bummer, don't know where i will find these rings locally. longo lexus and carson just said they don't have them and they can't locate any.

 

Sewell Lexus

Chose the o-ring (fuel pump) and order two of them. They have labeled it mistakenly as fuel pump ring, it is in fact the ring for the regulator.

 

here it is:

looks like i will have to order from sewell or carson since no one seems to keep these in stock. Thanks Och.

 

I can measure it if you are able to get it locally.

 

so looks like the part # is used on other toyotas like the corolla. http://www.dealerdirectparts.com/200...-corolla-4.htm
So I'll just order it from the local toyota dealer. wanted to fix it today, but i'll have to wait a few more days.

 

that would be great! i would need you to measure the smaller ones. If I knew the size I could go to the local mcmaster warehouse or harbor freight.

 

Its 3.5MM x 8MM ID

 

thank you.

 

so, i think i've found the problem. I found a crack in the washer that goes between the fuel pump and the filter. Anyone know of a parts car in the socal area. I'll look but I don't think that was is sold alone.

Need a confirmation also for when I re-assemble. The black washer is supposed to be assembled with the flat at the bottom like the 2nd picture right? I'm pretty sure the way it is in the 3rd pic (flat up) would be wrong. The flat looks down in the manual, but it's hard to tell.

 

Call this guy: (626)244-4989 He has lexus GS parts cars, real nice guy. Forgot his name though.

 

glad u found the issue but WHY post that in here AND make a new thread asking the same info....this is how we get so much clutter
