 2 Walbro GSL 392 pumps. One primary and a secondairy backup plumbed in with a 3 way toggle switch.
To keep these pumps alive, I'm feeding them with 2 Faucet "feed pumps" pulling through 2 walbro pickups. The feed pumps will both run at the same time using 2 seperate circuits.
The feed pumps will go into an accumulator and the high pressure pumps will pull from that.
Like Camo says, Complex.

 

That sounds like an interesting setup....

 

No, I went the swagelok route.

There is a built in check valve in the stem, which I had to cut off to put on the swage fitting. I hope this doesn't have an effect on starting.

 

Guess I`ll be doing that
