Cheap Fuel Injection Pressure Gage

[JonesVWs@aol.com]

A few months ago I wrote up a thread on a cheap fuel injection pressure gage
for the type 2 list. I have seen alot of letters from the 68-on type 3 folks
who are asking about how to check thier injection pressure. 

If you want a real cheap solution...here goes:

Go down to your local hardware store and pick up a 100psi water pressure
gage. These are designed to mount on your home plumbing to check your water
pressure. They go for about $6 and usually have a 1/8" or 1/4" NPT male
thread on the end. Using adapters to get to a 5/16 inch hase barb, connect
the whole unit to about 2 feet of good high pressure fuel line. Attach this
line to the adapter on the fuel injection runner (I think it's the one on the
left side that has the plug for testing). Just remove it and clamp the hose
over the fitting. Mount the gage in you engine compartment where you can see
it when the access panel is removed. It should read in the 28-30 psi range. 

I leave mine attached permanently...I figure if your running 25 year old FI,
it's a good idea to have it there when the FI starts acting up. I have a '74
914 2.0 that has had the same gage on it for 7 years. Now all my FI VW's have
these gages....for about $10 each.

Try it, you'll like it.
