I just completed my ITR swap and this is the only thing holding me up.

Ive went through two sets of seals now and am beyond frustrated. The POS Benen rail destroys the seals.

The bore is smooth, but I believe the hole for the injectors is not quite large enough. I am installing the injectors the same way I have numerous times before.

I put a light coat of oil on the top seals, carefully work them into the rail, then ease all four injectors into the intake manifold at once.

Im sure others have had the same problem, but a search only yielded one person asking the same question with no answers, and he seems to be having the opposite problem with the holes being too large.

Is there a solution (possibly a different seal to use?) or am I screwed and just need to get a different rail.

I cant go back to stock as I have already installed AN lines to an Aeromotive regulator, etc. etc.

 

What's the actual problem, they leak after you install the injectors into the manifold and tighten everything down? Or can you even get them into the fuel rail?

 

I would carefully ream out the holes slightly if they are too tight.Two friends also had issues with their fuel rails the fpr hole was not drilled into the rail causing issues with fuel delivery.Benen has horrible quality control and customer service for being so highly praised on here.

 

They leak after installing them, the seals are getting chewed up.

My FPR hole is the same way, its not drilled either. But for me its fine because I am running an Aeromotive regulator. I tried to put a smoother radius in the hole where you insert the injector as the stock rail is radiused much smoother than the Benen rail, but it just made things worse.

I already gave up and ordered a Skunk2 composite rail. This is my first time going with Benen and I am not impressed. I will not buy another part from Benen nor recommend them to someone else.

 

Same way I do it. Its hard to believe they get "chewed up" if you're doing it this way. Not that I dont believe you, but I guess I'd have to have the parts in front of me to truly understand and see this for myself. Post a picture of damaged seal after install?

 

I threw them in the trash. I assure you the rail was damaging the seals. They were getting pinched upon insertion which was cutting into the seals.

I compared the Benen rail to the stock rail. The Benen rail has a beveled edge where the stock rail has a nice smooth radius where you insert the injector.

 

and your crying over this and you have not had a light bulb go off to have them opened up a little bit more?

 

Perhaps you should read the thread in its entirety before you contribute with sarcasm.

 

My sarcasm is direct as well as relivant to your situation. I own the same fuel rail and have not had a problem with it at all. Perhaps you got a defective unit and should consolidate bennen industries with your problem...if you bought it directly from them. If not, and you bought it from an aftermarket company, then you know what to do.

If you DON'T know what to do, then id advise to retuen it if you have the reciept...if not, then I dunno wat to say

 

I also wasnt impressed with their quality and I dont really get the point of buying their stuff but I guess thats just me.The S2 rail will serve you better and I bet you have no issues with it either.

 

My reply was based on the fact that you suggested something that I had already done. I contacted the company that I purchased it from and they directed me to contact the manufacturer, I contacted Benen and they could give a rip unfortunately. After that I tried to make it work myself with no luck.

Ive heard both stories, many people have said they own one with no issues, many others state they are crap. I do not know if it is accurate, but I have read that Benen was bought out by Blox in the recent past. This would explain the differences in quality.


Trust me, its not just you. I hope you are right about the S2 rail, I have used numerous S2 parts in the past and have always been happy with them. I should have bought the S2 rail in the first place, thats what I get for trying to save some money.

 

These things are junk. I had the same issue not to mention the holes for the FPR are off by a mm or two. Its a $100 paperweight, what a waste. Poor designa and weak quality control to say the least. Benen FTL.
