Don't mean to hijack just feel like this is a similar situation. I also plan on running a fuel additive for E to help keep things functioning.

The DSX in-tank still uses an OEM type fuel bucket so that will definitely help so not quite apples to apples with the Fore Triple. But if you know you’re going to be driving aggressively I’d still keep over 1/4 tank to help keep fuel temps reasonable. Some ethanol treatment when the car is sitting doesn’t hurt IMO.

I never personally let the tank get below a half, previous owner i have no idea how ever, when i picked up the car it was on e barely able to keep running immediately had to take it to the gas station across the parking lot.

funny how everyone is different between how they take care of things.

Just to follow up for anyone that may have issues in the future and is searching, ended up replacing all 3 pumps in the tank, took it out today to the local airport that i have access to held 75 psi all the way through the top of 5th gear around 170ish no issues now. headed back to the dyno to check the power out now that its maintaining the lambda im requesting all the way to 7200

DW suggested adding Power Plus alcohol additives for helping the lives of their pumps. Katech uses (at least that I know - mine are DW) DWs, so that's what I add to my tank. I, also, add E' stabilizer, which didn't seem to help when I just pulled my pumps. I'm trying an additive with biocide next, I think. It should be here today, but I'm not sure if it will help, as I won't be pulling the tank to check the pumps (unless I have to...). I know all of the times I've looked at my pump screens, I've found weird goo, and that was with adding the popular stablizer/treatments for ethanol. Anyways - it might be worth considering at least an alcohol-type-fuel treatment to help lubricate the pumps.

I use klotz uplon in all my performance vehicles to help lube fuel, I get a hell of a deal on it being a dealer for them but its one of only a few additives I know of that actually works with e85 and doesnt fall out or form gel like compounds. I ****ed up years ago and added lucas upper cylinder lube to a tank of e85, my injectors clogged up with in miles from the gel like formations that were formed. learned my lesson on that one.

i have to admit you're giving me pause in using the lucas stuff you said you were using now...

Honestly you're better off just using fresh fuel all the time and driving it a lot. I do development work with klotz on oils and their other products. Regardless fuels do need additional lube however anytime you add anything to alcohol based fuels you run the risk of chemical reactions and formation of these semi solid gels/goo. If the car is to sit or not be driven more then twice a week or more you're better off with 93 or leaving the tank full of e85. A lot of issues come from sitting or from fuel evaporating/drying out in the tank that's when you start to get issues with e85

Roger that! Thanks for the insight!
