Hutch mod testimonials? Harpoon mod?

[ScottyP5947]

Hey all -
I am just learning about the 'harpoon' mod where you chop off the filler tubes in the fuel tank to avoid all the foam. I am almost willing to drop the tank just for this benefit alone, but I am guessing that I should do the 'hutch' mod to prevent air in the fuel line while I have it down, right? Thing is, I am just not sold that it's something I will benefit from. I could care less about the sound, cackle is not going to make me worry. Will I REALLY get better power and MPG or is this just BS? Can I get some testimonials, or anyone think it's not worth it?
Seems that the harpoon mod has TONS of fans. Does it work well? For my TDI VW, they have a similar mod where you remove the fuel tank vent and it works GREAT to prevent the foam. Fill right to the brim every time, in no time.
Is it a pain to drop the tank and do the hutch/harpoon?

Thanks!
Scott

easy to drop the tank , just do it when your almost empty.

i did both the hutch and harpoon mod not too long ago and im glad i did. I noticed a much quieter running engine and i can go 100-125 miles before the fuel gauge even moves off the full mark.

Any diff in MPG or power on the hutch?

you not gonna notice any power difference and maybe a slight bit in milaage but just the quieter engine and actually a full tank of diesel is worth it to me. When i did mine i also added a pre-pump filter like in the kit ITP diesel sells. I would just order a kit from there or if you dont want the filter get the kit from diesel innovations.

how does it make the engine quieter

[ScottyP5947]

From what I understand from reading up on the mod, it prevents air from getting into the fuel line by replacing some of the pickup hardware. This make the truck run ssmoother and thus quiter? Are there any before-after videos of the sound difference? Lots of guys seem to want to make the truck louder, deleting insulation, etc so that's what is strange to me. Anyone else feel this is an 'important' mod? The noise reduction is really only at idle too, right? I just filled up so I'm not going to do it this weekend. Not sure how many gallons the tank holds, but I just pumped 34.5 gallons.

well worth it, just drain the tank first... both hutch and harpoon

What did you get out of the hutch?

The reason for the mod is to keep the air out of the fuel lines and thus out of the injectors. It does make it quieter, but not all that much (at least not when I did mine) It is a little bit of cheap insurance for your injectors though. Air isn't good for your injectors and can cause premature wear. I doubt you would see much, if any gain, but the piece of mind on extending the life of my injectors was well worth it to me.
