the drain from the ac might be blocked

no not quite there yet , those pressures are at idle, the correct pressures are 36psi at idle 38psi at run give or take 2psi only , now factor in fuel use and that pressure will drop, the pump has to supply at least 2L of fuel at the correct pressure to supply the motor under full load
PS quick test stand where you can hear the pump and have some one clamp of the fuel line slowly , this will make the pump squeal under the load or it will race as the pump cavitates ,fuel pumps are positive displacement so dont close it off any longer than a couple of seconds, if you can close of the line and the pump continues to run, its stuffed. IMHO

there's a tool for that (helicoil 5334-14 sav a thread ) this tool is 14mm/1.25 pitch not shore its the correct thread size but will give you the idea . if you require to do this put piston as close to top as possible and use grease to collect as much of the cut material as possible , a piece of wire with grease on it can be used to collect any material in the bore . cut 2 threads and remove tool and clean reapply grease and do agian untill all threads cut , its not a hard job just time consuming

the cure for climate alarm ism listen to this davew scroll down to sound of music pic

WOW you lot over their are up against it , how do you think all this would go in Australia , cruising the Nulabor 500+kms from fuel stops 60+degree roads surfaces and nothing but red dirt for 2000kms (3days from melbourne to perth) .kangaroos that run faster than your car and look down at you through the windows (go the space saver) but all the EV drivers will be ok because we now have diesil powered generators for EV charges for them.(yes its a thing). this bullshit
about the environment just keeps getting better
whats the go with the election , which way do yo see it going , do you think corbin will win or boris

ok i have read this post front to back , i think your chasing your tail with all the trims and variables, you have forgotten the basic fundamentals off fuel injection, PRESSURE IS CRITICAL . running at 26psi at idle is not good, its 25% below optimum running pressure 36psi . all the variables are trying to work within their parameters but the fuel is not there so there all over the place . yes do the fuel filter first and recheck pressures , if you need to apply heat try and find an old electric plumbers soldering iron and use that , no open flame. if no improvement then its the pump. worn pumps have a habit of cavitating especially when the fuel is hot and this is where i think your problem is?
PS this my 2 cents worth and is a generic answer for all injection systems ,( not gems directly related) as i look at all systems to be the same . you must have noticed a drop in power or fuel usage to be different and in saying that these things can creep up on you and not notice that its not performing as it was until you have trouble towing the boat over that hill that you use to fly up .
PS don't forget the fuel pressure regulator as this can be an issue to

then look for a Lucas injector flow chart

to race anything can be good fun with the right people
we have mower racing to , and don't the open class go (bleeding kidneys all round)

good to see some competition , right up their with barbie car racing, all down hill them hear.

just put stan weiss in to google

the only electric vehicles that we will be driving in the future will be mobility scooters , might convert mine to petrol , who wants a race?
PS hi davew so my name is craig and i live in tasmania and drive a 1997 p38 petrol so what model do you have ?

ok that sounds good that you did remove the box , i had a vision of you trimming the flaps on the top off the box and not actually removing it . if yo have good end float and all is free it should be good. how did you go with the white gear on the side as they can be tight too

Hi davew
good to see that we final agree on some things
so what model range rover did yo say you had .

(http://StanWeiss-electronic fuel compatability) is this what you are looking for

did you remove the heater box from the vehicle , which flaps did you trim.

hi davew sorry if you have taken my comments as offensive as that is not what i was trying to put forward , so i apologize for that, sorry.
my point is that their is another side to this story and it's not being heard because they say the science is in and you should just believe it, no sorry im not going to believe a computer generated concept, that is simply not real , it's a concept , a possible maybe at best . the info that you put forward is just that , a scientist put an algorithm into a computer and came up with a concept that under certain circumstances and the wind blows up instead off down this is a possibility and because scientists are scientists they agree that under those circumstances its a possibility, this was evident in the first 3 words of the reply ( a science consensus) sorry davew but i only deal with whats real , i have learnt over the years to question everything and to not accept the norm
my real opinion is that the carbon debate is a rouse to distract the people from the real issues that are staring the powers to be in the face ,pollution, population, plastics, politicians etc. these are today's real issues not carbon . no amount of carbon is ever going to hurt any human or animal ever( unless a tree falls on them, unlucky)so im sorry davew that i dont agree with your concepts and that the science is not their . i live on an island and if the water was rising it would be a visual thing by now , it's supose to be a meter or so higher according to the computer modeling , sorry davew im just not seeing it
while i accept that people have differing views i don't accept that their is only one side to this issue.
PS back to the real question , do you still have your Range Rover . it's ok to yes , it's old and recycled so its ok to have one in my opinion.

well what a load of ....... ,how have you's managed to be manipulated by someone that simply can't be honest with you ,and state exactly what he drives . he says that refurbished vehicles are a savior to the environment and then uses it against you (our vehicles are 20 years old , saved from the scrap heap) yes we all could buy new but why ?
maybe davew can explain where all the money is going and how it is being used to save the world (administration costs?) or how the pacific islands are stating that they are sinking into the ocean when in fact they have increased in size by 70+ha nearly 200 acres or how one scientist can can make false statements about the great barrier reef , saying that an area had 80% permanent bleaching when in fact it was 40% of which 30% would recover within 3 to 4 months, the other scientist that worked on the same issue that stood up and corrected his college was SACKED (unfair dismissal case , 1.2 million dollars compensation, yes he won)
maybe davew can explain why someone that speaks out is attacked and belittled because they don't believe or have a different views, it's like religion you are a believer or not .it will be interesting to sit back and watch exactly what these kids do in 20 years time when they have to deal with the disposal of solar cells li battereys and the like ,. a problem they created for them selves, i could go on but why, no one is going to change whot they do, no child will walk to school or tell the teacher to turn of the air conditioner or the heater . they only showed up because it was a day of school , do it on a Saturday and count the numbers
where did greta get the idea to crap in a plastic bag and dispose of it in the ocean, Iceland i guess, they just put it in a plastic bag throw it on the beach and watch the tide wash it away . good luck pushing it up the hill, thats the contents off the plastic bag!!

on the side of the injector is a number, google it and do a comparison , with one being bosch and the other a lucus i doubt if they are directly interchangeable

when you say cleaned up the flaps do you mean you trimmed up the rubber edges around the flaps or modded the inside of the air box. the real issue is the box shrinks and the end float of the shafts dissapears this is where the problem is if the flaps are tight
ps when the lube dries it will fault again?

how are the diesel with gas injection systems with emissions . I know they go well and run cleaner internally
my vision of the future is electric town vehicles and petrol diesel etc for the country . how many charging stations would you need to cross the Nullarbor in Australia, 3000kms. you can't use a standard power point, lets get real.
