Revs keep dropping

(1/3) > >>

TicTac:
hi guys
thought i sorted this problem but obviously not...... disco started loosing power and the revs really droppped off. i had really run the tank low so i assumed i had sucked up crap out the bottom of the fuel tank. changed the fuel filter, bled the system and it seemed to do the trick then today it started loosing revs again and struggling to start.
then it will run fine........... any ideas wot the problem cud b (other than the fact its got a green badge on it)!!!!!

Disco Matt:
Could be the fuel lift pump, but if you were able to prime it with the manual lever on this then it probably isn't. I'd check the metal pipes coming out of the fuel tank, apparently they can corrode.

TicTac:
couldnt prime it using the lever, it turns but nothing happens so just kept cranking the engine. it worked eventually!!! got a flat battery in the process..... so cud it be the fuel lift pump?????

Disco Matt:
Yes, it might well be, certainly I would change that first as it's not too pricey. Mine failed after I changed the filter and tried to prime it, pumping the lever did nothing and I had more or less exactly the same symptoms.

biggerlandy:
have tou checked sedimnter  on inside of nsr arch if you have one i have a few probs with them lately just remove it and new pipes inplace :)
