pressure test line comming from fuel tank,one of two ways,1.disconect line from fuel filter on side where fuel line connects from fuel tank,if pressure 26psi to 35psi reconnect line to filter and check your line on other side of filter if pressure holds your fuel pump and fuel filter are ok,the other way is to disconnect inlet line from tank to fuel regulator and check your fuel pressure,the only thing with this method is if your fuel filter is clogging or clogged you will not get an accurate fuel psi.you can also check your fuel regulator,you fuses,or your relays to anything that has to do with your,depending on what type of car you have
loosen the fuel line and if fuel squirts forcefully out the pump should be good,but it's really hard to tell pressure wise if you have fuel injectors they need a specific pressure to run.
either go to sumone who already has a fuel pressure tester or purchase one of your own and hook it to the fuel line and test it!
Car won't start. Aslo check if there is pressure In the fuel line
you hook up a fuel pressure guage to it to check the fuel pressure
The larger line is the pressure line, the smaller line is return.
Well, i suppose if your injectors are using all of the fuel (super rare) then there would be no fuel coming back to the return fuel line. However, since you say there is NO fuel pressure, I would check out the fuel pressure regulators and the vacuum lines connected to them. The pressure regulators are located on the top of the engine and are directly in line to the fuel line. They are connected between the fuel rail (where all the injectors are fed from) and the metal fuel rail on top.
There is a special adapter that is needed, you remove the fuel line to the fuel rail, install the special adapter and then install the fuel pressure gauge to the adapter and reinstall the fuel line to the adapter.
Restricted fuel return line or a faulty fuel pressure regulator.
Could YOU tell me where the fuel pressure regulator is on a 95 astro van
It doesn't have a vacuum line attached to the fuel pressure regulator.
There is a slight amount of pressure on the line after shutdown. To relieve the pressure remove the gas cap, and look for a Schroeder valve on the fuel rail. If there is none and you want to change the fuel filter, just be prepared for a slight spray of fuel when you disconnect the fuel line. A rag over the connection when you disconnect the line will prevent a spray of fuel.There is a slight amount of pressure on the line after shutdown.

With the engine running, remove the fuse or the relay for the fuel pump. The engine will stall soon and the fuel line won't have any pressure left.
There's not 1. They sell a fuel pressure Gauge kit that goes in the line up by the throttle body when you remove the fuel line from it. Nother words you will have to splice into the fuel line.
It depends entirely on the year, make and model on how and where you can check fuel pressure. In order to officially and properly check the fuel pressure you will need a fuel pressure gauge and a set of adapters and fittings that typically come in a relatively expensive kit.Most GM, Ford and Chrysler engines will have a Schrader valve located on the pressure side of the fuel line, usually near the fuel rail that houses the injectors. If the fuel line has one of these valves then you can screw on a fitting that attaches to a fuel pressure gauge, crank the engine and see the fuel pressure. If the vehicle does not have one of these valves then a specific, special fitting that comes with part of the fuel pressure tester kit needs to be installed in line on the pressure side of the fuel lines somewhere where the line can be disconnected.
With vacuum line (from fuel pressure regulator) OFF and pinched , pressure should be between 47-54 psi. With vacuum line ON fuel pressure egulator, pressure should be between 38-46 psi.
The vehicle does this on its own with a vacuum operated fuel pressure regulator.
With the aid of adapters, you can "T" into the fuel line at the fuel filter and attach a fuel pressure gauge.
Find the fuel line or where the fuel injectors are and fallow the fuel line they are connected to and at some point you will find a connection much like a tire connection that is where you will do a fuel pressure test from
the fuel return line is on your fuel rail. it is part of the Pressure regulator assembly. Please view my Bio for access to my Saturn help site. in the fuel folder, go to Fuel pressure lines. the return line is highlited in green for you
there is always fuel pressure even the car is on or not, u will need to release fuel pressure before doing any thing in the fuel line
On the side of the throttle body where the fuel feel line and the fuel return line go in there is another spot for a hose to go in this is for the fuel pressure gauge you must hook a fuel like into this then to your Gage fuel pressure at idle should be 14-16 psi.
