fuel tank

[1Lzook]

i have a
82 sierra swb was a 1L now with the g16b

my fuel tank is only taking 26L to fill and it starts spitting back out a me after i put about 17 in and i have to go real slow,
there is no visible dints and i cant remember hitting it,

any ideas why my tank has dropped in size??

Have you ever ran the tank dry or are you going off the Fuel guage?

Maybe the guage is out and you are filling it up more often than you use to?

My tank only holds 27L and that is because of the massive dints i have in the bottom.

And with the fuel spitting back at you, hmmm maybe you need to check the tanks vent line or something cos as you fill up the air has to escape somewhere and maybe it is doing that through the filler line at the moment.

Just my 2c worth.

Cheers

I reccomend taking the tank off and cleaning it out.
checking all that line aswell

I did mine last weekend, with a mate, and only took 2.5 hours.
It's raised the performance 10 fold (accuctly by about 20%)

yeah i cleaned it up abit and noticed quite a dint in the bottom, there was that much mud caked on i didnt remember hitting anything either, so yeah ill probaly pull it off on the weekend blow the dint out of it with the air gun and then replace all the breathers and shit because i think there all caked up,

cheers for the help guys

I remember CAP5iz having this problem,, wat it was with his was he got a new exhaust , but they ended it so that the hot exhaust gases were passing the fuel tank which in turnn sucked the tank in and the top of it colapsed inwards....
