better place to tap for a fuel pressure gauge?

[SpyderDSM]

Saw a thread from 2004 about tapping for a fuel pressure gauge by drilling a hole in the fuel rail.. is there a better way to do this by any chance?

i need to tap a sender NPT 1/8"

thanks in advance guys

AFPRs often have a spot. Maybe time for an upgrade?

yes agree with AFPR pressure port! why do you wanna know your fuel pressure until you have upgraded to an aftermarket pressure regulator?? AFPR comes with a pressure port!

I second that motion

+3. That's the only way I would do a FP gauge as well. Tapping into a stock part that COULD leak is just going to end bad in my mind. Just make sure you get one that has a 1:1 raising ratio.

Another way is a thing called a gauge adapter (10th item down). This usually screws in/on to your fuel filter and then the feed line goes onto it.
AN PLUMBING.COM Earls performance products, Hose ends Hose,Adapters, fittings

These are typically used if you have an in-cabin fuel pressure gauge and you need a SS feed line. Otherwise, AFPR is the best spot.

you could also get a B&M fuel pressure gauge kit. I think JNZtuning.com has them. It is a simple gauge that goes ona fitting that goes between the top of your fuel filter and the hose to your fuel rail

yah i like the one that screw onto the top of the fuel filter.

I'm thinking he wants to check fuel pressure maybe because he's having some problems with the way the car is running and not for performance... just my guess since he hasn't responded since his question.

I've had consistant problems with the same thing, now that it's fixed id rather not have a logger in the car all the time haha but thanks for all the imput, ill ###### end up with the afpr upgrade.

If you're planning on upgrading your FPR or filter or stock fuel lines, you can (as mentioned) put the sender in the port provided on the AFPR. But since you'd be replacing all the lines and having to attach the AN fittings to that new fuel line, you can add a fitting anywhere you want and put the sender wherever you want to. Some put it between the filter and rail, but that's "upwind" of the pressure drops across the injetors. I've thought about keeping the normal under-hood gauge directly on the AFPR, but adding a tee and sender between the rail and AFPR so I can run an electrical fuel pressure gauge in the cabin.

The link below mentions the sender plumbing:

And here's what I'm getting ready to buy:
STM SENDING UNIT TO FUEL RAIL KIT | 90-99 DSM
and
STM FPR -6AN FUEL RETURN KIT - SHADOW SERIES | 90-99 DSM

the AFPR is the best way to go IMO

+1 for AFPR

So you plan on doing what's described in that link to keep the stock fuel pressure sender in that location and then putting an electric fuel pressure gauge on one of the ports of the AFPR? This is a damn good idea. I will probably do the same since I've been wanting to redo my fuel setup. And I have that vent gauge mount from MachV so I'll put an AEM one there. Thanks for the idea kenamond.
