Sounds right, do a search there are lots of posts.Best drop the tank to change it and check/replace the rear brake pipes while you have wash access

Sounds like there is a hole in the pipe and it's sucking air in or some carp floating on the surface - may have to pull the tank pump to check it, it's pipes and the end that 'sucks'.

I replaced mine some years ago. Dropping the tank looked like a pain : I think I followed some advice on here and cut out a panel in the floor above the pump. Job was dead easy.
Have a search for the thread .

But you cannot check/replace the rear brake pipes through the hole.Dropping the tank is no biggy, as long as you run the fuel level down as low as possible.

As said above drop the tank, at the age of the p38 now if the brake pipes have not been done they probably need doing, and you don't want them letting go at the most awkward time.

Problem is, he can't run the tank down below half.
Anyone know if there's a drain cock on the tank?

No drain and if he syphons it there will still be fuel in it. When i did mine despite best efforts there was still around six gallons in when i dropped it. It's difficult to get the syphon pipe passed the surge valve.

No. Getting the fuel out was the longest part of the job for me. I had to go borrowing jerry cans because I ran out. It is a BIG tank!

The big marmite question is:
Did you cut the floor or drop the tank?

You think he'd admit to butchering his pride and joy online and risking his life with dodgy brake lines?

It was kinda an 'all sorted gotta run can't speak all fixed must dash can't hear you mate' reply.....

Actually, on mine and the earlier models with only 1 exhaust the brake pipes go across the axle which is so much easier! So his '97 is probably OK.

Drop the tank!!

inchil1963 · Jan 23, 2018

Booo. Hiiisssss!

I must admit when I have to drop my tank to do the pump and brake pipes I am considering cutting an access panel and making a nice swaged cover panel fixed with rivnut inserts and a seal while the tank is out.
