in tank fuel pump pressure?

does anyone know what the in-tank pump puts out as far as pressure? I'm working on using an intank fuel pump from a 1982 volvo 240 in a modified Yamaha Virago xv700 motorcycle and I need to make sure that it can put out the needed pressure. Does anyone know what that pump is spec'd at?

Thanks much

Don't know if there is a spec, but I would expect it to be somewhere around

1 psi. It is an impeller pump, a lot like an aquarium pump.

Your right, just dug out my manual, 2-3psi. shoot...

I heard that some volvos have in-tank pumps only for their fuel system, which ones are they? (might as well start shopping around for the right pump now in the planning stage.:) )

I think that is the ones with Rex/Regina fuel/ignition setup.

The 740 with non-Bosch (Regina) have only one pump in the tank. Also all the new ones, 850, 960 95-(inline 6), and newer have only one pump, and it's in the tank. All these pumps will work at what I think would be too high a pressure for any carb, you'd need some kind of pressure regulator with a return line.

Since I'm using the pump to provide fuel to a pair of injectors (with a fuel pressure regulator at the end) there shouldn't be a problem with to much pressure. More of a problem with not enough in my first choice (2-3psi just woln't cut it.).

What I am doing is replacing the carbs on my motorcycle with fuel injectors. The carbs are in very bad shape and are no longer supported (impossable to find some parts without going to a salvage yard). Right now the bike will run on them but it's a very messy run, missing and backfireing allong the way. The real problem is that it idles at 4000 rpm, which for any manual transmition vehicle can be a bit of a chalange from a standing stop, or for going down a steep hill (in SW Wisconsin there are hills a-plenty!). So I have purchase injectors from a 600cc arctic cat snowmobile that should be the right size for my bike. At first I thought I would use the in-tank fuel pump from my '82 240 (junked cuz of cracked head + major body rust) but now I find that it woln't work, so I guess I'll look around for one of those cars you mention (either in junk yard or maybe online, use parts? new aftermarket? whatever is cheepest) and get me a fuel pump. I want it in-tank cuz there is little enough room on the motorcycle for the ECU (product called MegaSquirt) and hiding the fuel pump in the gas tank is a very elegent solution. :)

Thanks for all the help you guys have given! Erik of Ekedahl

P.S. Just so you don't flame me for being totaly OT for this group, I am a volvo driver! I have 2 currently, '88 240 and '64 p1800 EE

There are lots of cars that only have tank mounted pumps. I think most GM products only use one pump. I helped change a tank sender on a GM pickup a couple of weeks ago that was so equipped. There are thousands of those things everywhere, and pumps may be available very cheap.

Thanks for the tip. Chevy in-tank fuel pump $63, Volvo intank (when it's the only pump) $130. I'll go for the chevy pump. :) Thanks!
