my fuel pressure gauge just started acting wierd all of the sudden. when iddeling, it sits around 12-13(normal). then when i go to take off it spikes to around 17, and then down to 8-10 where it usually sits when i drive. its still working normal other than the initial spike when i take off. theres no leaks on the fuel rail or return or pump. Confused??

gotta go back to 5th grade spelling class first haha

 

Is it a mechanical or electric gauge?

 

what brand gauges

 

electrical by glow shift.

 

I'd try another gauge, even if it is just a test hose and a mechanical gauge.

 

thats what i was kinda wondering if maybe the sending unit started to go bad

 

Glowshift seem to have a reputation for a lack of quality.

 

they were good in there import scene or so i was told.. but then again maybe not

 

From what I can tell, they haven't found a more cost efficient way to keep quality. The price reflects their quality.

 

ya i could see that. i havent seen an issue with my egt turbo or tranny tho. sending units i know are pricy and this one wasnt.. theres the cost to quality
