Question about Ford F-250

1 Answer

My 1986 F250 (4X4, automatic, turbo) has begun to leak diesel from various points surrounding the fuel injectors and associated fuel return lines. I had a visual inspection of the truck and the mechanic told me to replace the return lines (kit:$140.00 labor:$350.00). I just wanted to know if something else might going on that would cause the whole fuel system to start leaking at the same time. I am hoping to adress the root of the problem, not just start replacing parts and work backwards.

    Thank you. This solution makes sense. Why couldn't my mechanic have had that insight?

No the mechanic is right, this problem is caused by the new (in use about 12 years) clean burning diesel fuel mandated by the Feds, it eats up all the injector seals, the new seals are Viton synthetic rubber and are not affected, ford was doing this repair for free for years as it is a fire hazard, we did hundreds at my Ford dealer, I really suggest u have the Ford dealer repair this, there are other parts that may need to be replaced as well, the injector pump seals fail also.

My 1992 nissan terrano blows to much black smoke .how to fix this .some say i have unbirt fuel?


if diesel and turbo , check turbo operation of for holes in the intercooler
if turbo or naturally aspirated check/ replace injector tips as black smoke indicators squirting and not atomizing
if petrol check for excessive fuel pressure, faulty injectors , leaking injector seal
regardless of petrol or diesel --black smoke indicates incorrect air / fuel ratio ( too much fuel) so injectors, intercooler, bad turbo or blocked air cleaner are all candidates for the fault

Diesel leaking where the fuel line bolts to common rail.have replaced washers&orngs on persuresensor


take it to an accredited diesel specialist shop as pressure there exceeds 25,000 psi unless it is a injector return line where it will be low pressure
could be a cracked line
at any point it is not a job for DIY

My hilux 1kd-ftv wont start 3.0 d4d return fuel line full pressure


if it is a common rail diesel then the pressure in the return line would burst it as the line is not capable of 25.000 psi
so the return line will have low pressure if it is blocked some where

have the injectors tested as there may be a tip seat problem that prevents it from starting and the compression pressure is making the pressure in the return line past the needle

Have a 1986 golf diesel it ran out of diesel and I


Are you certain that you put diesel fuel in the car? Had to ask that question. How long did the car sit before you refueled? If it sat for a while and if the temperatures and humidity were enough to produce a build up of water vapor, that might keep the injectors from sending "dry" fuel to the cylinders.

Just running out of fuel won't harm the glow plugs (hence poor starting) and won't require need for a new battery unless the current battery was failing even before draining the tank.

Check your fuel lines, hoses, fuel filter, injector pipes, injectors, but most likely a worn seal on the front of the injection pump and fuel leaking out telltale/bleed hole.

Have a good poke around all the fuel system and you will eventually find it.

1994 f350 turbo diesel won't start


Just with what you have said I would say its time to drain and or replace your fuel filters (there are usually 2: a primary and a secondary)

There could be a clog in the fuel filter, kinked lines somewhere (so check the lines make sure they are working) you could have an internal fuel filter leak (so it just returns to the fuel tank) or a fuel leak elsewhere.

By the way, be careful with diesel fuel lines, depending on the fuel pump (mechanical or electric) pressures range from 3,000-25,000 PSI maybe even higher!

Check the lines, and drain or replace fuel filters and let me know what you got.

Hope this helps you out.

Hard starting on a DIESEL


Check your fuel pump make sure you are getting enough fuel. If the fuel pump is not working properly and then you spray starting fluid and it runs, I would replace the fuel pump
