Small fuel pumps for TBI?

Post by dac »

I'm attempting a low performance project - a TBI system for a 1939 Ford 9N tractor - to get started. It is a 25HP engine that runs at low RPM. I don't think I need high volume in this application, and lower power consumption would be good. Since everything seems to be sold by original application rather than specifications, I'm looking for suggestions for a small fuel pump that might be a good match.

I read about a Delphi T-11 but don't know of a source. Probably something from an very small car would be Ok. Something cheap or likely available from a salvage yard would be good. An external pump would be easier to work with since the tank isn't set up for an internal, but any ideas are welcome.

Thanks for any ideas or links to similar projects.

I don't know any specifics, but have you looked at motorcycles as a source?

I have used a few late 80's early 90's f150 external pumps with success, they are cheap and easy to find.
They are not that large an should be able to be hidden under the tank.
Have you converted to 12v? How are you planning to run the return line?
You could try a single injector tbi from a 93 gmc sonoma 2.5L. That tbi style
has many different injectors avail for different flow rates.

If you've converted it to 12v, you might consider the Ford fuel pump referred to in many places in the forums. It's around $100 and should flow more than enough fuel for you. With a regulator and a return line, the increased availability of fuel will not be an issue for you.
