hutch mod technical questions

I am in the middle of doing this mod, and am curious about the bypass suction (Im guessing thats what it is) on the side of the pickup deal? In guzzles mod, it looks like he is pushing the new 3/8 tube past that.

Isnt that there for a reason (safety for a plugged strainer?) Should you not plug it with tube?

Also, like an idiot, I pulled the suction strainer off before measuring. I think I am pretty close, but how perfect does it have to be? Just so the accordian suction thing is on the bottom of the tank right?

Cant answer the exact reason ford put it there in the first place, but it is the cause of many trucks running out of fuel, with plenty left in the tank.
If i remember mine was 15 inches long but you can put a straight edge across the tank opening and measure from there, just duplicate that measurement from the sealing surface of the pickup/sensor mount plate

I'm not sure what it is you're looking at but, It Should ALL Go! The entire concoction is a Mess and that's why your doing the mod in the first place... The strainers, mixer, short return (which feeds air bubbles back into the supply) should be removed, return extended, and simplified to finally work right.

As for the Umbrella, in order to get to the bottom of the tank, it needs to be touching the bottom without "pressing" down hard. If it's too long you'll feel it trying to spring-back when you seat the sending unit in the top of the tank. Might take some trial & error to get it right without measuring the OL first

Basically the big tube is suction, the smaller tube is the return from the bowl.

I ended up measuring from the sending unit flange mount to the bottom of the tank and took about 1/4" off that measurement (or so). The umbrella is definitely pushed uo some, but the center piece is not bottoming out. The rest of the stuff was removed and I ran a longer return line as well. (5/16 is pretty hard to bend with a cheapo tube bender)


One thing I did different than I have seen is for the filter. I used the wix filter found through a search on this site (3270 if memory serves) but cut forward of the tank along the frame rail. I used two 5/16 compression fittings to 1/8 female NPT. Then used 1/8 npt to rubber tube male (slip over pieces) and used that to mount the filter. I will get some pics when it is sunny again.

One scary thing, while doing this I noticed that the bolt for the rear leaf, front hanger was missing the nut/tab piece and that the bolt was backing out. Sure glad i caught it, now I need to find the right sized bolt. Its larger than 16mm, cause that is the biggest I have and its too small.
