Anyone know who makes the throttle body?
I found a basic fuel injection pump tester but it will not work on Bosch,CIS Jetronic, and GM Throttle body system.
heres the link
Fuel Pressure Tester & Fuel Injection Pump Tester

 

Motorcraft,
But I do not see the relation between the two.

 

If ours was made by Bosch,for example, I would not purchase the testor.

 

If your car is equipped with a Schrader style port on the fuel rail that tester should fit - pretty standard stuff. The reason for the exclusions you mentioned are they require banjo fittings and/or other adapters in order to connect. At <$20 I'd question the accuracy of the gauge - if you were just comparing pressure drops by means of an injector pulsator it would work. But, for the sake of argument, you have one of the many GM vehicles that absolutely will not start when the fuel pressure is below 53# and the gauge reads 49# don't be surprised if the fuel pump was not the culprit...

 

Thanks.
I'm a shadetree mechanic & want to use it on my Jags - 97 XK8 & 07 X Type.
I do wonder about the accuracy & quality though.

 

You have a DENSO system and that should work just fine.
