    Guys hang on........you saying there is only one pump for both tanks??

    Then that surge on the LRT must be something else?

    And its very "pronounced"......in town you feel the difference immediately below 2300RPM or thereabouts. On the highway no difference.

    I'll have Jomar call the Previous Owner ........ he told him there's a pypie "pinching" or something along that line, and an easy but temporary fix, we will eventually have to remove the tank and sort the (sounds like) plumbing.

    Wat dan IS Oom Errol reg.......dis 'n ding wat knyp.

    Maybe even a breather? When I opened the fuel cap on Sunday there was LOTS of air escaping

    EDIT: Errr, reset, been looking this up now and this is not a pump but the resistor/control that gets switched in and out to control the fuel pump speed and thus pumping volume. Apparently a bush fix is to bypass this unit if faulty. https://forum.ih8mud.com/threads/byp...sistor.871919/
    The fuel pump/s is at/in the tank as far as I can determine. A regular problem is blocking of the intake sieve in the fuel tank.

    two pumps. Each tank has it's own pump in the tank. But both tanks use the same type of pump.
    The sub tank pump is usually the one that fails, and causes the symptoms you describe.

    Any idea why it is the Sub Tank pump that fails most commonly?

    It doesn't come supplied with a Toyota pump. It's aftermarket on installation

    I understood AboutAfrica's post to reference the factory fitted sub, not the aftermarket one that Petri seems to have.

    Thanks a MILL again on the fuel surge issue Guys.

    Jomar just called Oom Errol again to just ask what the issue may be.

    His response - The Tank moves a couple millimetres, and then that surge thing starts to happen. May be a breather or whatever pypie pinching. He has had this issue more than once, they then jack up the tank and re-tighten the "strap" again, and then the surge is gone (temporarily).
    So - with my very limited know how:

    1) It can be the fuel pump IF all else (breather and all pipes) are 100%, and fuel/air flow is 100%

    2) Can be as above (pinched pipe etc etc), and that's why the "surge" happens at 2300 and higher RPM, the "blocked" whatever opens up due to increased fuel pressure.

    I guess both scenarios above are "possible".....

    Kar loop mooi. Hou nie van daai dual carriers nie, die goed bewe as jy op sleg pad ry en jy kan GLAD nie iets haak nie, daai tyres is innie pad.

    Binne BAIE mooi, die rear load bin het egter maar sy krappies en goete op maar die res van die interior is fault free. Matte soos nuut, kort net nog so paar keer se skrop.

    Bande is maar so so ...... en ek was nog nooit die grootste BF Fan nie, maar hulle is vir eers OK. Revs is ook hogerig, so 3000 teen 120, ek dink bietjie groter profiel (hoogte) tyre sal mooi loop.

    Nog nie enjin laat was nie, wil eers mooi van alle kante af kyk of mens 'n sweterigheidjie of nattigheidjie iewers sien, sover lyk hy 100% skoon.

    Body is nog 100% Virgin, die side plates/mudguards etc etc ook nog mooi.

    Rims ook nog mooi.

    So.........ek dink baie nice original basic GX efi, as NEW geregistreer op Natis, maw 1 Owner, en FSH..........n BAIE nice "base" om van af te werk, en die moeite werd om mooi 100% uit te sort.

    Behalwe vir die rear load area, wat maar krappe ens ens het, sou ek die res van die interior nogal amper as "mint" beskryf. GEEN krappe of snye of goete nie, die center console is soos nuut, cubby is soos nuut, rerig baie baie mooi binne opgepas.

    Die is ook nogal vir my nice.............Toyota Book of Life, Nuut gekoop, Eienaar in Diensboek en Eienaar op 1999 Natis is selfde Persoon. Tot die Salesman se kaartjie en die Kar se "Toyota Slip" is nog vasgeheg.

    Maar net vir my nice om te he, ek like dit.

    Elke Diens by Toyota, ongelukkig die laaste een op 249000 Km by Indie, "The Garage".

    Maar hys nou op 260000, ek sal hom beslis sy diens by Toyota gee sodat ons daai Toy stempeltjies weer regkry.

    Eish Petri baie mooi 105 daai.

    Revs op 3000 klink reg, ek het 33's op myne en die revs sit net onder 3000 (die magic fuel pomp spot) as ek so net oor 120 km/h ry.

    Extremely helpful thanks a MILL.

    Interesting Post in there.........why not have the LRTank just "garvity feed" the Main tank, you then only need one pump, and there's only one place to look at if things go sluk sluk??

    Just a Thought?

    Anyway - thanks again. I'll do that Carb Cleaner thing again anyway, like my Posts in there with one of my previous EFI's I had.

    Dankie Weereens

    Update ........... left the car at my pal Klannie, he's a propshaft/suspension Guy, I ALWAYS take my stuff to him to check.

    Nothing that he can see that needs fixing underneath......mountings, bushes, etc etc etc all well.

    Happy Days.

    So.....issues I need to look at (mechanical) for the foreseeable future

    1) Clutch - gear changes are not as they should be, and "clunkiness".

    2) Service - plugs, oil, filters, clean up sensors, etc etc

    3) That Sub Tank issue, but will be able to jump that hurdle (thanks again Mike N).

    En ja........dan kan mens so bietjie beginne mooimaak en skoonmaak

    My IDEAAL sal natuurlik wees om die kar weer te standardise......original Subtenk terug, spare onder die kar, en daai plastic bumpers replace of refurbish "back to new".

    Hou NIKS van daai twin spares agterop nie, en sover beslis ook nie mal oor daai LR Tank wat so surge nie.
