Not paint as such but some kind of electroplating(?) was on the tank still around the areas being touched up but there was always going to be some overlap with the paint covering it, I think it was just the solvent reacting but all good now.

Mine painted up without an issue. Used rust resistant paint.

I initially used some etch primer in a can and I think the solvent in it must of reacted with the plating, after removing all the bubbled up plating I then used some rust guard epoxy enamel without issue.

Was there any of the old paint still on the tank?
The etch primer could have been reacting with that, but hard to tell I suppose.
Painting is a bit of a black art!!

I feel your pain there I had the exact same problem with that breather/baffle thing. In the end lowered the rear of the tank, reconnected it and then fed it through the gap as I raised the tank.

Yay!! Just got it all back together, and my car lives again!!
I can confirm absolutely a PITA job!!

For anyone contemplating slipping in a new fuel pump:
In case you don't know, first of all you have to disconnect an awful lot of of stuff; then to get the fuel tank out the front must be dropped first and then moved forwards to allow the filler pipe etc to come out of the gap in the bulkhead before the rear of the tank can be lowered.
Putting it back is done in the reverse order, but I had trouble with that @$%^& evaporative separator thingo.
I suspect it might have been easier if I had assembled the hoses to it first before I raised the tank and then fed it through the gap in the bulkhead along with the filler pipe etc.
I probably did it the hard way by not fitting it until after I raised the tank in place, finding it it very difficult to re - fit the 2 bottom hoses to it.

Yeah no doubt that drain is helpful, I lowered mine on block of and ran the pump to empty the contents into a jerry can once it once out.

Also didn't realise the heater pipes above the tank were a single piece, mine must of rusted out previously as it has heater hose there instead, I did wonder what was going on as it certainly didn't look factory fit with jubilee clips on each end.

On your first pic what's that at the front end of the tank? almost looks like a drain point? only query it as mine had nothing on the tank there.

Also i'd be wary as to what you paint the tank with, not sure how these are coated (electroplating of some sort?) but it reacts very badly with the paints I used. It all bubbled up and you could then just scratch all the plating off easily with your fingernail.

Yes it is a drain plug.
Very useful, and you really need it empty to lift it out since a full tank weighs nearly 50 kg.
The paint on my tank looked pretty good so I didn't re-paint it.

AFAIA the earlier sw20's upto about 1993 had drain plugs in the centre of the petrol tanks. Later models post 1993 do not have them for some reason.
I maybe corrected though.

Your tank looks very clean. My internal baffles were completely rusted out.

The pump feed screen eventually goes brittle and breaks. If the tank has rust flakes or sediment, these then enter the pump and will eventually jam it. Long layups, stale fuel and especially E85 will make this happen faster.

If you are in there replacing the pump, consider the screen to also be a critical "wear and tear" item.

Buying from the authorised dealer is the best avenue, even if it’s a few dollars more. eBay “genuine” is rarely a genuine product. Fuel pump based on quality, performance and noise (imo);

For a stock or slightly modified 3sgte/3sge, imo Raceworks 265 lph e85 safe is the best. Authorised dealer in Sydney ships Australia wide. Around $150.

For a heavily modified Mr2, above 1000cc, above 20psi, walbro 460 e85 (new 274 model with improved pressure relief valve). Around $180.

Many Toyota genuine parts hold a quality above aftermarket, others are outdated technology.

Thanks for the advice.
Yes I am aware of problems with the brass heater pipes but luckily mine are all good with no corrosion, and the tank also appears to be in very good condition with no rust anywhere inside or out.

BTW, although there are a lot of cheap replacement pumps around, there has to be a question mark over their quality. I didn't want to take the risk so I got a genuine pump from a Toyota dealer, and although expensive I thought it was good insurance for such a vital part.
If you ask Google, there are reports of many cheap 'knock off' pumps around, with blatant markings on the item as well as the packaging that looks exactly like the 'name brand' genuine items. Of course that doesn't only apply to fuel pumps, but that's another story.
Are any of these worth bothering with?? Who knows??
