80 Series Fuel Pump Dilemma

I should have mentioned that the vehicle is a 1991 non-turbo diesel Toyota Landcruiser. Duh!!!!

Thanks again.

Jack

Hi Jack,

Had the same with my 1993 80 Series, cost $3500 which included rebuilding the pump and new injectors as well. The system had not been done at all before l got the vechile and this was done at 380000km. l would do the injectors as well to make sure all is well and get the experts to do it.

Most normal mechanics will not touch fuel pumps so that is a fair indicator. I know the work area has to be very clean.
Good luck Pete

So while the mechanic is calling the 'investment adviser'..
You're calling the 'loans manager'....??
Hope it all work out OK for you.

Jack, if you can get your hands on a replacement and you have the manual then its pretty straight forward.

The only prob is you need to get your hands on a dial indicator to set the timing correctly.

The rest is just lining up the timing marks and removing and refitting as per the manual.

The rotary pumps are a little like a distrubutor for timing and you rotate them to get the final timing settings. Advance/retard injection.
If the marks are correct on installation then you can do it by ear and just advance till you start to knock then back off slightly.!!!

I would have a go if I was you....just get a good set of metric flare nut spanners (saves the pipe fittings and great for brake work later on) and see if you can borrow a VE pump timing DTI (dial test indicator) i think they sell them on EBAY now!!

All the best mate.

Matt.

G'day Jack
Many moons ago the fuel pump on my then 80 series diesel (1991 model) developed a severe leak whilst we were doing the Canning and Simpson. I had it repaired in Alice Springs. It was only in need of seals so cost was only a few hundred $. On return to Brisbane I discovered it was a common problem and that Toyota dealers were repairing for a significantly lower price than I paid.
I see you're in the TLCC - you should ring your technical officer (or someone on the Committee who'll know who to put you in contact with) and see what he has to say.
Cheers from a Qld TLCC member.

G'day Jack, I'm with Moose on this and suggest you check the gaskets on the pump. I have a 1990 Cruiser tray with a 1HZ and had the same problem which turned out to be the gasket on the top cover of the pump - the one with the throttle shaft through it. New gasket (genuine) and a o ring for the throttle shaft was about $30.00 2 or 3 years ago and its about a half hour job if your handy with the spanners. Just remember to mark the position of the arm on the throttle shaft so it goes back in the same place. The rubber goes hard after a few years and I see your vehicle is a similar age to mine.

a complete reseal costs around 700, but then the bastards will say you have to rebuild it, costing over 1500... check on ebay for rebuilt ones, usually not more than 1200.

btw, it is very easy to replace some seals on the toyo pumps while on the car (depending which seals), and they are very cheap too.

there is a seal on top which takes about 10min to replace, and an oring on the side which takes another 10min, but if the leaking oring is on the engine side you will have to pull the pump off.

check and let us know which one is leaking, you would normally be able to see the leakage.

Thank you to everyone who responded to my query. Your advice is much appreciated.

Gotta love this site ... I never come away empty when I throw a question to the forum.

Thanks again, and safe travels.

it needs to come off and have some seals replaced . while its out do the top cover seals as well , and have it bench tested. 80 series pumps need to be checked as they go out of timing (td especially) should not cost that much

Hi
generally a leak coming from the engine side will be the mechanical advance cover either come loose or "o"ring has gone hard. Easey to repair, once the pump is removed,you wiill see a a small oval cover with 2 allen key bolts, remove them, remove cover, replace "o" ring (a bearing sales shop will have one) reassemble and use Locktite thread locker on bolts as are common to come loose on older pumps . Hardest part is removeing the pump

I had one with a severe leak, to pull it out put a seal kit through and put it back it was about $1200.

Cheers Steve.
