Does anyone have pics and or instructios on doit yourself preasure test for 2nd gen.( fuel preasure)

To check fuel pressure on 12 valve:

I drill and tap the top of the injection pump banjo bolt to 1/8'' pipe
thread, then install a male x female 1/8'' needle valve with 1/8'' tubing
compression fitting in it. Boost gauge or oil pressure tubing pushed
though some 1/4'' tubing to protect against cuts and kinks to the gauge.
For a gauge you can use a fuel, boost or water pressure gauge, for a 12
valve it must be at least 40 psi. I use rear connected, liquid filled,
stainless water pressure gauges and make my own mount. They have no
lighting but it's not a gauge you need to look at all the time. They can
be mounted low for the same reason. Use no Teflon tape, it doesn't work
with diesel. Instead use anti-seize or Permatex #2. Remember you are
working on the clean side of the filter, keep everything spotless.
Compression fittings with a ferrule that slips over the tubing will leak
if overtightened, finger tight with one half turn of a wrench is plenty.
The ferrule should be replaced if the fitting is ever removed.
If you can tap your manifold for a pyro tapping the banjo bolt is a piece
of cake. Just drill from the inside to keep the hole straight and tap from
the outside. You can also connect to the bleed screw on top of your fuel
filter with the appropriate adapter to tubing if you don't want to tap.
The adaptor is available from TST for $25 they say it is only for temporary use though http://www.tstproducts.com/service_tools_trial.htm . After the install start your
engine with the needle valve closed then open it slowly till someone in
the cab signals you that it's just reading pressure. If you tighten down
the packing nut under the valve handle the setting can't move. The valve
will control pulsation and buzzing and can also be shut down in the
unlikely event that you have a leak. Without a valve to restrict the flow
the gauge will pulsate so badly that you won't be able to read it in the
short time before it self destructs.

Parts list; 1/8'' needle valve - $2.50 from the hardware store, plastic
oil pressure tubing kit that comes with the compression fittings - under $10
from an auto parts store. 1/4'' tubing for protective sleeve - less than $2.
Gauge is your choice and may come with tubing. The water pressure gauges I
use cost less than $10, bringing the total cost to less than $25 and a
couple hours of your time.
I have several gauges that have been in service for over 5 years with zero
problems though you may have occasionally close the needle valve a bit
more if the gauge starts pulsating. If you don't feel like tapping your banjo bolt I can supply one, just PM me.

can you use one of the oversized tapped bano's that geno's, piers, and wildcat sell for the 24v?

caca

Sure can. Set up will be about he same as above except you will only need a 30 psi gauge for a 24.

WHOOPS!!!
Palmetto, I misread your question. The banjos everyone sells for the 24 valves are a different size. I don't know anyone who sells them, maybe infidel.

I was thinking you were asking if the same procedure could be used for a 24 valve as 12.

that's pretty good infidel. how'd you get that pic ?

that's the pic of MY setup in MY truck that you copied and pasted from the tdr website !

looks like you took the text from one of illflem's posts over there.

good luck. bill fleming also supplies the tapped banjo bolts. $25. nice setup.

except i used 1/4" tube with slip no leak connectors.

olivmatt

infidel? is that you bill.? you old dog.......i love my set up....you did a great job.

olivmatt

infidel,

i can't get my pm's....something's wrong with this web site. just email me.

i have more pics of your fuel pressure set up if needed. works perfectly. thanks.
