Hi Corkman I passed on your comments re a bent float hanger to the mechanic at the local fiat dealer who advised me that I should put two tankfulls of fuel through it and it would recalibrate the system and the fuel gauge reading would correct itself. This does not sound logical to me what do you think I drained 80 odd litres out of the 125 litre tank and after draining the first 30 litres out the
I have received the following response from fiat Professional here is the answer provided by fiat Professional The body-computer cannot be reset and hence the fuel tank cannot be replaced with a different size. I am confused because my camper has got the optional 60ltr leisure vehicle tank fitted and trip computer fuel remaining and range work correctly for that size tank.
Hi Rayc My guess is that if the tank is replaced then the body computer should therefor be replaced as well with one with the proper software if it is hard coded. Anyway in my case I took it back to the main maintenance base for fiat commercial in Sydney and they took out the pump and float assembly. A dipstick showed that there was an 8cm depth of fuel (about 30 litres) in the tank but the fuel gauge

Hi Not sure of the situation in Africa but here in Australia in certain places during winter they change the Diesel fuel delivered to the colder parts of the country because in winter with the normal summer diesel fuel the waxes in the fuel solidify thus blocking the filters as well as being very hard to pump through the fuel system. I have experienced this years ago although in my case it actually
Yes. Sounds like the diesel has gone waxy and is gumming up the lift pump. Let it warm up and hopefully itll recover with no damage.
Hello I have the 2.5tdi Sofim 1991. I dont know why your fuel filter would have been by-passed but The sequence on mine from memory is as your second option tank----lift pump-----filter----injector pump I cant check at the moment because I am away from it. There are fuel flow arrows on the filter top housing on mine. If you also have them it may help you a bit. Good luck with it. Phil
Ive found a wiring diagram which shows the system I hope its of help. Couldnt find a key but I figure that its something like this. CAOO - Ignition B511 - ECU 1211 - tank sender unit and pump assembly 0004 - Dash gauges fuel gauge Attached Thumbnails   __________________ fiat Forum Useful Links Donate to FF    Buy FF Merchandise    Classifieds    FF Insurance
hi both. check that your second battery is holding its charge as i had similar prblem and found second battery required a litre of distilled water once this was done starter battery held its charge as it was not been drained by second battery hence no more starting problems. re fuel problem try injector cleaner in your fuel tank as partial gumming may be your problem espescially if your using supermarket fuel. hope this helps.
Attached is a diagram from the iveco manual for bleeding the fuel system on the 2.8 non CDR engines with explanation included but the location of some of the components would be different on the fiat . I would remove the fuel filter again & fill it nearly to the top as practical without spillage on reinstallation with clean diesel then reinstall it. Then follow the steps as per the attached diagram
Blocked breather causing massive vacuum in the tank You will hear a big inrush of air when you take the fuel cap off.
Im not familiar with the set-up so forgive me for taking a stab at it (and if youve already thought of this) Is it a submersible pump hanging on the cable and delivery tube If so is it actually in the bottom of the tank Or is the pump part of the fuel level sender assembly and the suction pipe hangs down into the bottom of the tank If so I would expect there to be a weight of some sort on the end of the suction tube to keep it down maybe a coarse filter has this come off
Good thinking to run without the fuel cap - that eliminates any tank vacuum problems. The only thing that I can think of that changes as fuel is used by the engine is that the fuel temperature rises in the tank due to the hot returned diesel from the injectors. This is very noticeable to users of vegetable oil like me (not in my ducato by the way). It could be that the low pressure pump reduces pressure

I had the same problem deisel dripping on the driveway only happened with a fullish tank ....... Got underneath and cleaned it all off then looked for leaks ....... The fuel tank looked almost new well the bits I could see did anyway but there was some corrosion around the flller tube weld. Started tapping it gently and before I knew it there was a 2 inch hole in the top of the tank. It looks like
wont start then this is quite likely to be a problem with the immobiliser. If you run a search on the forum there are quite a few threads on how to bypass this (but does require a bit of mechanical and electrical dexterity) Thanks for reply Crosskeeper. Is TDI not JTD seems TDI does not have fuel pump in tank like the JTD has but little info available on TDI would be nice to get a CCT diagram ducato
Hi Ive only just registered to this forumbecause Ive gothad the same problem sometime the fuel gauge works ok next thing its all over the place Ive put-up with this for the last 4 years and have intended every year to do something about it (take out the sender etc) but after reading about this box under the fuses I thought Id have a look I couldnt find the particular box being about 6 boxes there and hard to get at so I lifted the fuse section up to see if I could access it from there no but during the process of moving the fuse container about the gauge that has been reading 34 full for months suddenly went to full as it should (Ive just filled the tank to the top) so until I run the fuel down I hope that by wriggling the wires about has cured the problem fingers crossed. for the last 4 years Ive ignored the gauge and gone by the mileage Ive never been far wrong. fiat forum thank you very much
Turns out my issue is the fuel sender unit within the tank having changed out the voltage regulator it didnt change the fuel gauge. Ive picked up a replacement from a brakers yard and Ill report back.
The fuel system is self-bleeding. Turn the ignition on but do not start the engine. Listen carefully near the fuel tank and hear the pump circulating fuel. Wait until the sound is steady with no gurgling and air sounds. Then start the engine. Good luck.
As you have had the pump out of the tank I would suggest you first check to see if that is pumping just remove the inlet pipe of the filter housing and get someone to turn the ignition on whilst you hold a can or something under the filter pipe. if fuel spurts out the pump is ok if not check the pump and its electrical feed.
If the pump is full of crap then the filter is full of crap and the tank is full of crap strip it all out from the filter back and clean and dry meticulously . Do not reuse the diesel in the filter you need to be absolutely meticulous clean with changing the filter Is your tank rusty Aside from water resuspension of particles in the filter is the main cause of premature failure in common rail httpwww.afssociety.orgspring2011...egan-paper.pdf
hi im am not new to deiselsi am a H.G.V. teck but i reciently got stuffed in a deal with a MAREA td100i intend to keep this as it is ideal to use for sea fishingi have changed the cam -beltoilfuelair filters. to get the motor running i put the fuel system on a 1 gallon can it ran with only the smallest derv knok i then changed the fuel filter (what a mess)full of red and slurrynext came the AIR filter

Thanks Peter I had a look at your website too very interesting. Going a bit off the original topic now

I undid mine in the vice too. Put the lid in the vice becvause its stronger than the body then get hold of the body wearing those grippy rubbery gloves to unscrew it. No bleeding necesary as the electric pump in the fuel tank filled it up again as soon as I had refited it and turned the ignition on. The rapid connectors are just like a garage air line where you pull the collar back to release them. There is a special tool but I managed to do it without.
First make sure the ignition is turned off Remove the air filter housing top. Remove the air filter element itself from the housing - this can be a tight squeeze. Remove the 3 retaining nuts at the bottom of the housing & the 2 x worm clamps from the housing to the snorkel & the engine breather & remove the air filter housing from the engine bay to allow access to the fuel filter. Loosen the 2 bolts
I have a ducato 120 multi jet and Ive had the same problem Stripped the assembly completely and re tried. Problem stopped (for now) I couldnt see where the half tank of diesel had leaked from.
My leak was corrosion around the tank filler tube weld area ..... was easier to replace the tank than repair it.
