Curious on where to install a fuel pressure gauge on a 2g when using the stock fpr it bolts directly to the fuel rail so no way to put my T barb with my sending unit in between.

you could tap the rail 1/8 NPT or get an aftermarket rail that already has a 1/8 npt tap. better of just getting a cheap 0-5v transducer and logging rather than a gauge though..........way more useful. Its nice to be able to confirm that fuel pressure is rising one to one as you review logs
Ok so maybe I was confused at first. The fuel pressure gauge doesnt have to be on the feed side? It can also be on the return side?You could get a banjo bolt with a 1/8 npt adapter for your fuel filter (located against the fire wall). That will not require any drilling/tapping or modifications. Just remove the bolt and replace with the gauge adapter. Easiest way in my opinion.You must be logged in to view this image or video.
As most people said, it's a waste of time to do this but that fuel filter banjo bolt is your best way to do it.Ok so maybe I was confused at first. The fuel pressure gauge doesnt have to be on the feed side? It can also be on the return side?
No. It has to be on the feed side.Ok so maybe I was confused at first. The fuel pressure gauge doesnt have to be on the feed side? It can also be on the return side?

Has to be before the regulator. Select the spot you will tap with the rail installed and all components in place to make sure it will not obstruct anything if you choose this method.
These rails are stupid cheap and a dime a dozen so no reason to be scared about tapping........
Ive got about a dozen of these rails so their value to me may not be what it is to others.
That fitting is the way to go if you only have one rail or don't trust your abilities.
Hope youve changed your fuel filter before....... or the fitting may not necessarily be the easier route....as far as "best"........thats just a silly word to use here really. Both methods work great. Choose your path.
Ok I just figured it would go through the FPR first without knowing much about it that would seem logical. I haven't changed anything, so in that case my answer is solved. I can just place my T fitting between the filter and rail then screw my sending unit it and then wire up the gauge and call it a day.Feed is left. Return goes through fpr unless you’ve changed something.
Not sure how it is a lot of work? I literally just cut my fuel feed line in half and install my T sending unit barb, it took 5 minutes. Ran all my wiring and got the gauge hooked up.I would not recommend drilling and tapping the fuel rail. If you mess up you have a potential bad day coming. If you really want to install a gauge so that you can look at it (thats about all you will do running thr stock fpr) then do it at the feed before the rail. If you have a male to male fitting you could place it on the feed with a couple clamps. Again this seems like a lot of work for a gauge without adjustment but not my monkey
