was thinking of this one for my stroker

I have heard one mention of them on here, but curious if anyone else uses their stuff...supposedly all made in the USA

http://fuelab.com/ i recommend fuelab imho. i have never used the sx stuff but fuelab is about as good as it gets in the fuel pump industry, tell them you heard about them on yellow bullet and that David Hearn sent you. thanks and good luck

well I went to their site and it lists them all as efi pumps...sounds similar to using a walbro pump, and those walbro's have not fared well in low fuel pressure applications i.e. carb from what i remember...are you currently using one of these?

With few exceptions, no pump should be allowed to dead head.

I sold Fuel Lab for about 2 years and had the first 4 I sold come back, and several more over the 2 years. I wouldn't sell or use one again if you gave it to me.

SX makes a good piece.

I've had 3 SX pumps. I just sold one that was 10+ years old and still working great. The other two I still own and no problems. Ever. All were purchased new direct from Essex. Very easy to deal with.

I had a SX when I had a 383 with a wet direct port nitrous system and the SX worked just fine with no issues other than that damn cavatation problem. I guess it worked to good.

I ran their large efi pump for 3 years and then another 3 years on my blow thru e85 system. Best quality pumps I have ever seen. SX pumps are the only pumps that I have heard of or found that the US military uses on their vehicles and in their fighter jets. As long as you follow the line size and pump mounting directions, cavitation should not be an issue.

SX are great pumps

this is good info guys! thanks! I think I will stick with SX stuff. Looking to run a mild motor on a bit of spray, one of these should be enough I would think if guys can do it with holley blues

They work great, but I wouldn't trust them over 750hp. I ran one of them years ago on my sbf with a plate unit. We put a blower setup on my buddy's car (360", vic jr heads, J trim Mondo) we ran two of them and ran bottom 9's with it, never had any fuel issues.

I originally saw you say you had used them in an older post, which i then decided to check them out

do you think the pump I listed in my original post at the top would be enough for a 400hp motor with a small 150 hit at most?

Not sure, but definitely don't dead head.

I ran a single SX on my car with the fuel injected 302, twisted wedge heads, x-303 cam, GT40 intake. It ran 11.80's n/a and 10.60's on nitrous and I ran one pump.

Used the same pump on my other car with a carb and a 302 with victor jr heads and a 150 shot and that ran 10.20's

-10 feed line, -8 return line with a Mallory 4309 return style regulator.
this is the one I used -

Personally, if you were going to run that pump, I would get a holley blue or some sort of other fuel pump to run only the nitrous.

you can try it, just keep an eye on your fuel pressure regulator and see how much the pressure drops when you hit it. Not sure if that pump can recover quick enough to not risk hurting something.

well i guess to be on the safe side ill step up to one of their other pumps. Not sure which one is a step above. Ill give them a call and see what they recommend. Havent found many dealers for them though
