Do you have a picture of your setup? I have a couple caps to turn the stock FPR into an adjustable but it only works on certain setups. Im not familiar with the iron head 60V6 fuel setups. Going by that picture I think mine will work but I don't know if that one you posted is the right dimensions in that style.

Thanks for your answer , these are pics of my engine , this is what your you need?

Ok, there isn't much room under there to add an adjustable regulator cap, nor to adjust it with the engine running. Im not sure if the cap you posted will work or not given the space to work with.

The space I do not believe that it is a problem , enters a finger between the collector and the regulator , and the adjust I can do it with the stopped engine before placing the collector , what do you think?

Thank you very very much.

If you can pull the plenum off and get a measurement for height, then the clearance with the adjustable one can be found out. If there is room for it to fit then you could adjust it by pulling the plenum every time but thats time consuming.

Just curious, but why do you want an AFPR?

i had a holley adjustable regulator on my motor. it was for a 305 tpi, but the same regulator as the ironhead 660. it was nice because it had a dial on it for adjusting instead of the screw, so adjusting with the motor running was no problem, and it fit under my plenum.

I am going to watch the holley , Thanks.

" but why do you want an AFPR? "
because I have put to the car , headers ,cleared the catalyst and egr , procomp unit , sparks denso iridiun , now i am going to buy a new sport camshaft and I think that I needed more fuel.(measuring CO2 it leaves very low)

Its more likely that your computer needs tuning if its reading lean. Those mods don't look like enough to max out the injectors.

sorry , too i have a jetperformance chip and a new accel fuel inyectors , with the chip I am not very happy , but only have two in summit and I believe that buy the worse one , this was before knowing this web.
living in spain and my problem with the language , is a problem to look for the pieces always well.
by this I thank for much yours advice.

[SappySE107]

You don't want to run one of those performance chips. They are garbage for these motors unfortunately. The companies never put any real effort to actually tune so its generic changes that don't do any good. Im not sure what software is out there to actually change the tables in the computer.

[dogarfe]

by that reason I want to increase the pressure of fuel, because not like changing the times of ignition or inyection , in 60degreev6 Store sell something recommendable for this subject?

[SappySE107]

I don't have anything that will fit under your plenum, or at least it certainly doesn't look like it. The cap I have go on the newer engines with the regulator sitting on the end of the rail.

some of those Chips i can to put in my car?

That regulator may be a problem unless you can verify that you have equal to or greater clearance than it provides on the TPI V8 engine which is what I used it on and it was a little close there. Another option and what I did on my fiero 2.8 as opposed to changing fuel injectors was shim the original regulator to the pressure desired, pennies, nickels and dimes work well. Remove the cover from the regulator with the proper hex bit, place a nickel on top of the regulator, press the cap back on and put enough screws in to hold it and then evenly tighten them down and check your pressure. This method has worked many times and I never had a problem with a leak.

Usually the fuel pressure increase is recommended by the cam manufacturer when no ecm mods are being made, a long time ago Summit offered a cam with a chip for the TPI engine.
