I need help finding a FPR

I'm getting closer to gettin the BiTrouble's engine in. Once in, I need to wire up MSII and connect the fuel supply. Since my car was originally carb - the fuel system needs to be changed. Luckily the FPR on there has a return.

I need assistance find a FPR. I'm not going to go out and spend $100+ on an Aeromotive FPR. The cash just isn't there. Ideally I can find a cheap OEM FPR to use.

That is the OEM EFI setup. I don't have the FPR or the hoses that go form the fuel rail fitting to the FPR.

First, the factory FPR has two inlets on it - I don't see a technical reason why I couldn't Tee the lines coming off the Fuel rail and use a more conventional FPR - anyone have a differing opinion?

Second, does anyone know of an OEM FPR that uses hose barbs - I need to convert from the -4 fitting.

Third, has anyone used those cheap FPR on eBay - the "0-140 PSI with gauge" - I think I'd rather use an OEM one though.

Fourth, anyone have any other suggestions? Sorry if I'm rambling - running on a couple of hours of sleep.

I've heard of guys using a Nisson FPR when MS'ing classic Volvos' It's a little different being an I-4. Does it have to be a 4-port and can the output port be replaced with a T fitting?

Would a very slightly used $85 Aeromotive be acceptable?

I've used the Ebay ones before and my car didn't burn to the ground.

Sadly even $85 is out of my budget. The $25-$30 ebay ones are probably my choice for new - unless I can find an OEM one at PnP I can get for $1.

Is the OEM regulator static or does it go up a bit with boost?

The rate is static. I've confused myself talking about FPR with people before (or they've confused me)

Fuel pressure is always X psi above manifold pressure. X psi is constant. Not like an old rising rate FPR.

Ok so it's static base pressure, rising at 1:1 with manifold pressure.

That should give you something to look for in the junkyards. I know the FPR on the 88-92 turbo MX6/Probes is the same way, but you might run into flange issues. It mounts directly into the fuel rail.

Yea, thats my big issue. I need to find something that has hose barbs. But if you've had success with an eBay one - I may go that route.

That's probably your only hope of finding something that will work on a short notice.

I have a spare KL unit, but again, that mounts directly into the rail.

Dodge 2.2 turbo

Should be easily junkyardable I would think.

Volvo used a similar one. Pretty standard Bosch unit. Volvo runs at 45psi.

Dodge runs at 55psi.

Both rise at 1:1 ratio based on pressure in the intake.

The wealth of knowledge here continues to astound me.

Don't all the Volvo ones bolt to the fuel rail with an o-ring?
