Since we are a full fuel shop and not just a guy selling parts you can get ahold of us and ask us questions if you have any. We also offer anything else you may need to do the job, just let us know what you need and we most likely have it in stock since we rebuild these pumps daily. If however you buy all the stuff and end up still having issues you can send us the pump and we'll be happy to rebuild it and recalibrate it with our Bosch test stands. If you did need us for this we would credit you back for any hard parts that would have normally been replaced minus any costs like shipping and ebay fees.
Most of these pumps run $600-650 to rebuild with the new upgraded weight cage, so you could deduct any parts you bought from that.
You can contact us at Badger Diesel M-F 8am-5pm
