Re: [Amc-list] gas stank etc

Sounds like the gas tank thing is under control! The Caswell product sounds good, but I still plan on using the Hirsch Auto product -- it's been good to me over the years! For a badly pinholed tank the Caswell epoxy might be a bit better though. 

Why don't you put some laquer/paint thinner in a pump up pressure bottle as used for gardening and run that through the fuel line? A quart or two should clean the line right out. Or use gasoline. Just put a catch basin at the tank end, shoot it in the fuel pump end.

Well I seem to be moving in slow motion on the little 63 American, but I am 
moving...

Got the gas tank cleaned, repaired, sealed. I think it worked out OK; scraped 
clean, cut two 5" holes in it, hot-tanked it at a machine shop (after I 
drained and detergent-washed gasoline out), sanded it inside with 100 grit (I 
have long arms), screwed and epoxied 16ga patches over the access holes, 
ground the screwheads nearly off, rinsed with lacquer thinner, then Caswell 
epoxy sealer. 

The Caswell stuff wasn't cheap, about $75 (for two kits, it's a big tank), but 
it worked really well. They warn you have only 20 minutes working time, so I 
was a bit worried, but for nothing; working time (eg. still runny) was closer 
to 30 - 40 minutes. Ambient temp was 80 degrees. I stirred the hell out of 
it, rotated the hell out of the tank so I'm fairly certain it's 100% covered. 
It took a few hours to harden (had me worried for a bit) but it sure is a 
tough coating. I did this late afternoon, relatively slow cure all night, 
then left it out in the sun all weekend. 

The sender was equally rusty, but that cleaned up OK, surprisingly, and the 
resistor card and wiper are OK, and it seems to be working fine. I got a 
float and O-ring kit from Galvin's so I'll be in business shortly.

I have 12 good pushrods so the rockers can all go together next. That will 
complete engine assembly.

The gas was badly contaminated, and I haven't changed out the fuel line nor 
fuel pump. I'm thinking will just crank the engine and run a quart of gas 
through it to get out the bulk of it. It was all gas-soluable so that ought 
to do it. Makes me a bit nervous though, maybe I should just change out the 
whole line.

I got all the suspension-repair parts today. I get paid Wednesday so I'll over 
the bushings then. 

Then I can drive it and find the NEXT layer of problems...!
