I have the 380 tabs with the square rams . if i drop them down, say halfway for instance, and left for a hour or 2 i can pull the right side up about a inch , the longer i leave it the more i can pull the tab up with my hands . I am going to swap pumps to make sure it is the ram . If rams can i buy the seals and where. Thanks for any help ,

Ok i have swaped the pumps over and the problem moved over the the other side ,so now i know its the pump at fault . i am sure i have read on here that the pumps are diff from drive trim pumps?. Can anyone tell me if spares can be bought for the pump or do i have to buy whole new pump . it has the center bolt up though the middle of the reservoir.
I have done a search all i keep getting is old out af date ebey parts listed . THANKS for any help

Pics of pump?

There are checks in one side of the hoses at the fittings going into the pump. It (spring) could have failed.

I have had all the hoses off when i swaped pumps over ,didnt see any springs .
There are female brass fittings on the pump and then the SS lines just screw into them . Thanks for the help tho.

Cant do the picture thing . but they just look like reg trim pumps ,white plastic reservoir with yellow cap, one bolt up the center to hold it on. i have drive trim pumps and they look the same apart from a blanking off plug and kiekhaefer on them. Thanks for any help .

Take the fittings out of the pump. They are between the fitting & pump body.

cheers Jason i will have a look in the morning .

I took the brass fittings of and had a look ,no springs in there .took brass fittings out of the other pump , no srings in there and that trim tab stays solid ?
