Hello Everyone,

Is this fuel pump setup on VP 5.0 GIPEFS normal?
A friend of mine told me it is a car fuel pump but I am not sure so I thought I should ask to see what ya’ll think. Pictures are attached.

Thanks!

No,

#1 No hose connected to the 90 degree elbow by the fuel filter, so filter is not doing anything.
#2 The low pressure fuel pump is not connected, open terminals at the base.
#3 Looks like someone put in a high pressure pump and connected the hose directly to the bottom.
#4 The return line from the TBI is connected to a non marine rated rubber hose. J30R7
#5 There shouldn't be a return hose to the fuel tank because the fuel manager recirculates the fuel.
#6 The return line from the TBI should be connected to the fitting behind the high pressure pump.

Ignorance is definitely a bliss. I have used the boat several times so far and I didn’t notice any fuel problems that I know of. But then I am a novice when it comes to boats.

What am I supposed to do? What are my risks?

you fix it right

or you could blow up


if a car fuel system leaks or sparks, the leak falls on the ground and the car has long since moved before it turns to explosive vapor. the sparks from a non-suppressed motor generally dont have vapors to ignite

in a boat, if there is a leak, it fills the bilge up with explosive fuel

all marine electrics must meet the SAE J1171 marine electrical code to prevent any sparks

first, never use anything automotive in a boat except long-block base engine stuff (that is the same)

however fuel systems and electrical systems must be marine.

Wow, NO it is not safe or original.

Someone has fitted a pump system for a TBI are you sure your motor is 5.0 GLPERF not 5.0 GiPERF?

This is what you should have http://www.marinepartseurope.com/en/...8-23-6922.aspx.

This is what would be fitted to a TBI system http://www.marinepartseurope.com/en/...-23-35164.aspx

Yes, I am sure its 5.0 GIPEFS unless the previous owner somehow changed the engine with something he was not supposed to as well...hmm so maybe I am not sure afterall

None that I can see or know of. Every day I discover something new about this boat.

It is very fuel efficient though. It uses less gas than I expected, I don’t know why. I had some old fuel in it, and considering how fuel efficient it is, I talked to a friend of mine who is more mechanically savvy when it comes to boats and he said it was automotive. Otherwise, I wouldn’t have known. I have had it on running for several hours so far and it has been running well. I recently changed the entire exhaust system, thermostat and so many other minor things. Now I have to change the axle and entire disk brake system as well.

Having said that, is working on the fuel system a DIY thing?

Also, at this point, I am financially, mentally and physically exhausted constantly having to fix things on this rig.

Is this something that can wait until next year to change? I need some good advice here please.

No if you have non marine automotive components in an inboard boat, either you fix it or stop using it. Ever seen an inboard boat that caught fire or blew up? It ain’t pretty. Given what you found I’d also be checking the alternator, starter and distributor to make sure they are marine spec. This is exactly why people who know boats usually don’t buy another old one after their first. They learned that boating ain’t cheap, a lot can happen in 10-15 years; you wouldn’t buy a vehicle that old for your daily driver would you? Try to find the VP sticker with the model # on it to be sure of what you are supposed to have and post up pics of the fuel system. Personally I’d never ever buy another old boat. Once was enough. Next boat will be nearly new, 3-5 years old max and outboard powered.
