How to measure fuel pressure??

[rbutton]

Can someone point me to a kit I can buy so I can hook-up a fuel pressure gauge to my 7M-GE? Extra points for something inexpensive.

Suspect I have a leaking injector (have trouble with warm starts) and want to verify before sending off the injectors for cleaning/tuning.

discussed here^^


drill and tap the stock bolt, or order the actron one for a kit. Also, this kit should come with the right size bolt:
(12x1.25 according to the above thread, I havent messed with it myself)

Thanks for the ideas! I searched the forum and couldn't find anything.

I happen to have a pressure kit from Harbor Freight that has just the right things I need. There is a short 6" hose with a 6.0 x 1.0 mm threaded connection on one side and a schrader valve on the other side. Just need to drill out and tap the cold start banjo bolt with a 6.0 x 1.0mm tap and it'll be good to go.

One problem - the stock banjo bolt seems to be made out of some pretty hard stuff. Has that chrome steel look to it. Can't even get a small bit to bite in. I'm guessing it's going to be tough/impossible to tap.

Suggestions? Looks like I might have to just buy a regular steel banjo bolt.

Well, I didn't want to burn through a bunch of drill bits and break a tap, so I bought one of these -

and a 1/8" NPT to 3/16" hose barb that will work perfectly with the hose and meter I have in my Harbor Freight kit. Once I get everything I'll let you know how it goes.

All this because Toyota didn't see the need to have a Schrader valve.
