Fuel Filters? Loss of power...supercharger

[johndjmix1]

They changed the fuel system in the later H2's. I remember when installing the SC the parts were different from newer to the older. Im sure im on the newer fuel system.

Yea, i was figuring the sock was just to stop large debris....cant imagine that would be the only filter.

Im not running real lean, im figuring this since the thing doesnt ping....and I run 85 or 87 octane (Always have).

The real question here is, would I notice a power loss if i had a clugged injector or would I notice lean behavior such as pinging...? Im sure someone on here thats ran lean can let me know the answer.

Thats wierd cause i just replaced mine not too long ago. Heres a picture you can only see one of the lines cause both lines run right behind one another. This is the part number i got: AHG9344

Do you have any guages? Wideband, fuel pressure, boost? Could be alot of things but I would guess that if you have good pressure then thats not a fuel problem. Better gas will usually equal more timing/power. Any belt dust? Maybe slipping belt, spinning crank, vacuum leak, etc. Have you thrown any codes?

Alot of the fuel filters are located above the crossmember under the center of the truck. Mine is atleast.

Try going to premium fuel (which is recommended with the SC) and use an injector cleaner like Techron. I had the same problem and it turned out to be bad fuel. Now I only run Chevron or Mobil premium.

Yea, true....maybe because of the 85/87 ive been running its been backing way off on the timing causing a power loss., since when i first installed the SC i ran 91 and it ran good enough to kill a transmission in a few weeks.

Next tank ill run preminum and see what happens.

Running a supercharger on 87 octane in my opinion is just crazy, even conservatively tuned its still a bad idea. You have all that money invested why not spend another few bucks per tank and have the piece of mind.

you don't run cheap gas in a supercharged or turbo charged vehicle ,step up to 91 or 92 octane. throw a can of Seafoam in the gas tank and it will clean the injestors and remove carbon deposits,nothing I have ever used works as well as Seafoam .you might consider a Walbro fuel pump ,it will deliver all the fuel you need .
