ped Posted August 6, 2023 Share Posted August 6, 2023 whilst checking for leaks on the 300tdi i'm fitting to my work 110 i've discovered the vac pump has a dribble running down from it and over 3 days a 50p stain on the floor(i was hoping to not have any oil leaks for at least a few months) now everywhere says they're a carp design and i've seen posts on fitting a electric vac pump from a volvo or jag which seems staight forward if wired into the brake lights but is it better to fit a vac switch and if so does anyone have a link to one that will work in the right range (on at 19 off at 22 from what i have read) Quote Link to comment Share on other sites More sharing options...
muddy Posted August 7, 2023 Share Posted August 7, 2023 I drilled the rivets out on mine as they had come loose and were not clamping the o ring, replaced with A2 button heads and nylocs. 1 Quote Link to comment Share on other sites More sharing options...
western Posted August 7, 2023 Share Posted August 7, 2023 Pretty sure mmgemini did a similar fix on his 300tdi vac pump. 1 Quote Link to comment Share on other sites More sharing options...
fmmv Posted August 7, 2023 Share Posted August 7, 2023 I have seen these used in some kits, switching the pump via relay. 1 Quote Link to comment Share on other sites More sharing options...
fmmv Posted August 8, 2023 Share Posted August 8, 2023 I have looked at doing this - I think it might be wise to use a reservoir of some kind and 2 switches, one to control the pump, and one set for less vacuum to switch a warning light, then if the pump fails you have some warning of loss of assistance. 1 Quote Link to comment Share on other sites More sharing options...
ped Posted August 9, 2023 Author Share Posted August 9, 2023 i was talking with my old man and we have a pump and switch in the work shop as he's fitting it to his tvr as like the drag cars his set up has very little manifold vacuum i don't think a seperate reservoir tank would be needed as from more reading many just splice into the brake switch output,this i'm not sure i'd do rather having the inline vacuum switch at the end of the day it's not race car thogh but a slow plodding work horse Quote Link to comment Share on other sites More sharing options...
