1976 DT400c
500-13101-01-00 is the pump part number according to schematic
Discontinued...
I busted the ears off my housing (don't ask) 
Anyone have one that is for sale no longer using that maybe is a pre-mixer now and doesn't need?
This pump worked fine but the ears that hold it to the case are done
(so the pump casing is trash)
I hear Deet rebuilds them, maybe you have one for sale so I can get this DT to Daytona again next month?
Thanks for any direction
Cheers
 

Take a look on UK E-Bay.

Much thanks Andy C
Found one in the US reasonable just now and ordered gasket / screws / case gaskets as well
Shame too, as mine was spotless... until I broke it!

Daytona bike week here we come
 

Good to hear you are sorted.
Howe many miles do you have to ride the DT to get to Daytona?
Bought my DT last year for road use only in the summer months, just wondering how good they are as a road bike - pretty happy with mine so far.

Daytona is about 200 miles each way from my house. 
i just trailer it up (with many 2 stroke friends)
we set up command post in the camping area in the speedway infield. We ride around the infield to various parts of the track… then after the races head into town.
15 two stroke vintage bikes in a sea of Harley’s. 
sounds like a swarm of wasps coming at you!
bucket list for sure!!!
mines been reliable but steer clear of highways and over 60mph continuous myself. These are almost 50 years old
I use mine as a cruiser. With the occasional “get on it”

Sounds like great fun.

I shall be using my DT400 for weekend rides in the summer - probably about 40 - 60 mile rides, as well as going to the odd bike meet / vintage motorcycle run.

I have a fully rebuilt pump off a 1974 DT360 that partzilla says is the same part number. Might be willing to sell if price is fair, PM me if interested with fair offer.

ignore me, its early and I missed the bit that you had found one, glad you did and hope it works out well!
