I was able to pull off this conversion on Sunday. Car runs well. Super easy install.
today i upgraded fuel pump to an intank Walbro 255LPH and tested with 100% e E85.. Its really strong now.. it would be really interesting to measure the WHP now... im a bit blind when it comes to hp... but the car really give you a ride i can tell you that.
Below are detailed instructions for the 4 steps needed for E85 conversion: installing a Walbro 255lph inline fuel pump
have the 1.8t 630cc Genises inject, walbro inline, and a 50 trim turbo.
i have been running a walbro inline fed by my stock intank pump with a 130000 miles on it. i had no problem making 530+ hp with this pump.
-Front Cross member (motor mount half): passat vr -Front Cross member (radiator half): mk2 modified - cut around 1/2 off of mid section on pass side -K-Frame: mk3 vr6 -A-Arms: mk3 vr6 -Struts/Springs: mk2 lowering springs
I sold an Airtex fuel pump for a Mk2 GTI that had the factory part number filed off (like the part in the OP), and it had been painted, and you could see where Bosch was printed on it under the paint.
oh its some fun getting the screw cap back on the tank. the problem is a stock pump the line sits horizontal and with the walbro it sits vertical. it requires some force and patience to get it in.
I went through 4 Airtex pumps in about 1.5 years in my car. I seriously thought there was a problem with my tank or fuel but it was clean as a whistle in there. Finally upgraded to a Walbro and haven't had an issue since.
Fuel-pump... intank Walbro 255lph gave it all up today as well.. i knew this was gonna happen so i alway drive with one extra stock pump just in case.. been there b4.. I can now feel a bit diffret performance with th stock pump and this setup... Car runs more rough in the engine.. and jerks sometime.. i don't even think the stock pump is good to handle 100% 95 octane fuel.. i recommend over and over dimensioned when touching 300hp... on 95 octane... The inline walbro solution should be good.. as mentioned b4 in this forum.. I have an Bosch 044 in the garage that im gonna try in tank. Think the intank walbro runns fine with E85 if you run 150hp.. but with 300hp.. it have to work the as off to deliver E85.. with poor lubrication
