WOW Dave !!!!

You actually found those? I had ran into the same problem and looked high and low. Even Patricks did not know where to get them. I looked at the output of the pump and it is 3/8 and when it goes into the block it is 3/8's. So what I ended up doing is getting some 3/8's steel line and new brass and bent it like the original.
I even went to the junk yard to find one.
The 53->54 and the 55->62 235 tubes are different.

When looking at this, it will only flow with smallest diameter which is 3/8's I don't know why the put the larger tube from the pump to block.

Do you?

Thanks,

Brent
