Ok im in the plans on doing a quick update on my fueling.
Two quick questions.
Im somehow in a hurry because ll have to get to my tuner on athens (400 miles) before a new COVID lockdown occurs...
I found the holley both localy and really cheap. Like half the price of a A1000...
Also the AEM FUEL RAIL the classic one again localy and very cheap.

1) Anyone used the holley FPR? I know holley is respected company but you never know thats why im asking.

2) The aem fuel rail inlet is -6an fitting if im not mistaken. The deal is ill be changing the feed like all the way to the tank in like 4-5 months from now all along with the awd project.
I was planing on doing a -8an feed line like everybody seems to like to run. I plan on hitting 700 hp in 2021. Will ill be able to hit that on -6an feed line, maybe i dont even need a 8an feed line at the end?
Isnt it counter productive to do -8an feed and go down to 6an on the fuel rail inlet?
Id get a golden eagle or a radium fuel rail that both seem to have -8an feed holes but theyll be here the sooner like 20 to 30+ days from now cause noone has them in stock localy.

Let's see if @turboLScrx chimes in - he is running a Holley fuel rail and FPR.

it’s a great unit, it basically the newer version of what I have. They are made here where I live

Ok then. Ill get this FPR. Thats great cause it costs like 110 euros and the A1000 is 250...
On the fuel now. Any input on the -6AN AEM fuwl rail inlet?

Why not get the 12-880 with the -6AN inlet/outlet/return ports so you do not have to buy reducer fittings. -6AN line will support more than 700 WHP, you do not "need" -8AN line.

The holley regulator is fine. Have never had a issue with them.

I split a diaphragm inside my Holley FPR... the tech department stated that I was running too much fuel pressure for the diaphragm to last. Pressure was set to 55psi static and had 22 psi of boost... so I was seeing 77-78psi of fuel pressure. Once the diaphragm failed, a TON of fuel was flowing into the intake manifold through the vacuum line and nearly hydro-locked my engine.

Ok im leaning towards 6an now. Still everyone goes for 8an. Did anyone ever had max fow indication on 6an ? hmm

Do you remember if you have the same version or an older one do you remember?

Thanks for the input mate. What AN in/out version do you have?

‘you must have just had some bad luck, those was very reliable

JRCivic1

I agree. I convinced Holley to sell me a couple of replacement diaphragms so that I could keep it... I have not lost faith in the product at this point.

Funny thing: Back in 2002, I had the same type of failure with an AEM fuel rail mounted FPR within one hour after unboxing and installing it. I contacted AEM for a warranty replacement and was told that because I was reaching peak fuel pressures at or in excess of 100psi, they would NOT replace the diaphragm. It quickly found it's way to the garbage can.

Ok things changed cause the holley FPR at the end wasnt on stock. I got the aemorotive 13129...
For now and for the 500hp winter hp target ill run stock rail with an adapter a friend will machine...
Ill take my time and get a golden eagle 8an inlet rail later..

Thanks guys.
