the same lines that I referred to as "vent lines", which is not the really the current terminology - lol

MattLS400

hmmm....This is the manual i used,

http://www.ls400.ru/lexus-89-2000/il...uepum/comp.pdf


please inform me which line is the evap/ vent line...and how could this possibly lead to a gas smell on the outside? It's inside of the tank...

it's not shown there because that is the SFI portion of the manual, not the EVAP portion (which is under emissions iirc).

I too got a gas smell in my 96 for a few days after I changed the fuel pump. It was from the gas which dripped into the cabin when pulling the pump assembly out.

MattLS400

this too was my intitial thought...But its been 3weeks since this pump has been chaged....I highly doubt that smell can remain there for such a long period..And I drive with the windows down...so the cabin gets a good "air-out"

I have filled my Gas tank to the full level, drove the car then jerk it by applying brakes suddenly. Now with the Back seats off, I saw that it was leaking from the bottom 8mm bolts on the set plate


N.B : NEW OEM rubber gasket was used !

I honestly dont know why its still leaking, I tightened the bolts in the respective opposite technique as advised.

I think I shall have these bolts replaced. Where can I locate these 8mm bolts?
What is the Torque to apply on these bolts ?

LScowboyLS

how could you have torqued these down correctly, if you didn't know the correct torque?

PS - too tight will cause something to leak just as fast as too loose!

the correct torque is 26 inch-pounds (2 ft. pounds) - you need a special torque wrench to even measure this! (it's barely hand tight! )

MattLS400

I used my discretion?

LScowboyLS

here is one of mine:

LScowboyLS

your discretion probably has them at 15 or 20 foot pounds, rather than 2 - that is why it's leaking!

you may have ruined the seal cover, from distorting its shape

this is why you don't do this stuff without the factory service manual, silly! - best money you will ever spend!

LScowboyLS

get the service manual, a new seal plate, a new gasket, and a wrench like this one and you can get it to seal right!

it's also the wrench you need for torquing transmission pan bolts!

MattLS400

lol .....sigh....ok guess i gta get a torque wrench...and Yes im sure the seal cover is distorted because when i removed the set plate, upon re-installing the seal, it was not re-alligning with the holes, it was a bit off...

So next on the purchase list --
Another Seal
8, 8mm bolts...where to locate these specific bolts though ?

LScowboyLS

the dealership has the bolts, but if you have distorted or warped the plate, you will have to get a new subassembly

and get that manual ordered!

I added a link to a torque wrench on ebay that would be ideal to post #26

MattLS400

Yup, bid placed already. Looking for a subassembly on ebay atm

LScowboyLS

the problem with a used subassembly, is that it may have the same problem!

PS - if you want a new torque wrench, this is the best deal I know of currently
