fuel pressure regulator install, with pictures

Would this be fine how I mounted my afpr??

I like it! Much niftier than mine, the cruise cables are in the way of the gauge

Are you running through the fuel rail in the opposite direction of stock?

Yes sir, the other way the fpr is way to close to the cam gears

Lol, i think this may be one of those "why the hell haven't we thought of that" moments.

HAHA well as long as your feeding from the the other side its looks fine.

im also happy to see you here on tuners instead of TR

I actually got the idea off my friends talon, he actually wants to switch it up though since he said one of the aluimuim fittings cracked from possible the weight of the regulator, but this could of been from a crappy cheap fitting, or a bad cast..Who knows, figured I'd try it out since it only happened to him once and its been fine every since..

I never seen it mounted on that side. I like them mounted on the firewall.

for each is own

This is not a good idea. You are effectively regulating the fuel pressure in the line before the injector rail. The idea of a Fuel pressure regulator is suppose to regulate the fuel in the fuel rail not the line before the rail.

It doesnt matter what side the FPR is on. As long as its on the opposite side as the feed line it still works the same way. OP, the setup looks nice.

I can't see clearly from the picture but if you reverse the fuel flow then i can see this would be just as effective. (fuel flowing in the fule rail from the timing side and coming out the transmission side)

I would mount it on the firewall. The vibration of the motor can cause strange things to happen. Non functioning gauge, vibrating parts loose, etc. As well as you listed, can break the fitting from the weight/vibration and can be dangerous.

You will most likely crack your fitting with a setup like this. The fuel rail is bolted straight to the head, so it receives direct vibration from the engine. Putting the heavy regulator on the rail with just the fitting will cause the connector a lot of stress, hence why your friends fitting cracked. And the regulator is just fine on the left side like that, fortunately the fuel rail is the least complicated part to understand in our cars, its just a hollowed out tube, doesn't matter which way the fuel runs through it.

As a sidenote though, like I said, people have encountered problems bolting their regulators straight up on the rail like that. Although, FFWD's fuel rail design uses it bolt-up:
FFWD Connection - Race Injuns That Will Freeze Your Brain
Probably because that is the mini FPR, less weight, and they are using a larger gauge NPT fitting as well.

^ Look how its mounted, pretty much on the fuel rail. Look at the OP's, he has 3 fittings total connecting, causing more stress, vs FFWD single an fitting.

Well, for some of us is not a good Idea.

For some others that are actually trimming the Front Cover to fit the regulator on the rail, this is a great idea and will have more clearance to mount it.

However, even me not going that rout, I do give props to the OP for bringing in that Idea..

 

[codeofdastreets]

well I happy I got a decent amount of input, Im going to start the car with it how it is, get the timing done, and brake the motor in..I can see it possibly cracking over a long period of time but not right away..
