Is there any O.E. applications for an external fuel pumps that have a working range of 35-45 psi?

I'm helping out a friend that is transplanting a Yamaha R1 powertrain into a Banshee four-wheeler and thought I would give the experts a shot at this graemlins/thumbsup.gif

You can buy the pump that Holley sells for it's projection. Look for the Holley 12-920.

Make sure he uses a return-style regulator.

Yes, that's a Walbro 255lph pump, works great for me. :D

Look at the older Fords. They almost all had external pumps at one time on their 5l engines. They have funny connectors but you can get pieces of hose with the connector on the end or get them with a used pump. You can likely get a pump from a wrecking yard for $10.

I use an Accel external electric pump (ACC-74701) that maintains 45psi for my Accel SuperRam injection. Summit has 'em for $146.

Peter Peter,
That's what I'm looking for. My brother was a ford service technician and is now a service writer. His suggestion was for an Econoline Van. I just wonder what operating range these pumps work at with their throttle body injection.

Two independent suggestions for the same thing…must be on to something here. Although I think my friend is crazy for putting a 154 horse motor into a four wheeler, but it should be fun!

Did Fords even have throttle body engines at any time? I don't pay much attention but anything I have looked at was multiport. The pump I'm referring to would come off a Ranger or full-size truck or Mustang or the like. Look for a late 80's truck with external pump and a 5.0 engine. They were for multiport injection and I've seen a Ranger one make 100psi when the regulator stuck closed.

They have funny connectors but you can get pieces of hose for them. The Fords had all plastic fuel lines with these pumps. Or, I used one and just screwed a different adapter into the end. The threads were slightly different (metric vs imperial) but I just forced it in. What's it matter with a $10 junkyard piece? On the inlet, I just flared the end of it a bit with a brake line flaring tool and then put a hose over the connector and clamped it down. You have to see one to know what I mean.

Hi Joe,
I don't know if you remember this R1 project?

My buddy got it street legal now believe it or not.... :eek: All we used was the R1's stock electric pump. You can see it in picture 027_24a (at the end!), follow the fuel line from the blue filter towards the engine. Seems to work great. The fuel tank is mounted behind and above the engine and fuel pump. We did have to richen the carbs a LOT to make it work right though. Might also be because of the ram air intake. We had to pressurize the carb vents to the same pressure as the inlet, so that might be part of why it needed so much jet.

Good luck with the R1 project.....You'll have a blast!!

chris Chris,
I remember it. Cool project.

This banshee is being upgraded from the FZR 600cc 100 horse powerplant we swapped in two years ago.

Thanks for the help guys. I wouldn't doubt it if the "next" project is to swap on a turbocharger. :eek:
