fuel pump question

[Cdc1221]

Ok so i just bought a 91 tsi awd, and it came with a high flow fp with part # hffs-510, and i tried to trace it by number to see what pump it was to no avail. Any ideas as to what it is? It just says highflowfuel.com and their phone and fax on the pump

Call them and have the part number in hand. Sometimes companies wont advertise stuff by PN, they will do size and if you don't know it, you wont find it.

i cheked the site and they dont have that part number... but all they have for 1g dsm is 255s
