Blocked fuel tank pick up pipe
« on: April 13, 2019, 01:22:29 PM »
I have a late model moke fuel tank out of the car and the pick up pipe is seriously blocked. Have tried compressed air, wire doesn't work as too many S bends. Anyone got any ideas, i thought a liquid of some sort like brake fluid as that seems to do the job on paint etc. This moke has been idle for a number of years.

do you think it is blocked with dirt or rust?

you could try filling the tube with wd40 or the like and let it soak for a few days and maybe try
using an old speedo cable (not sure if it will go around sharp corners) in a drill to
remove what the wd40 has loosened and repeat.

Hi,

brake fluid wont do much for you.

If the tank is smelly like old paint thinners then try putting fresh fuel into it and see it dissolves black gummy residue, otherwise try Automatic Transmission Fluid as it may get through the blockage and loosen it if it is dirt/rust.

Hi
I cut the whole bottom out of my fuel tank , when you looked in the filler tube it looked like someone had hit it with a shot gun ,the tank was like brand new except the floor , anyway what I'm getting to is that there is a filter on the end of the pick up pipe with a hard bottom on it , it sucks through the sides so you may not get a speedo cable or wire all the way through , I removed my filter , I'm going to run a extra inline filter out of the tank

Hi Malloch1
I had the same problem as you are having I tried everything to unblock the lines but in the end I took it to a Radiator Repair Shop who unblocked it as well as doing
a pressure test on it which showed up some very small holes that he repaired
I also did what Cheezle did and took the tank filter out and put in an inline filter
and everything is running very well
