I'm looking for a brake line diagram for my 88 4wd pickup, while repairing the frame i disconnected the two lines that go to the LSPV and when i went to put them back, my marking wore off.

Also, when bleeding the brakes should i bleed the LSPV before or after the wheel cylinders?

I too am looking for a diagram for this same truck. I have a leak somewhere above the gas tank. I need to know what to expect.

I had the same issue. My brake lines were in very good shape except above the gas tank or perhaps a bit farther forward in areas not accessible. I drove the truck to a mechanic and they simply cut the line going into the inaccessible areas and spliced in a new line to the old ones. They did not have to drop the tank. It was a pretty easy fix for them. The mechanic said it is a common failure area as leaves collect there and the moisture causes the steel lines to rust. They did have a hard time bleeding the rear brakes because of the apportioning valve but that might of been caused by lack of knowledge. Not too many 87 trucks around and it was a muffler shop. LOL. Best of luck.

PS: I have the 88 FSM and will look for the diagram later today. Having video calls most of today with family since my boys all live in different states.
