Posted: Tue Jun 07, 2011 17:09 Post subject: leaking fuel pump 2.8 diesel quick fix |
|
|
hi to everyone
joined this site about 6 weeks ago as most members would have done, to gain info on their trucks
my problem was leaking fuel pump on start up, if left just 3-4 minutes ticking over a puddle the
size of a manhole would appear, the leak however would disappear when engine was hot .
after visiting a few local garages ,same reply oooff big job that . ££££ss+£££sss
i thought to myself i wonder thinking back to the days of shooting co2 gas guns and how
the cold inert gas used to shrink the seals on the guns , and how we used to solve the problem
was simple, brake fluid. a bead the size of a teardrop placed on a co2 gas cartridge would soften and rejuvinate
the seal
so heres what idone first i ran truck till fuel light came on then i put 500ml of brake fluid in fuel tank
followed by a fiver,s worth of diesel ran truck as usual, brake fluid burns when hot so no problems with smoking
or other running issues. just top up with fuel as normal when fuel light comes on.
six weeks later no fuel leak from pump ( this quick fix seams to have treated every seal in the pump)
i am now getting nearly 28mpg enginge tick over is also alot smoother even when cold
this may seem a little unorthodox but my pajero is 17 yrs old and doesn,t warrant £300+ repair bills
ps will keep everybody updated (every couple of months ) as to how quik fix is holding up |

Nice to apply a bit of science to a problem. I can see how it works by lubricating the seals and stuff. What a great idea. |

If it works, then great... it'll help lots of people... excellent! But how come no one has ever come up with this idea before? Then again, I suppose someone has to be first! |

I believe the brake fluid triggered my water sensor on the bottom of the fuel filter. Other then that I'v not had 1 single issue. I never had one to begin with but can't hurt to "service the seals" |

Ah, the old brake fluid trick.
Taxi drivers here in Glasgow have added brake fluid to seals for years.
when the power steering box used to leak on the old metrocab a drop of brake fluid in the reservoir used to do the trick.
Only lasted so long though, before it would eventually leak again.
never worked more than once either.

Just an update, light has gone off now over night. May have been a puddle I went through
Edit:
Seems to be going on and off so it must be the brake fluid running through.
