Hi all. I think I may have a problem with my fuel pressure, so I need to get a fuel pressure gauge to do some troubleshooting. My Bentley manual says that the Volvo part number is 5011, but when I talked to the dealer, he had no idea what that number was. I'm not sure that I even want to get one from the dealer because I thought that I read somewhere that the gauge and fittings cost about $600. Way too much. I've been to my local auto stores and the only gauges they have require the schraeder valve, which the Volvo (at least my 240DL) doesn't have.

Any of you out there come up with a good home brew solution, or some aftermarket source?

thanks

If you have a CIS or L- or K-Jetronic FI system, the real problem is splicing the pressure gauge into the system. There are banjo fittings with longer bolts that work best to patch into the injection log/rail or fuel supply to the fuel distributor (the big thing with four injection lines going to the individual injectors on CIS injection).

You might get an individual fitting from a Snap-On truck guy or try Harbor Freight's website for an injection test kit or adaptor set.

The Schrader-type valve setup is the way to go for GM cars, but won't help you on Volvos (or Saabs or BMW for that matter).

if you just want a gauge...go to a "real" parts house...NAPA...they carry fuel pressure gauges...it where all the race car guys get em....they also sell hour meters...(which is a better way to measure the lifespane on any engine)they also sell a fuel pressure test kit....$30 buck range...
