Fuel pressure regulators..

[ptofnortn]

This set-up is an in tank regulator that just makes the stock regulator on the fuel pump adjustable. Cut the top off on the stock one and press the body over it. The body has a tee screw to adjust the spring pressure thus changing the fuel pressure and a jamb nut to lock it down. This kit is similar to others out there, just improved. With in line restrictors they only slow the volume of fuel down, not the pressure. Hope that answers your question.

Regulator kit

I just bought one of these kits from this guy and what a nice set up. He sent great instructions and was very easy to do. If you install this and the sled will not run on the second pull or the regulator will not adjust then you have not done it right. I have seen many different kits for this aplication and so fare this kit I believe to be the best so far. I liked it so much that I just ordered another one for my M6 also. Nice job with this product palen keep up the good work. Well worth the 169.00 and a guy that has my trust did what he said it would do and got the product when he said I would and that alone says alot. Thanx again Palen. Just my 2 cents. Im in soldotna Alaska.

What exactly does a fuel pressure regulator do? I've heard so many different explantions and want to get the right answer. Is it worth putting on my M8?

I am waiting on mine to get here.........From what I know, you really shouldn't need one unless you have done some modding to your sled. If you are stock your stock regulator will be fine, if you are modded you need consistent pressure to tune by. I am leaving the BD box and going to this regulator set at 42psi and the Attitude Industries box. Supposedly you can really nail your tuning down if you have a steady pressure and it is not fluctuating from 40-48psi. This is why guys have NO real luck swapping box numbers and it working like it should for them!

Thanks Aaron.. Exactly what i've found out myself, especialy when swaping BD box numbers as they never work the same.. I just received the gauges yesterday so I'll ship out today.. Thanks Palen

I have the time to make a few more..

Aaron, I think you are right on here. But I don't believe the stock fuel pressure moves around. It just as a large window for the spec from Arctic Cat. So it could show up running at a 42 and the next guys sled could be running at a 48. The spring in the stock regulator has a range. They can only get so close with a fixed regulator. But with an adjustable regulator you can nail the pressure by making slight adjustments to the stock spring tension.

I agree 100% that when tuning with a box and exchanging base program numbers the fuel pressure is a key part. No reason to talk to a guy running 48psi if you are at 42. Your numbers will be way off.

If you both are at 42 then you have some options.

One other thing I would suggest.

When setting up your new adjustable regulator. Set the pressure high enough that most of your box numbers are "0" zero's. Then tune the lean spots with the box or even cut a little fuel in a couple spots if needed. The reason for this is if your box craps out on you in the bush you can by pass your box, have enough fuel to limp home. If you run mods and set it at 42 psi then add 10 points of fuel accross the line then your box dies you will be in the tank adding fuel to get home.

Just a thought.

Thunder and a great idea.

Very true. Good point. The reason I was probably told to run 42psi by Derrick at Attitude is because I am using a Generation 3 box and it only pulls all the way across the map. I think the newer boxes you can pull in each area. Maybe I will set to like 45psi and lean his settings a bit. Thanks for the post!

Making parts for more kits.

 

[AaronBND]

Just installed this kit this afternoon. Very nice setup! It took about an hour. Directions were great and the start settings he gave landed me at 40psi for a starting point to adjust from. Tank was half full and not a problem. Going to be really nice being able to tune to a consistant pressure. Thanks Palen.........................
