What Kind of Fuel Pump???

Well the forums been sort of dead for a few days so I thought I'd try and get some conversation going.

What sort of fuel pumps is everyone running?? I would like to hear from both aircraft and car motor guys here...no need to be snooty I guess :p

I use a Faucet electric pump on my 470. Ran great for a few years until New Years Eve. I think I'll go with a Carter next time though. They seem to be a little more inexpensive. I can have a primary and spare for a little more than a Faucet.

So what you got???

Here is a long answer to a simple questions. I used to run the Holley Blue on my 0540 angle valve. However, when the motor was rebuilt I purposely had a new accesorie housing put on with a mechanical pump. I recently found (while doing a paid airboat ride no less) that the vain style Holley blue will not allow for proper flow through when not working. I now run a diaphram style pump in conjunction with the mechanical. It should be noted I was able to get home when the holley Blue died I just could not run real hard.
 
Well guys I appreciate the responses...I kinda already know that you are either running a mechanical or an electric...I was looking more for brands but hey, why be choosy, right. :p At least we're getting some responses.

On aircraft carbs, there is 2 pressure needle and seats. most carbs are the lower pressure 4-7 lbs, the high pressure seat is 15 lbs......I use a mechanical, with a fauct electric for priming, and carry a squeeze blub off a outboat as well.
On my fuel injection boat, it uses a 40 lb bypass type pump. carry a spare pump if by myself.
A good water fuel seperator is important as well. I use the cartrige spin on type.
 
Ran a mechanical fuel pump with a Red Holley electrical to prime a 540. You can run on the mechanical while the Red Holley is off. Mainly because JC Whitney, Jeggs, and Summit had rebuilt kits for it and I know someone that would do it for free.

I have been told it is a smart idea of carry what is needed to bypass the mechanical (just a brass nipple and hose clamps off the mechanical) so if it goes out, but you don't have to.

There is one of the old automotive mechanical pumps that you can install after cutting foot off. I would have to ask around which one it is.

Just make sure you run the electrical the right way through the mechanical pump. Tends not to work well (actually not at all) when plumbed the wrong way. Just don't ask how I know. :lol:
 
i run a $30 advance auto parts electric pump, been running it for years, this is on a six cyl aircraft. i always carry a spare though. this motor doesnt have a mechanical pump only elec.
 
Good post. I can get some ideas of what I might want for my 220 GPU to keep as a spare. Thanx . I'll be watching. Later
 
I run a Holly red label on my 520.

Cajun, for a mechanical on the gpu you can use a stock slant six dodge fuel pump. It bolts up perfectly and has good pressure but the volumne is better with the stock GPU pump.
 
To add some very important criteria to this thread, which I think is an excellent one....

Here are a few.

#1 Is your engine?;
Carbureted
Mechanical fuel injection
EFI

N2O Assisted
Turbocharged
Supercharged

If a Power Adder is used...How many stages of Nitrous, boost used, and if intercooled, is it water/air or air/air. If so...What is inlet air temp in relation to fuel temp? AKA what Air/Fuel ratio do you run?

#2 What is the rise (vertical distance from your lowest point to highest) of your fuel line?

#3 What diameter is the fuel line?

#4 How much ~HP are you/think you're making?

#5 What fuel are you using?

Once again this is food for thought, and HAS to be considered when modeling a fuel system from my Experience/Opinion.

barry grant 220 gph 1/2 inch inlet , 1/2 inch return and 1/2 to the carb . pressure 14# at the pump 7# at the carb on a 500 cadillac.
 
I have run a ton of different fuel pumps. A/C Delco, Holly Red and Blue, Carter, Jegs and a Mallory. Every pump has failed me accept for the Carter. In my experiences with a carbureted aircraft and car motor hands down the Carter is the best and by far the most reliable. I sunk a boat with a Carter and the pump still works fine after years of service. I actually still carry it in my boat for a back up and it his brought back several boats that lost their fuel pump. So for me I will never install any other pump on my boat other then a carter. The clicker A/C are the ones I have seen fail the most.
 
Took the words out of my mouth,Well said Water, Feel the same way.Carter all the way.I run an aircraft.
 
I am running a Carter electric to feed my 930cfm carberated GTSIO 520.
If my boat sits for a couple of weeks without running the Carter will loose it's prime and won't self prime without disconnecting the fuel line at the carb. I'm thinking of putting one of those outboard fuel line primer balls on the inlet side of the fuel pump. I have changed the fuel lines, filter, & even installed another new Carter fuel pump and it still does it.... :?:

If anyone has any ideas what may be causing this I'm open for suggestions.
 
Buck - Those tanks from Panther/Classic had the ball valves in the tank pickup. I knew of one that had some serious corrosion issues in the field and jammed shut. It was a bugger getting that off and the tank replumbed in the field. I think the boat/tank sat up for six months and apparently had water in the line.
