A bit of an update on pumps.
I've now looked at 3 pump failures running %E. None of them MR2's, and it's a bit different replacing a pump in a nissan or subaru etc, than the pita it is with a 2.
In these cases all were stock pumps, all reasonably high mileage and all running 10%.
In each case the tanks were spotless internally (one a composite tank) and the hoses appeared to be fine.
 
When the filters were removed and reverse flushed, there was a considerable amount of black residue in them. This residue is soluble in both E and ULP. Now this isn't anything new, I've seen this in filters running straight ULP before. It doesn't appear to be dissolved varnish or gum residue, and is consistent in color and appearance. If it was in the tank, or in solution in the ULP, it obviously is fine enough in texture to pass through the pump filter screen but not the fuel filter. I think the pumps have simply died from pumping into excessively high line pressures pre filter...and if that's the case, there would be a drop in fuel delivery pressure at the rail some point prior to the pump failing..obviously meaning leaner AFR's.
 
I think it's more likely to be the stock hoses degrading internally causing this issue, and the E is accelerating the process. Next time I get the opportunity I'll section one of the hoses. Good reason, if your running E, to replace the filter now and do it more often..or fit a larger filter, until you can replace the hoses with E compatible ones, even on 10%. Simply not worth taking the chance of a pump failure, let alone running lean under boost due to a plugged filter.
 
 
 
 
 
 
 

James, on the evo you will find the walbro 255lph pump will support up to around 220wkw easily, and with a slight bump in base fuel pressure 240wkw. walbro 400lph pumps do not fit properly in the stock sender assembly, and the deatsch and aeromotive fuel pumps will support around the same as walbro, give or take 10kw.
 
The FIC injectors will make the car idle like a busted arse if you are doing a reflash (tephra mod etc) and have a fairly standard car.

Yup, still breathing alcohol fumes. Tried the United 100 quite a few times, and it runs on a perf ULP98 tune without any problems. and improved driveability Also added 20% bio-flex to it and ran on a 30%E tune, again with no issues.  If it becomes more widespread I'd tune for it definitely. tho no way am I going to drop my 30%E tune lol. 

 
Yeah that's the issue I'm having as well since the United servos that pump 100 are few and far between. What I've noticed, though, still using the Gen2 JDM stock ECU, smoothness and response is definitely improved over ULP98. Just gotta sort out my DP/wastegate and BOV issues.

has anyone actually used this in their tanks for a while at all? and/or are the any results from the mr2 community?

Haha, of course you can't run it in a car not designed for it silly :) You would have been underfueled by about 30%

I ran the new United E85 in my basically standard 1995 SW20 3SGE the other day, and the car would not stop bunny hopping under load at low to mid rpm, down on torque and power massively, struggles to rev. I've just put 10L of BP Ultimate in to try and dilute the ethanol and that has helped a lot, my car isn't bunny hopping as much and power is much better.

So I personally wouldn't recommend it unless your car is tuned for it.

Lol, haha, yeah I am an idiot

I've used United 100 for a long time with no problems, and I'm sure I get slightly better performance from it but I do get better fuel economy off BP Ultimate.

just_aceyou can only run a % of the e85 with PULP

That kind of 'phrasing' is a bit misleading. You should say "you can only run a certain % of ETHANOL".
E85 means there is 85% ethanol mixed with PULP.
Servos that sell this kind of fuel, don't necessarily put 85% ethanol in the fuel. It is common to see something like 70% ethanol instead, to avoid cold-start problems associated with E85.
I'm sure you already know all this just_ace, I'm just clarifying for other people.
 
Flex-Fuel vehicles are those than can handle any ethanol content in the range from 0%-85%.
