Re: Secondary fuel pump dead?
 

Subfixer, did you need to do any modifications to get these pumps to fit into the sending unit? I received the kit from Lingenfetler and all ways going smoothly until trying to slide the new pumps into the frame.

My stock pumps measure ~36.75mm in width.

The Walbro GSS340 pumps I received from Lingenfelter in the high flow kit measure ~39.18mm in width and will NOT push into the holder.

I don't see how these are going to go in without cutting a slit in the side of the frame for each pump, then praying to the zip-tie gods it holds together.

Yes. I split the holder down one side. Secured with tie wraps.
