Is it installed and not leaking? (I mean professional products) sorry...

LOL I tried the cheap road, now it's a $200 lesson minus however much I manage to sell it. It's leaking at the last 2 injectors towards the firewall. Well, I think that's where it's coming from, hard to tell when I have to power the pump at the same time lol... Could also be the cheap red fake AN fittings?

Thx

Ouch, man. I've been eyeballing the PP spyder intake and fuel rails like you have on eBay. Yesterday, I googled reviews on it and there were several threads on Corral that came up where people were taking them off due to poor fitment, etc. hmmmm....

Edit - Just rechecked and didn't find anything bad about the fuel rails. Everyone said they worked great. There were a few threads on here about them. Maybe try new AN fittings?

Yeah, maybe I overtightened the AN fittings at the rear? The nuts on the "bridge" pipe don't move anymore, they are stuck to the piece of pipe (hard to explain). But all the AN fittings I put on otherwise (Russell) don't leak at all, even the autometer AN4 fitting for the fuel pressure gauge. It's not leaking at the NPT fitting, that's for sure. I used the recommended thread sealant.

I took off the rails and they look fine, not even a scratch anywhere. As for reviews, all I've heard so about this rail leaking was at the fuel regulator. Mine doesn't leak there. I think if you don't put it on right, the first o-ring is easy to miss. Oh well, I'll make my own bridge piece sometime this week and test again.

Otherwise the rails install easily, it doesn't rub on the distributor, although you do need to remove the plastic cup (below the cap) to get the rail installed. I also don't like the idea of phillips screws to hold down the regulator and brackets - but that's an easy fix.

I went through the same thing, had to replace all the fittings because of all the leaks, then it worked fine. The ones supplied were absolute garbage!

we've probably replaced about 90% of the fittings on the fuel system of the race car over the last few years. fuel is hard on the O rings. if you get them and replace the fittings dont go cheap!

Did you ever find the leak and fix it for sure? Did you buy other fittings? I just bought these rails and now I am concerned about what I bought. Maybe I should have bought the aeromotive. That was three times the price
