Electric fuel pump
Somebody give me a suggestion for a good electric fuel pump. The motor is a stock 350, but the truck was diesel. When PO got the motor, he got a commercial grade motor and has no provision for the mechanical pump. I have bought two already, both from Orielys, one being a MR GASKET and the other , not sure, of the brand. Anyway I am tired of replacing these pumps, I can't do anything else to because I am trying to keep it running all the time. I almost bought a distributor today untill I took it apart and had the module tested, it was fine, put it back in and still no start. Pulled the carb EDELBROCK 1405 and was dry as a Bone inside. That led me to check the fuel pump. I turned it on and it won't even pump the fuel. I NEED ONE THAT WILL WORK FOREVER !!!!!
JEGS has a couple, I'm gonna call them tomorrow. I thought about getting a tank from an 87 or newer wih the internal ump and put a regulator, what do y'all think Posted via Mobile Device

Re: Electric fuel pump
How and where do you have the pump installed? Maybe its too far away from the tank and its having to work to pull the gas and that's causing it to fail prematurely?

Re: Electric fuel pump
I had the same problem with the auto parts store ones. I would say do an intank one if you can. They are much quieter and are suposed to last longer. Areomotive are some of the best. Not cheap but they are reliable.

Carter P4070. They're simple, proven, and run forever.

Re: Electric fuel pump
Could also install a stock in-tank sender and TBI fuel pump, use a regulator to bring down the fuel pressure to where you need it.

Ditto on that, But use a bypass style regulator. I went through 3 different brand inline pumps on my 97 in 4 months (yes they were mounted correctly) and said heck with that, Put a TBI tank-pump in with bypass regulator and been running 3 1/2 years now.....

Re: Electric fuel pump
Carter pump, it will last....for a while. They are positive displacement pumps rather than a gerator, so they are noisy, and not rebuildable.
My advice would be to buy 2 and carry a spare in the truck so you aren't stuck on the side of the road. |

Re: Electric fuel pump
I've ran a Carter for 13 years on my truck without a hiccup.

Re: Electric fuel pump
For an external pump setup I prefer Mallory.
Your store bought pumps are cheap to buy, but are cheaply made and sound like a weed wacker when running. The Mallory pumps are a gerator design much like an oil pump so they run quiet. It's also a perminant magnet design so you don't have to worry about the glued on magnets falling off in the cheaper designs (I've had that happen and leaves you stranded) Seems the glue (yes glue) only lasts so long and the magnet comes loose. Not a problem in the Mallory units. Best part is they are rebuildable. I run a Mallory on 2 vehicles, one has had the same pump for 18 years. The other is fairly new. Alot of things contribute to pump longevity. Having a restrictive filter before the pump hurts pump life. If you run a filter before the pump, make sure it's a big one Not having a large enough suction line can make the pump work harder. I also prefer to run a return style regulator (never dead head) so the pump isn't under a strain and it keeps the fuel circulating from the tank to the regulator (mounted as close to the carb as possible). This also keeps the fuel cool since it's not sitting stagnent in the fuel line. No more vapor locking issues. For your application a Mallory 110 would be more than enough. You'll probably spend $3-400 for pump and regulator. I believe some of your Holley pumps have since switched to this same Mallory design on some of their models too. If an internal pump is desired, what these guys are suggesting would work. Alot of good setups out there when going this route from factory to aftermarket. Even these setups won't last a lifetime, and pump replacement is more involved when the time comes. |

Re: Electric fuel pump
Anybody ever use an airtex pump?? I have one for my tpi setup. Just wondering if I should be making plans for a change. No problems for about a year now..But I am wishing that I went with the tbi tank and tpi pump based on what I'm hearing.
I had the darn tank in my hands... |

Re: Electric fuel pump
After getting a good quality pump, the other thing you might try is to run 2 pumps in parallel; This way if one fails, you can just flip a switch and keep driving.
Will post a diagram if i can get it together (not likely as i have numerous spiritual, psychological, and physical[working 3rd shift lately], mental, and emotional problems at the moment.......) |

Re: Electric fuel pump
x2 in tank pump. As long as you don't run your tank empty of gas the gas will help to cool the in tank pump and prolong its life. They are a pain to replace but dropping the tank is not that hard. An OEM in tank pump should last several years easy.

Re: Electric fuel pump
Sorry guys, have been on in awhile. It does start when I pour gas in the garb, that's how I found the pump had gone out AGAIN. I almost went and bought a new distributor but process of elimination prevented that. I still have not installed the pump yet, but will today. As far as how long it will last, I don't drive the truck everyday, in fact, still trying to make it roa worthy, but wanna keep it running. Still have to replace/remodel the whole interior. Next thing to replace the the HARMONIC BALANCER. it has a small one on it and suppose to have the big 8 inch one. I really don't know if that will make any negative effect on how it runs, but I don't think I am getting the timing right with it.
