Aftermarket fuel pump for seca turbo?

My turbo has been running perfect the last 2 months till tonight, when my bike started bogging down, sounding starved.....I knew exactly what it was, shut the bike off and coasted to a stop. I put it it gear, hit the start button, and didn't hear the familiar whirr of the pump. When I got home and slightly disassembled the bike, I tapped lightly on the pump housing and it coughed back to life....for about 3 minutes. ...then died again

I've already taken this thing apart once to free it up(picture at bottom), and it was a major PITA since the housing is crimped shut at the factory. I just don't trust the reliability of this pump anymore. Do any of you TURBO guys run an aftermarket fuel pump? I know it has to be constant running pump at roughly 18-20 PSI for the carbs to get adequate fuel. Does anyone own a car maybe with a fuel pump around 20 PSI? I'm hoping there's a pump out there somewhere that's similar.....It sucks when you realize your main bike is suddenly grounded :cry:

These run the same pump as the EFI a suitable replacement is the Airtex EP6910 EFI pump.

Edit ok I can't find info on this pump on the web so I have emailed Airtex support to see if they can provide more details, also asked Dave what the pump came out of, will post here when I get an answer.

 

Got a reply from Dave:

I went through this a couple of years ago and we couldn't match that pump anymore, it was about 12 years ago I got that one. It just a normal aftermarket pump I got from autoparts (new) It was for a small FI engine and ran to 90psi max and has a right angle connector on the outlet end (I think).
End

Try taking the pump to a auto part shop and match it up to one in their catalogues might be your best bet. Will let you know if Airtex get back they may have something similar.

 

I've often wondered about this myself. Any pump that does more then 20psi will do as the Fuel Pressure Regulator will take care of the rest, but the key is the Gallons per Minute or Gallons per Hour rating.

I dont know what the volumetric rating is of our pump, but it would need to be replaced with something that does similar volume and is capable of more then 20 psi, and then the FPR can take care of the pressure.

Thanks for your help Kiwi, I'm hoping to find a suitable replacement that doesn't cost over $100 usd.........BV-1, maybe 90 psi might be a bit much for the regulator? I don't know, but i'm thinking 40 psi should do the trick.....i found this pump browsing google

http://www.spiderautomotive.com/fuelpump.html

 

Standard pump specks:

98.1 kPa (1.0 kg/cm3 or 14.2 psi) relief valve at 2.5 kg/cm3

40 psi would be fine, it will be hard to find one less, the regulator will handle the pressure, pump should only work as hard as it needs to to keep up with the regulator.

Speck calls for 300 ml of fuel pumped in 15 seconds.

 

Excellent info Kiwi, are there alot of 750D's out there? I know the factory pump through Yamaha is on backorder......with a msrp of almost $900 8O that's more than I paid for the bike! I ended up getting my old pump functioning again, but who knows for how long. If I go aftermarket, I'll let ya'll know how it goes. Thanks for the input!

hi,i have a fuel pump from an 82 vw rabbit in my 82 turbo seca.you will need the banjo flange and nut from the vw pump for the fuel line.
the pump has been in my bike for 3 years and works great.it is a bit bigger than the stock seca pump so you must remove the stock pump mount and build your own(foam and zip ties in mine).

 

Hi don't know anything about the turbo bikes and fuel pumps.. but I did own a 1100 magna and they had fuel pumps.. not sure what kind of pressure they put out,. might be an idea checking it out .. just a thought..

xj turbo, did you also clean up the screen at the end of the pump. Its one of the two filters that were on the turbo. One of them being the tank strainer and the other was in the fuel pump. Also once the pumps are working they should continue to work as long as they don't get gummed up. I have probably 60,000 miles on mine, most likely more than that in the last four years that I have owned this beast, err beauty. The fuel pump is rather simple and since you have had one apart already, try to find another and do the same. This way you will have a factory back up if yours happens to act up again.
