Need photos of electric fuel pump mounting - Thanks!
 

I have a 1998 35 fountain. I am converting from mechanical to electric fuel pumps (holley blue). If anyone can post some photos of how there electric pumps are mounted in the bilge it would be great help.

Thanks again,
Joe Mattioli

I have mine mounted on the forward bulkhead in the engine compartment. PM me your email and I will send a pic.

Just sent you a PM....

I run a return style fuel log with a built in bypass regulator back to tank, holley black and oil pressure safety switch. ( kills pump when there is no oil pressure) In order to prime pump I have an override switch in the engine compartment to prime carb after layup.

Electric pumps don't last very long in deadhead setups IMO

Edit, you will need at least a holley black for the motors in your profile

On further thought, what was the problem with the KE setup?

Wobble,

The mechanical fuel pump was a Mr Gasket 7732....discontinued. The holly replacement dimensions are too big and it bumps against the sea pump. I can't find a rebuild kit for the 7732 either. So electric seems to be the new....but I bought the holly blue...the specs looked that same flow (130GPH @9psi) as the original pump.

Thanks for your comments...I will run a return line at your suggestion. Do you have any photos of your install?

800 hp u better go Black w/vent tube

Fuel pump wants to be as low as possible but above the top of the tank (to prevent siphoning in the event of a pump failure) holley offers a marine electric pump with a vent tube

I found this setup keeps the fuel cool, offers consistent fuel pressure at any demand http://www.jegs.com/i/Mallory/650/43...FaQF7AodmEgAiw

it has ports for a mech gauge, mine also has a low fuel pressure switch tied into the alarm system and a sender for a gauge on the dash

That Mr gasket Pump was probably an Edelbrock or etc 6 valve pump (most look the same) with a tube pressed into the 'bleed hole'.

Here is the Mr Gasket:

and The Edelbrock

Don't think the edlebrock look like that anymore,

but claysmith is still building theirs http://www.claysmithcams.com/big-block-chevrolet/

looks like you could use this. oops, will need regulator

I'm going off of memory, and since I'm old as dirt, my memory goes back a few eons. It almost seems like yesterday I was battling Dinosaurs for food.

I'll try to find something more current.

6 valve pumps where very good and dependable. Would be a shame to switch over to electric.

I would love to stay mechanical.....But a replacement pump would need the same physical dimensions and the same high fuel flow rate (130GPH/9PSI) as the Mr. Gasket 7732....

Wobble !

You are a life saver! The clay smith pump will work and they claim its a higher flow pump than mr gasket! Same dimensions and i just ordered it!

thanks again!

You are welcome, I went through mechanical fuel pump hell with my jetboat, the cam was so aggressive that it was causing the fuel pump rocker pins to fail (harmonics from the flat tappit cam) I have a box of busted ones, all brands I need to toss out. That's what sent me in search of a good electric system.

The clay smith may need a regulator to cut it down to 7psi so beware.

Already has regulator with the old 7732 pump..I assume I can just leave the setting where they are.....bu twe will check anyway.

BTW, the reason I mentioned the Black pump is because you lose significant gph on electric pumps when you pump through a regulator, that is why I like the return style regulator. The electric pump can run at rated output when the demand is there and when it's not it bypasses back to the tank.

Basically the same setup a lot of fuel injection systems have adopted.

This is not such an issue with mechanical pumps though still somewhat true.
