Wow! This is a great fuel pump gasket install! Seems like this job will takes about 1/2 - 1 hour once you remove all the plastic coverings. hour for the repair. And also being a knowledgeable mechanic. Did you have to calibrate anything with Techstream after you did the gasket repair. Great job and one hand too!
I think I hear a knocking coming from one of the fuel pumps you did in this video. Do they knock before giving out? My exhaust smokes a bit and smells like gas also. This a bad fuel pump can cause this ? Thank you so much.
These pumps tend to get loud throughout time. Knocking, loud metallic ticking sounding. If it bothers you that much, you can replace it. It will happen again though. No known issues if left alone, just replace gaskets.
I have some light smoke coming put of my exhaust and already tested to see if I had a coolant leak into the engine with that head gasket blue liquid test. Luckily no issue there. I have a leak from the fuel pumps though . Think if i replace the gaskets ,that should fix the exhaust being too lean ? Thank you.
@@sgbabyflex Coolant leaks can be tricky to detect on these V8 motors. Unless, it gets to a point where you’re constantly checking & refilling the coolant reservoir. When cold, your coolant should sit on the FULL line. When warmed up it should be above FULL line. In the 2URGSE, we discovered valley plate leaks by sticking a borescope camera in a specific spot by the passenger side runners. With the camera you’ll be able to see the coolant seepage. I honestly, don’t think a leaking fuel pump gasket will cause smoke to exit from exhaust.
I'm have Lexus gs350, we finished working the engine, when I start the car it works well, but when the steam like 3 minutes it will trip off, and won't start until the car is cold before it will start. So I scanned the car and it showed p1235, high pressure fuel pump circuit. Pls can these leads to these problem?
@@Autoenginecheck I believe I have found it. Is it two fuel lines that are to be disconnected? And then there is an electrical connection in the middle?
Thanks for the video, is there a quick method for bleeding the fuel off the high pressure line?
no way
Did you put grease or motor oil on the black diamond gasket? I see it is coated with something. Thanks
Yes, I put grease on the black diamond gasket
Thank you for the step by step 👍🏽 this will help me on my gasket replacement
Thank you for staying by
Do you know if the parts and the steps to fix this will be the same for an 08 Lexus GS460 since they both have the same engine?
The same. But different like pipe switch system is same
Thanks FOR comment
I’m going to make a video for the Lexus GS460 on this replacement.
@@ajoros heck yes brother. Looking forward to it 👍
The gasket all must change new one right bro?

No need to calibrate but the first time the engine starts will be delayed by a few seconds
Why didnt you change the o-rings of the hpfp?
oil did not come out through that o ring and hpfp ring not available
thanks YOU so March sir
@@Autoenginecheck Is a leaking pump typically those orings?

Thank you sir
Dealer are there to fuck you over nothing more or less

@@EjikeEmmanuel-bt5ljdid you figure it out
Hey on a 2010 LS 460 I was told that it was two sides to the fuel pump seal is that true?
Yes sir there are 2 high pressure oil pumps on both sides you can see in the video
How did you get the pressure out of the fuel lines?
There is an fuel pump under the back seat and its pipes can be opened
@@Autoenginecheck I believe I have found it. Is it two fuel lines that are to be disconnected? And then there is an electrical connection in the middle?
^disregard. I got the lines removed. Thanks for the help!!
@@Autoenginecheck what if I took this off without taking out the pressure from the fuel lines
@@Autoenginecheck do you have to bleed off the pressure before removing the front hpfps
Thank you for the sharing.
I got charged $340 for that!
That pump probably have lots of pressure, how u released it before taking the pump out?
Loosen the high pressure fuel pump pressure pipe nut slightly and the pressure will drop
Mine lots of fuel pressure came out now I have low pressure in the lines how do I get high pressure again so the car can start n run
@@arielcastro34did u ever find out how?
That was easier than I thought, I could have just bought the gasket kit and jumped into it.
thanks FOR comment sir
@@Autoenginecheckhey is it the same pump for 2006 Lexus gs300
Yes@@silentbutdeadly3466
