Fuel pipe route from PRV Update

[Robert Price]

Still a bit unsure of the route and joint position, the pipe from the PRV is vertical just in front of the lever arm shock, the long intermediate pipe extents with no bends well under the boot so where roughly do they connect? These pipes came from Rimmers so I assume they are correct.

Looking sideways at the wheelarch the long pipe coming from the front passes the vertical pipe from the PRV by about 40/45cm it seems too long hence my confusion.

Mail sent Waldi.

Colin you confirm my suspicions, I am contemplating attaching the longer pipe to the front and the MU one at the rear to the PRV I think they are just about the right length together. Despite a plier type pipe bender it is tough to bend well. Why suppliers cannot get this right I have no idea what a waste of money and time.

Hi Rob,

If you pm me your email address, I can fwd the pictures Stuart kindly sent to me.

In my case, the connection is in the vertical part, so the long horizontal section ends with a bend upwards.

Not sure if this is original, so I think if you start at the front with the MU flexible hose , and work backwards, it will be clear where your connection should be.

Just measured the 3 copper pipes part number 151229 40cm /16 inches, 149754 (mu pipe) 50cm/20inches, 308826 190cm/75 inches.

This totals 2.82 metres or 111 inches. The flexible pipe from the MU adds another 28cm/11inches.

 

This is far too long, it puts the end of the long main pipe about 18 inches past where it should meet the end of the PRV pipe!!! no idea.

Is this Peter Taylor drawing any help ?

151229 (item 66 which connects to 68 then 70 with DE unions connecting them) was the big seller back in the day - it is 'S' shaped and goes from the PRV, through boot floor to long pipe that runs forward. It corroded where it passed through the grommet.

Rob,

 

Some of the kits are too long. The longest pipe goes from the join at the front chassis, near clutch slave, all the way to the PRV t piece. This is an absolute pig to bend and get right. In the end I cut the pipe and created a join at the rear of the chassis by the trailing arm area. My kit had an extra length that i used to make the connection to the prv t piece. You'll need to swage the pipe to create the join.

Yes a devil to bend. PI saloon cars had a flexible nylon tube from PRV to MU (5/16" version of the injector tubes) - easy to fit but did not go round sharp bends.
