This is so sad, but I'm not really sure what to get for the fuel pressure gauge. I went to Autozone and they had a couple of packaged up gauges with lines and what not that looked like they were designed to hook up to a predetermined port on the fuel rail of certain cars, but none of them seemed to be designed to work with just a straight fuel line. I was thinking of just buying one and removing the stuff that hooks it up to a port, but I wasn't sure if that was going to work out all that well.

I think anything you can physically connect without leaking is fine. You could also mount it under the hood and use a webcam or pull your hood. :-)

You only need to watch it for a couple minutes, so it's no big deal. I have my doubts about your fuel regulator...

I went to swap the injectors to the 1.8s and found that one has a square connector rather than the rounded, bah. The guy says he is sending me the right one, but I'll probably pick up another full set from partsgroup.

I'm looking to get the BEGI AFPR.

Check with Joe, I think he doesn't run an rising rate regulator at all. Me neither, but it's different.

I swapped in the 1.8 injectors and that seems to have cured my lean condition (at least according to my NB O2 sensor). I did get the BEGI AFPR, but I haven't hooked it up yet since I don't have anything to measure the base fuel pressure.

I really do want to get something to measure the fuel pressure, but all the local stores don't seem to have anything that fits my application. The Napa had a gauge for non fuel injected cars. The Autozone has a kit that only seems applicable for domestic cars.

Would something like this work?

You'd think someone would know this. :-) I don't have one myself, but I'm sure summit if nowhere else would have it. All the ricer shops would sell them.

Several for <$20

When i worked at kragen, i believe we had a loan a tool with a fuel pressure gauge with all sorts of fittings.

Harv 06-12-2008 01:42 PM

I found one that fits inline for $30 that should hopefully work.

Hey Harv, did you sort this out?
after installing my new tony DP i came across the same problem.
when cruising at aprox 4000rpms with low boost, just touching the pedal slightly, goes over 14.1. :(
need to check the 02 clamp voltage, but i'm pretty sure it was set to .32v.

i'm running the 1.8 injectors, vortech fpr and stock pump. no issues with the greddy DP.

oh and also the new tony DP rubs the gearbox... very irritating noise!

Buy a Wideband, and Megasquirt. Quit playing with all the bandaids. Sorry dude...

mx5dude69 06-19-2008 04:24 AM

i have a wideband, and the ECU is going in next month or so...

^^ Which you're picking up on the way down to my house tonight, right? Or at least, over the weekend?

mx5dude69 06-20-2008 12:28 PM

O2 clamp set to high voltage. after setting it to .44v works like a charm.
rich across the board, the 1.8 injectors are doing their job too well. :)

You want to come dyno tune it for me? You think if I can't get the band-aids working that I will be able to make a Megasquirt work? I love how this is some people's idea of a solution. No no, don't try to make your existing setup work, buy a whole new setup that will give you new problems! Yay!

I was running the 1.6 injectors. Once I put the 1.8s in then it went back to rich.

Now my problem is the thing is hesitating and stalling. I'm thinking either plug wires or plugs or both. Have to check that today. Not sure if I should switch to a colder plug or not.
