Thanks :tup:

That is a legit question and I need to add that to my fuel pump modification guide.

I overlook it easily because I am, naturally, entirely accustomed to return fuel systems rather than pushing the stock one.

I believe that you will need to drill the stock regulator. Its a delicate procedure since it is not removable, so take great care.

The gauge adapter will fit with the Stillen stuff, but you have to bend the fuel rail inlet tube a few degrees to angle the attachment point a little. I understand that it is very tight on that side of the engine with the new intake manifold and both throttles on that side.

its not that tight. just leave it laying there til you get the intake on and the pipe going to throttle bodies. once all that it installed it just needs a little tweek.

Mine were. Had to push it down pretty hard just to get the silicone coupling on. After that there wasn't room to slide a metal gear clamp between the fuel line and coupling. I'll see how much I can bend the metal tube without kinking it and make some clearance.

What is a good basic Fuel Pressure gauge I can hook up to my stock rails?

If you want to go basic just add the optional mini gauge... or use the NPT port to add a sensor for your own gauge.

That looks perfect!... but doesn't seem like it'll work with the damn Stillen Intake Plenum/Intake Charge Pipe. Though in a couple of weeks I'll be switching to TopgunZ's A2A kit.

It does fit the stillen setup but it requires you to tweak/bend the fuel rail inlet tube some degrees to clock the attachment point. Someone sent me pics yesterday I will post.

Yeah, it will fit, but like phunk said you need to twist the hard tube. Which is easily done.

You guys saying it needs to bent even more? Cause I've already bent it as per Stillen's instructions to get the Stillen charge pipe to fit.

You would have to just make adjustment as necessary by examining the exact conflict between 2 components fighting over space. I have not looked over the Stillen instructions but if they dont have you bend it enough to fit the fuel line when raised up an inch, then it would need to be bent more until it did in order to fit this type of spacer.

In the example shown here, the gauge and fitting end up at a bit of an angle. This may be unacceptable if someone wishes for the gauge to point straight forward.

Referencing that picture, I'd have to put a 45 in between the tap and the gauge. I assume that wouldn't be enough to affect an accurate pressure reading hey?

In a perfect world what I'd really like to do is run an 8" line or so from the tap and make a mount for the gauge using the two side by side bolt holes on top of the timing cover for the pressure gauge. Not sure how much that would affect readings or not. Being in the neighbourhood of 60 psi I doubt it would make much difference. Easy enough to do a comparison and test it out I suppose.

You can remote mount the gauge and I wouldn't expect the reading to be effected.

Perfect. It this was 6-9 psi like a carb I can see it making a difference but parts jockeys at two different speed shops the other day said it would, so figured I'd find out the actual answer from someone in the know before piecing it together. Darn thing like $100 in fittings hose and gauge just for that little bit lol

I've got a bit of a mess of stuff right in that area though so to even read it easily I need to move it over.

Alright, pulled the trigger and ordered one. Might get here around same time as the A2A kit and I'll just put them on at the same time. The main fouling point seems to be the TB plug, but factoring in height with this thing, might start fouling on the charge pipe. I'll figure something out I hope.
