After a lot of grief with the K-jet system on Susan's 245 I am seriously
considering putting a carb on it. (I understand them better than K-jet.)
(Yes, I DID get the D-jet system on the Yellow Peril working OK.)

Anyway I am wondering, since the in-tank pump seems to put up about 5 psi,
how it would work with, say, an HIF6 carb. Would I need a pressure regulator?
I already have a single carb manifold, most kindly furnished by Bram Smits.

Any comments on this would be most welcome.

Doesn't the block (B21?) have a place inline with the distributor and driven by the idler for a mechanical fuel pump? Those things are reliable and last for years.

It does have a place but it looks like maybe it is a different pump than
used by the earlier models. I will check it out. But the in-tank pump is
already there and if I just bypass the high-pressure pump, it might be
quicker, cheaper and easier.

Waht I wonder about is the difference in application as a continuous running centrifugal pump intended to continuously move some volume with a return system. I can't think it really needs that volume for cooling like the positive displacement unit it was configured to source, but wonder about its performance pushing drops at 5 psi when the tank is low and its in free air. What could you lose trying?

George! Fancy seeing you over here on the 200 side of the world.

My guess is that it won't likely work, but I could be wrong. I don't know that the prepump is up to the task of pushing gas and keeping pressure up for that distance. I'd think it just sorta sucks enough gas when the tank is low to gravity feed the main pump. I could be wrong though. You could always get a universal inline pump for cheap if it didn't work though.


My question though... geez. I'd really be trying to sort out the problem with the injection, as it's so nice when it works right in every respect... cold starts, mileage, emissions... I might be getting another 240 myself soon, and if I do, it will come with a wasted spare engine with complete K-jet injection attached. If I get that, you can have what you want, as the car seems to be OK.
