fuel filter switch

[blzrgb]

Bought a new fuel filter block from a guy on ebaymotors for my 1008 and when it got here it didn't have the fuel pressure sensor. I happen to have a few new ones so no big deal. Or so I thought. The new filter block I bought has a smaller diameter place to mount the sensor and therefor my switches won't fit the new block.Has anyone else had this problem?

Yes i had the same issue i bought one also i hooked everything else up and left the sensor wire off the wiring harness unplugged and i have has ZERO problems not having that sensor on my fuel filter housing.

How did you keep the filter block from leaking fuel without the sensor in place ?

thw newer blocks dont have the hole machined in the sensor area for fuel to leak out.

That's what I thought. But the "new" block I bought has the machined hole in it and the pressure switch just won't fit. That's what's got me bumfuzzled. It's like we're dealing with 3 different types of blocks OR 2 different types of pressure sensors. Does that make sense ??

thats odd !!! i know a guy on here had a block and a small freeze plug fit in it and he did not have to use a tap he just pressed it in to the housing.

GM did away with this switch later in life. It is not something that was for military only and they took it out of the prints. The newer fuel filter block is not drilled for the switch so there is no problem with using it and fuel leaks.
Plug it in and go!

The new block I bought is drilled for the switch and the sensor won't fit. That's what has me puzzled here. If the switch won't fit, it must be the newer block, but fuel will definately leak because it's drilled out and fuel will pour out the smaller brass elbow.

Ok, my question is what does the switch do? I have been looking on the site for the answer but have had no luck.....
