and the results - look a lot like the before pics. as I said, the orange stain is gone, and I dumped out a lot of rust - covered the bottom easily of a 5 gallon bucket.

here's a pic of my electrolysis rig. My wife was super uncomfortable I'd electrocute the dog, so I only ran it 8 hours while I could keep an eye on it. I think I used a cup and a half of washing soda in the full gas tank. I did get orange goo coming up, and I did have to replace a little bit of water.
You can't see it, but I used an old steel edger blade, due for replacement, as my sacrificial anode.
I read about flash rust - holy cow - the edger blade rusted up in like 2 minutes, well before I even had the fuel tank drained. Anyway, once I emptied it, I fogged it with WD40.
It was a neat experiment/learning - but I can't call it succesful - I probably needed to go for 2 days.

here are some before pictures of my gas tank - the phone is upside down in the hole, facing 4 different directions - so your seeing the inner roof of the tank above the plastic baffle.
The last picture is looking down in - note, this orange baffle rust stain came out during electrolysis.

I've no intention right now of running E85 - I just figured the encapsulated windings would be a little more robust and the overall construction maybe a little more corrosion-resistant to regular gas. I considered a 340, and maybe the whole sender, but I'd have to run a return line, and I don't have injectors to take advantage of the extra gas. So for now, I'm probably just going to get the walbro 255, probably the kit off of FTS. The kit is 2x the bare pump, but all those little parts fell apart when I pulled the pump. It appears the correct gas tank is at rockauto, SPECTRA PREMIUM GM307C. My electrolysis experiment took out a lot of rust, but it visually looks the same with plenty of scale, so for <$230, I guess it's time for a new one.
I am sorely tempted to get a cheap fuel pump off of rockauto - they run from $11 to $50 generally with a full install kit minus the $5 sock - I just want to start the car and see what else is needed, and when highway stars has the short rubber fuel lines in stock I''ll want to drop the tank again and replace mine - but I wouldn't be comfortable driving with an under-rated pump.

The world never ceases to amaze me. Takes all kinds, I guess

Buying the truck was an adventure. I put a battery in it and it lit right off, we let it run for 30 seconds and moved it out into the driveway to look at it better. I kept smelling fuel but thought it was just running rich, as it's sat for a while. About a minute into it idling my brother told me to kill it. Nylon fuel line not routed properly, spraying fuel onto the drivers exhaust manifold.  Needless to say we stood back and informed the owner that he might want to get fire extinguisher. It turned out to be an non issue but he had paid a shop $300 to fix this fuel line and it could have cost him his garage/house/truck/life Quick negotiation and we loaded it up. I have repaired the fuel line so I can run the truck and test stuff before I disassemble. This video shows the nice repair job: https://youtu.be/_ryb_pqMqTc

Lots has happened around here.
Yesterday I sold the 04 Silverado 1500 Reg Cab short box - got what I paid for it 2 years ago.
Picked up another 05 GMC sierra 1500 crew cab short box - cheap. Drove it on the trailer. Frame is cracked. It's an SLT with leather, and is pretty damn clean. Going to horde some parts, sell some, and scrap the rest.

255 with 80's took me well into 6's in the 1/8th with race gas. The 340 might need a larger return line. Some get away without it. Guys on the other board are saying some of the E85 they get is lower. It's a crapshoot. If you're gonna run E85 I'm fairly certain you need bigger lines...and possibly a 450 pump. Cruz and other vendors sell the larger lines. Racetronix is here in Canada in Scarborough. Expect the shipping to be a little slower getting to you.

Takes about twice the size of pump than the usual 10% ethanol. E 85 is very corrosive as well.

Thanks. That place is on the north end, a pretty long haul for me, and considering I can get a new tank for $200 give or take, not the choice I'm making today. I called around me, no one seems to be interested in cleaning. That is ok, I'm excited to try hydrolysis and all I'm trying to do is get it started before I make bigger decisions.
Yep, I've got a pump from full throttle and from racetronix pulled up. I note the racetronix ones say they are e85 friendly, while the tpi/walbro ones do not. Seems likely they would be, but they call it out on their bigger models
I'll take some pictures. Finding tsp took 3 stops
