a mate got a 87 hilux with a 2.4 diesel in it and it cuts out after a little while driving. like looses fuel, cxhanged the primer pump and the filter but its still doing it. any help guys??

cheers.

there may be a small crack somewhere in the flexi fuel line somewhere...?

i know my diesel in the dyna was doin that when it had the above...

so i should look for a small leak? or would that be sucking air into the injector pump?
cheers

i had a bit of both dependin on acceleration etc..

look for a small crack allowin air to leak in under load.. ie when engine rev's..?

sorry, i only found mine by lookin about.. it might bleed out when it stops? luckily mine bled a little diesel when stopped..

good luck!

cool, thanks for the tip much appreciated

fit a bit of clear fuel line on the pump return and watch for bubbles. if any put it on the inlet side and see if its the pump itself.

also don't forget fuel solenoid itself or connections.

Oh yea thats a good idea, there appears to be a diesel leak at the diesel pump. not heaps but could that be the cause

Hi,
Have you checked the in tank filter that is on the end of the suction pipe, try blowing some air down the fuel line bck into the tank and see if that improves the situation, if it does take out hte filter and give it a proper clean. Had this prblem when I was running veg oil.
Cheers

if its leaking fuel out the pump then it will be sucking air in for sure. usually they will suck air in before they leak fuel out. once you get a big enough air bubble it will starve the motor for a bit, then come right till the bubble builds up again.
