Does the RB26DETT Fuel Rail fit the Rb20DET?It should be the same thing seeing that the injectors are similar, but the only thing that makes me unsure is that the intake manifold on the Rb26 is different.The reason I'm asking is because I have a Aeromotive FPR that I want to hook up, but the FPR has AN fitting and there are none on the stock fuel rail.

How did everyone else hook up their Adjustable FPR?If anyone has any pics it would help too.

the rb26 doesnt have an AN fitting on the rail either, so that wouldn't solve the problem.

i used the nismo fpr- it is a direct swap.

but if you wanted to make an AN fitting on the rail, you can also do that by drilling out the rail's original FPR hole, tapping it to metric (probably easiest), then getting a fitting to convert it to AN.

Yeah,I know that someone makes a Aluminum Fuel rail for the RB26 so I was going to look into getting that.How much was the nismo FPR?Do you have a Rb20 or a Rb25?

Yeah I got my nismo fpr from phase2motortrend.com. It was pretty cheap and its a simple bolt on affair but you will need a fuel pressure gauge so you can know what pressure you are running. I just have a simple one I got from a performance shop and went to home depot for some fittings and barbs to tie it into the fuel line in the engine bay. Get a nismo save yourself the headache. Its the difference between pulling your rail and probably your intake manifold and drilling it out and tapping it and buying the correct fittings. That will be a pain. I have a rb20. I dont remember whether the nismo fpr a or b is the proper one to get. ~ANDREW~

I am running an aeromotive fpr. I taped the end of the rail and ran braided fuel line so I could remote mount it to the side of my engine bay. It made my swap look cleaner.

Cheapest place for the non-universal NISMO FPR that I found (in stock) was http://performancenissanparts....id=96

105.95 plus shipping. I think my total shipped to GA was $112 or something.

They also have the Universal NISMO FPR for the same price. It took me about 5 days to get the item from Cali.

Yeah definetly post up some picsI already bought the FPR so I'll probably just do what the other guys did and drill and tap the stock rail

Here are some pics of my fuel setup... Dont mind the filthy engine bay...

All of the lines are -6 an and I used aeroquip fittings I got from jegs and I bought the fuel filter with steel an fittings for 18 shipped from a guy on honda-tech. To mount the filter I just used the stock mount and turned it sideways. Also the fpr is an Aeromotive.I just used oem hose clamps to hold the braided lines onto the stock feed/return hard lines.Blurry pic... this is a pic of one of the fittings I had welded on the rail for me in place of the stock fpr's. Its a steel weld fitting -6 an and I got it from chassisshop.com

The entire setup including the fpr probably cost me around 250 give or take a few bucks... Let me know if you need any other info.

Just remove your stock fpr, and drill and tap the hole to a standard size (whatever is closest). Then just get a AN strandard-to-AN fitting, several hose ends, and -6AN or -8AN line, and you are done.
