Fuel tank and pump, electrolysis on tank? New pump?

[slojim]

Haven't started the gn in too long.  I tried this week, but I didn't get any fuel.  My tank has a little rust inside, not too bad.  It's the original tank with the plastic baffle.  I'm thinking of trying electrolysis inside the tank while I have it out.  Anybody ever try that?
I need a new fuel pump.  The old one was a walbro gss242, 190lph.  They seem to be obsolete, I can upsize to a gss340gen3 or a racetronix 255lph.  I have an fpr and a hot wire kit long installed. I've never touched the return line and I didn't think the 255lph size needs that.  The sender is ok and I don't plan to replace anything extra until I know the car starts.  Am I missing anything?

Electrolysis works ok for very mild surface rust. But after if not treated it will rust even more and faster.
Used to use a product called Kreem coat on motorcycle tanks. Its a 3 part system that lines the tank and works great. Not sure how cost effective it is on a 18 gal tank since it's costs about $40 to treat a 5gal tank.  New Buick tanks are around  $125.
The Walbro pumps you mentioned are all about the same rating. Only difference it the inlet how the sock sets up. All are good for around 500hp. Not sure what the new flavors are these days since Walbro are old school but work great.

There are some companies that specialize in cleaning out fuel tanks.  I believe they use something to line them with after getting them clean to prevent the rust from reappearing.  I know there is one near Houston.

I am with Ed, nothing special required with the pump.  I would check with Cotton or Mike Licht.

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

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