I see you have a Kadey Krogen you probably have a Ford engine.
In all my days I've never had a lift pump fail, the only possibility you may find with the Ford is if your engine oil level begins to rise.
That could either be, a perforated diaphragm on your lift pump but the engine will continue to run as normal, or, the other cause is the excess fuel lines between the injectors under the rocker cover sometimes crack at the brazed joints.
If you have the sandwich type CAV fuel filters you can buy a conversion kit with an integrated hand primer and change them to 'spin on' canister filters.
When you wish to change your spin on fuel filters get a quart of diesel in a bottle,a plastic bag and some rags.
Run your engine until warm, then place a plastic bag around your old filter (to catch any drips) and remove the filter. Remove the old rubber sealing ring, wipe it with oil/diesel and replace, then carefully fill your new canister fuel filter full of diesel from the bottle and carefully spin it on hand tight, wipe it clean and then firmly hand tighten again.
If you've done it properly your engine should start on tickover without bleeding, if it stops push the hand primer until firm and then start the engine whilst pushing the hand primer.
There's absolutely no need to fit an electric pump. K.I.S.S.
Wipe everything clean, wash your hands, job done now you can pull the top off a cold one.
