SOURCE: Fuel line connections coming from fuel pump on 1999 Chevy S10 4cy

Id say the fastest way to find out which line is the pressure side is to put both lines into a bucket and turn the key on for a second. the pressure line will have fuel coming out of it...other is the return line.

SOURCE: 98 Expedition coolant leak top back of engin

Sorry im late with this,i couldnt seem to log on....The answer to your question is YES,there is a steel line under the intake with a short piece of rubber line attached to it and you can just about see it from the front of the intake with a light,it can leak and cause coolant to run off the back of the engine,The intake gasket set alone is about $40.00 and i dont know about the rubber line,i have seen it physically but havent changed one yet.Note the date of manufactor just incase,i bought an intake set for a 99 and the engine design was changed half way through...its not too hard to pull off the intake and re-install,you will need a 7mm socket for the coil packs,8mm socket for the fuel rail bolts and lower intake bolts and power steering bracket bolts and throttle bracket bolts,10mm socket for the intake bolts and alternator bolts and egr valve,and a large cresant wrench for the exhaust tube thats connected to the egr valve,flat screw driver for the air cleaner...and plenty of extensions with a swivel to be able to get to the back bolts of the intake....just incase you do it yourself this info could make it easier to gather tools.Its about a 3 1\2 to 4 hour job start to finish for the first time doing it,includes cleaning everything..Good luck

You have to replace the connector. The parts stores have a repair kit for this.

SOURCE: I have a 1999 taurus 3.0 v6. The trans cooler line

You can buy a snap in replacement end that can be bent and attached to 3/8 th's fuel line and by pass the rotted metal line. I have been doing transmissions Since 1981, and have the same rotted lines on my 01 Windstar. I just went to all hose except the line into trans and into radiator. double clamp the hose on the lines and save a lot of money. make sure you sip tie the hose so it is out of the way and check your trans fuel level when you are done. Let it get hot in park and running when you check the level on the stick.

Hope this helps.

Leaking fuel pump


If the fuel is leaking into the car you will need the replace the seal on the top on the pump assembly not the seals on the pump itself but before changing the seal just double check the fuel lines are tight and the leak is actually from the fuel splashing out of the tank. The seal your after is referred to as the pump assembly oring ( big rubber oring around the top of the assembly a smear of silcone can be used as a temporary fix but erge you to get it fix properly as soon as possible and fuel fumes in the cabin can be extremely deadly)
Hope this helps

My husband has a 2004 Chrysler Intrepid. On June 21, 2011 the engine light came on and we took it took it to the garage . The mechanic replaced the intake gasket for a vaccum leak , well since then it...


Take it back and he will fix it, maybe a o-ring where the fuel line connects to the fuel rail or if he removed the injectors, then a o-ring maybe pinched, loose fuel line fitting. something minor, but dangerous, can catch fire real easy, I would have it towed to be safe.

I have a leak on one of the metal fuel lines leading to the engine. are the lines threaded with o rings?


the fuel lines all have a rubber 0 ring for sealing the fuel pressure from leaking,these 0 rings a designed for use with fuel and won`t go bad when in contact with fuel.the 0 rings are fitted on the fuel lines near the end of the lines.

I have vacum leak on top left side of my engine as if u were standing on the passengers side of the car its a hose that goes in between the 4th and 6th fuel injector, right underneath were the fuel lines...


If the hose itself is leaking replace the hose. If its the plastic fitting, remove the hose, remove the plastic fitting from the intake (should clip in), replace the o-ring on the fitting, reinstall the fitting into the intake, and install the hose onto the fitting.

Injectors for 1989 honda accord removing and installing


Detach the cable from the negative battery terminal (if you have an anti-theft radio, make sure you have the code to reactivate it.).
Relieve the fuel pressure (take the gas cap off, and loosen service bolt at the top of the fuel filter; you will need two wrenches for that, on to hold the fitting and the other to loosen the nut; make sure you have a towel or something to catch the gas spill). You could, instead, just SLOWLY loosen the pressure line at the right end of the fuel rail (facing the car).
Remove the air cleaner assembly (take the top off, take out the filter, detach all hoses, take out retaining bolts, and remove).
Unplug the injector connectors (CAREFULLY detach the clips first; just pry them back out of their notches; try not to pop them off and drop one, they are hard to find once dropped).
Detach the vacuum hose and fuel return hose from the fuel pressure regulator (left end of the fuel rail, if you are facing the vehicle)
Detach the two ground cables from the intake manifold (in the middle, under one nut)
Detach the fuel lines (already did left one; detach the pressure line at the right end of the fuel rail).
Remove the mounting nuts (four) and detach the fuel rail and injectors from the intake manifold.
Remove the injectors from the fuel rail and remove and discard the seal rings (top and bottom; the second ring down on the top is the cushion ring and does not need to be replaced, but it is recommended. Most kits contain them)
Coat the new o-rings with fresh oil and slip them on the injectors (or, if you are replacing the injectors they probably came with o-rings on them. Just coat them with oil)
Place each injector into its corresponding bore in the fuel rail (doesn’t matter which is which if you are replacing them all).
Coat each new bottom seal with oil and press it into the injector bores in the intake manifold.
Install the injector and fuel rail assembly on the intake manifold. Make sure the centerline of the electrical connector on each injector is aligned with its corresponding mark on the intake manifold (little arrows, I think). Tighten the fuel rail nuts to the specified torque (17 lbs)
Reverse removal procedure for the rest.
After all is done, turn the ignition on, but do not start the car. This will build up pressure in your fuel lines. Do that two or three times, then check to see if you have any leakage around the injector, or other fittings, before you start the car.
Then you’re done.
Hope this gets you through it.

How do I remove a fuel injector in my 1988 chrysler new yorker?


There is what is called a fuel rail. The fuel injector fits in between the fuel rail and the intake of the engine. If you look around the rail you will find a few bolts (usually 10mm) holding the rail in place. remove the rail bolts and gently pry up the rail. The injectors fit into each one with an o-ring sealing each side. Watch because sometimes the o-ring will stay in the rail or intake and you want to remove them before trying to put the new injector into it. If you have a little petroleum jelly, put a small amount on the o-ring before inserting it in the rail and intake. Line up all the injectors with the rail and intake and gently push them in. When all are lined up you can lightly tap the rail with a hammer, LIGHTLY tap it into place and reinstall the retaining bolts.

Hope this helps.
