i know the vortech FPR (same as the B&M 'fuel flow modifier') require you to cut your stock FPR and mount the adjustment assembly ...does the stock toyota regulator look like it would work with a similar unit ?

I tried the B&M AFPR, it doesnt fit the 4AFE Stock FPR.

Hm, that's interesting, but I agree that the toyota regulator won't work like that.

I just dished out 120 bucks and bought an aeromotive piece. It's very very very nice, can't get any better.

closer to $300 with fittings, hose, buying a hose end because one broke, etc.
but yeah, i love it.

If you follow this write up, it will cost $236

Here's my wicked how-to picture on installing an FPR:

One thing to note on his diagram. I followed it exactly, however found out one thing. There are no 12X1.25 threads in either the 5sfe or 4afe fuel rail. You'll need to tap it out, and that size is perfect for it. Other than that, it's perfect.

Where are you guys mounting your regulators? Do you find pressure right on the regulator or upstream somewhere?

I've got a spare 4AFE rail and injectors if anyone is interested...

Snafu: good to know, thanks!

hooligan: I mounted mine on the strut brace with a plate and some bracket things. I'm not 100% satisfied with how it is done at the moment, but it will do until I do some welding on there or something like that...

I took pressure right from the FPR. There's a screw right on the front of it that will adapt to most pressure gauges.

yea i got a 90* 1/4" NPT to -6 AN cut/welded on the rail.
and i used that as a guide, but bought 6 ft of -6 AN hose and used braided hose and an -AN fitting for the return. i also had to buy 2 -4 AN 90* ends because the first one broke during installation...wtf. so thats why mine cost a little more.

I mounted my FPR on the firewall, just to the left of the intake manifold. I found it would have been easier to use a 90 degree elbow right off the left side of the regulator, that way you can easily loop it around to the fuel rail.
