I have been looking on the forum to see if there is a after market drop in fuel pump for a Studebaker tank. I was thinking that it could drop in where the fuel gauge float is located and you could have combined fuel gauge/electric fuel pump operation. Any one know of an application? If not, are there tech experts that would have an idea to modify an existing application?

I looked into that a few years ago and the hole is too small for the in-tank fuel modules. So, I went with a external pump.

There are places that will modify your tank to install a sump and flange for the lock ring so a pump/float assy can be installed.

The situation may have changed though....


Here are some links after a quick search. No experience with any of these:

Some of the above look like could be they fit in the sender hole. The ones I remember from years ago, the tank was cut and a recessed section welded in for the pump mounting flange.

I have been running in-tank pumps, in conjunction with EFI, on the 62 and 63 GTs, for several years now. I got them from tanks inc.. It takes a bit of ingenuity to fit them into the Stude tank, but not that difficult. OTOH, if I ever installed another EFI, I'd just go with an in-line pump. They are pretty much trouble free nowadays, so I have heard, from a reliable source.

An external in line pump is the way to go. Simple to install and replace if the need arises. I hate draining and pulling a tank to get to the fuel pump, don't you? Mine is very dependable having installed it two years ago. I use mine with a toggle switch to fill my float bowl as my car sits for over a week. Modern fuels evaporate very quickly especially here in the desert. I only run the pump for a few seconds, shut it off and start the V8. Works like a Champ on my Lark. (Pardon the pun)

If the OP was talking about a pump for a carbed motor, I would not even consider an in tank pump. For same reasons as you. But when I ran electric pumps in carbed Studes, I always did away with the OEM mechanical pump, and just used the electrical.
