I have an application where the tank is so shallow I'm not certain that the pump can stand vertical and still mate with a line coming down from the sending unit top. I was wondering if there is a fundamental reason which would prevent a pump like a Walbro GSS342 or Deatschwerks DW200 from functioning properly if mounted to a bracket on an angle of up to 45 degrees. I was planning on using the Holley Hydromat to avoid having an issue with the pick-up position.

Thank you,
Scott

I don't see why the pump wouldn't work even if it was mounted horizontally as long had fuel to it. I would suggest that you mount it as vertical as you can and then make some type of connection to the Holley Hydromat so it lays flat. I believe the guts of a Walbro pumps are basically the same, the difference being the in tank models are sealed for that use. Larry

Thanks Larry. That's what I hoped others would say.

A little more detail regarding what I'm trying to do. I was thinking of adding a line to the factory sending unit as the pick-up and using the factory pick-up as the return (it goes to the tnk bottom and the float is mounted to it). Things are so tight above the sending unit they basically welded/brazed the stock 3/8" tube in the area of the bend to minimize the height above the sending unit. If I can duplicate that on the line I plan to add then there might be enough room to keep the pump vertical but there is little room to work. Making matters worse the Walbro pump is 5/16" out and I want the pick-up to be 3/8". Working with a mismatch is never easy. I was thinking of trying to roll the 3/8" down slightly so I could get the 5/16" submersible fuel line over it and the pump outlet with clamps on both parts. There just isn't a lot of room.
