Thread: In-Tank Fuel Pump

  1. #1

    Default In-Tank Fuel Pump

    Hello, this is my first post here. I'm the new owner of the Holley Sniper and have not installed it yet. My vehicle is an '89 S10 P/U with a Gen 1 SBC that puts out just over 400 HP. It's .060" overbore, has forged internals, aluminum heads, long tube Hedman headers, using a large cap HEI distributor. I'm looking for some direction as to which in-tank fuel pump is tried & true with the Sniper? I have a Holley bypass regulator on my carbed setup now. Do I need a different regulator? Thanks.

    The Walbro fuel pump is the most reliable electric fuel pump I've ever used. Contact Chris Myer at or He's a Holley EFI parts professional/fuel pump specialist.

    Thanks. I think I found one through researching that should be OK. It's a Walbro GSS341. Now I need to find a regulator.

    The regulator you currently have for your carb WILL NOT work for EFI. If you bought a Sniper EFI it already has a built in regulator. No need to buy another one. You will need to run a fuel return line if you don't already have one. The Walbro 255 pump will work fine with your engine. I noticed you posted a link to just the pump. You will need a bracket to hold it, a sock filter, anti-slosh tray and other items. Tanks Inc sells very nice complete kits. They come with good instructions as well. Look at the PA-4 or PA-4P kits:

    An '89 S10 should already have a TBI tank/sender. No need for aftermarket tank in that case. It’s already setup for an in-tank pump.

    I’m sorry, my mistake. I didn’t notice the year, I always work on old cars that had carbs. I wasn’t thinking about something newer that came with EFI. Danford1

    Thanks for the replies guys. Yes, I do have a "new" in-tank pump currently for the carbed setup, so I'll just mount the new pump to that. I also wondered why I would need a regulator if the Sniper had one built-in. Seems like a lot of people have them anyway, so I wasn't 100% sure if I needed one or not.
