Before I begin, let me start by saying I know. I KNOW that there are probably a dozen freakin threads related to this and I should go search them out. Well, I already did for 3 1/2 hrs. this afternoon and I found nothing, so.....


Does this look like the correct location for the sending unit on a defi fuel pressure gauge?

I can't tell if the picture is going to show up or not, so I'll just paste the link.

If it is the correct location, it's only reading around 10 lbs. at start-up and drops to 5 after about 30 seconds and then stays constant at 5 lbs. Does anyone have any idea what kind of fuel pressure a 2006 STi should be running? Should it make any difference that I have switched to a 255 lph Walbro pump?

Or, if this is not the correct location, does anyone have a better suggestion for a location?

Any help is greatly appreciated. And I'll give you a cookie.

Or could the low reading be due to the fact that I tapped into one of two lines that supply fuel and I'm just not getting a full reading because of that? Anyone?

Nevermind. for those who may be curious, the top line in the pic is the feed line, the bottom is the return and both are high pressure fittings.
