Charlie, who did you order that pump from (I'm assuming ZZP?), did you need to replace that corrugated hose, and what brand gasket/lock ring did you get from RockAuto? I'm looking at the Dorman one (Part #579054). Any other tips/tricks I need to know before I pull the plug and order everything?

The AEM E85? I think I got it off Amazon. No, definitely use the corrugated hose. It's a surprising easy install.

Not sure what brand but def get that lock ring and gasket.

if you havent pulled your pump before, the current condition of your lock ring will be a present you will unwrap. Hopefully you get a good one and not a headache like mine was.

Would you mind pulling up your orders please? Amazon shows 3 different E85 pumps (1200, 1205, and 1210).

According to RockAuto this one comes with the O ring. Hopefully it will even though I ordered from Amazon...

Nice! I followed this http://www.intense-racing.com/walbroinstall.shtml and it worked perfectly. Prying the nippled out of the old pump sucks but I wouldnt have known to do that if it werent for that write up.

I have had 0 issues so far, even before I replaced my fuel filter. I didnt chop it in half to see what was inside but I wish I wouldve..

I took everything out in preparation for when the rest of the parts come on Monday. Problem is I don't have that center line like everyone else does. What do?



EDIT:

What does this little black wire go to? The instructions acknowledge it and say not to cut it off, but don't say what to attach it to (if anything).

I didnt have center line either. No idea about it.

Not sure about black line on pump either. maybe a remote switch or something?

I take it yours didn't have that line on the pump?

After a bit of searching I found somebody else who contacted AEM and they said to just let it dangle... Weird.

Got mine done today. Install went pretty straightforward, no major issues. My lock ring took a bit of persuasion to come off, but it only took around 15 minutes. Car starts and runs smooth, going to double check my fuel trims and adjust accordingly.

So my car doesn't like to idle unless it's been running for awhile. I bumped up the timing and idle RPM which made no difference at all. On a fresh start it will die down to about 500 RPM for a second or two and then stall altogether. After it's been running/driven for a little while it will idle just fine, no problems. If I just give it a little gas and hold it the idle will raise and hold steady, and normal/hard driving is just fine. Fuel trims aren't perfect but it has idled better with worse. Voltage is about 13.5 during normal driving and idling which seems low to me, drops into the 11s/12s when the idle drops to 500 and it dies. Ideas? I'm thinking of trying the voltage booster mod...

Edit: Pulled out my IAC and found this:





Slapped in a new one and it's all better now.

Just get a new pump. It's a little more expensive but it's a job you only want to do once and have it done right.

Ya I am sending ractronix an email that hopefully I can get it done this weekend and I can go back to driving it and run it down the track in 2 weeks and see what the rockers and porting and such does. it feels stronger when it runs.

AEM E85 pump died for the second time yesterday.

Last time it did this I had to get a tow home. i pulled it and put a 12v power source on it, it whirled.., i put it back in the car, it worked fine like nothing ever happened to it.. ???


This time, same thing (I was home, thankfully). Key on, no pump prime sounds. I did the same thing as last time. test power to pump, CHECK. pulled pump and gave it power. NOTHING.

So I think it's finally dead.

scratch

Maybe put 12v directly to it with an old DC power supply or something? Mine's been working beautifully aside from not liking to pick up the last 1/8th or so of fuel. Did you try the old pump and see if it's working?

I tested the module. Pulled the pump out and tested it and it worked fine.

Wired it back up and the Riv is running again. 2nd time this has happened no idea why. everything is perfect when i pull it and dissect it. drunk
