Not at all..
For those reading this post, if one suspects no fuel on these type systems and they have no proper test tools, you can get a general idea of fuel at least reaching the engine if you just take the cap off the test port and push the valve in like on any bike tube...use a rag and if you get a decent presure squirt of fuel at that valve , you can assume you do have fuel pressure...a gauge will tell if it is to spec, but that quick test will tell you that at least you have something at the rail ....which is a good diagnostic start.
Specially if you are stuck somewhere...........................
