fuel pump recomendations ?
 
I need to replace my failed Carter electric pump.
Single Holley double-pumper, single engine (about 500 hp), Max RPM 5800.
What do you guys recomend?
I`m thinking that I`ll upgrade all lines to 1/2" and install a regulator for sure.
I`d also like to possibly install a fuel psi gauge on my dash, anyone done this?
Thanks for all replies!

500 h.p. don't waste your money on 1/2" line unless you plan to go bigger in the future.

I ran twin Mallory marine pumps on my cat. They were wired alternatly so only one pump ran at a time. After around 50 hours of use, both pumps were showing signs of failure. This is pretty consistent with other members experience with electric fuel pumps. These things just do not live. As much as I hated the extended crank times with a mechanical pump, I'm thinking that is the way to go. Perhaps a check valve could be added to prevent the fuel from draining back.

My Holley's didn't even last that

I had a Holley pump at first. It lasted maybe a total of 6 hours. I bought this Carter about 3 seasons ago. I have put about 125 hours on it. It still pumps, but is weak, shows 3 psi on gauge.

After two Holleys I went to an Aeromotive marine pump with a bypass regulator. The bypass was an extra hassle to set-up. Should have the boat out this weekend.

Where did you buy the Aeromotive? ...and how much $$$ did it cost?

REX Marine had the pump and regulator. Bonaco.com made up the stainless lines for the regulator.

The whole thing was about 450 dollars.

Well I have over 100 hours on my Holley's, still pumping very strong regulated down to 6 lbs, but they are mounted lower then the tank they are always wet!! (with fuel). that may help!!

P.S. I would run 1/2 iinch lines now because if you are like the rest of us boaters you will add more power sooner than later!! goes with the territory

I use the weldon 600 pump. I only have about 80 hours on it so far, but it has worked perfectly. Runs silently and weldon said that they have one on a test stand that has been running for over 2000 hours continuously with no problems. It looks good too. On one side it has some Japanese writing on it, I asked what it said and they told me "made in America". Not bad pricing either, about 375.

Where do you buy Weldon pumps?

What are the specs for the 600 model?

summit racing has a 150gph aeromotive for 165.00 its a great pump no bypass needed just a good regulator. heres the link most bang for the buck

Having the fuel pump below the fuel level is a requirement for these pumps to live. They simply are not able suck the fuel up out of the tank. The problem is that mounting them low like this is very clearly a Coast Guard violation. You can not create a situation where the fuel will have an opportunity to siphon out. Having the pump low in the bilge creates this situation. The best solution would be to mount the pump in the tank. Aeromotive might have a in-tank pump, but I'm not certain.

I run a holley black marine with a return style log with built in regulator. This allows any excess fuel to return to the tank. Has worked great for 3 seasons. delivers 5 gallons in 2 minutes 20 seconds at carb height. Pump mounted in bilge.

Dead head regulators seem to kill electric pumps in short order and dramatically reduce their fuel delivery rates.

I am using a gaffrig fuel pressure sender and guage.

Been using a Holley Black for two seasons with no trouble. With the rep of Holley I suspect I have been lucky thus far. I plan on replacing it this winter as part of PM. Anyone using the Aeromotive SS?

Should be a good product.

A buddy put one on his jet boat, lasted about 16hours. They did repair at no charge however.

put on Holley reds at the beginning of the season and have about 20 hours on them no issues yet.

Re: fuel pump recomendations ?
 
I may be wrong, but as I recall, the weldon 600 can be mounted "above the fuel tank without concern" according to weldon. I bought mine from Kinsler fuel injection in Michigan. It does need a bypass regulator though or it will run the pressure up to about 250 psi if deadheaded.

I routinely use mallory marine pump's, sometimes regulated, most of the time the 9 psi pump with a regulator. more affordable than the weldon, wich is a great pump but for higher hp applications and they do make some noise.Aeromotive is also good but stioll a lil pricey, and your not making much power. -10 line from tank to pump. -8 from pump to carb. this reduces aeration and high fuel temps from using small diameter fuel line. always use radiused 90's, not machined.

good luck

I went with an Aeromotive pump, bypass regulator and filter. Mostly due to availability and price. Received yesterday via UPS.
Thanks for all replies!
