Hi All, I already have an electric fuel pump I got a while back from Napa. It works very well, and I have never had any trouble with it. The thing is, it is too noisy. I know that since it is not an in-tank pump it will be a little louder, but this is annoying. Does anyone know of a particular brand that is pretty quiet, and works well. Also where should I mount it? I have mine on the frame rail, and I assume that is fine. Keep in mind, I have a carb, so I only need around 6 psi. An internally regulated one would be the best, but I can always get a regulator. The reason I need the electric is because I have a late model 5.0, converted back to carb, and it lacks provisions for a mechanical pump. I would love to have a mechanical pump, but I don't think it is possible, unless someone knows a way to do it. Thanks. -Corbin
Pump You may have to insulate it to quiet it down, rubber mounts and the like. Probably some quiet ones out there but I have always used Holley's and they are loud even on drag cars with open headers. You can change the timing cover on your 5.0 to an early model and incorporate the fuel pump eccentric onto the cam. About a 4hr job maybe. Thats why I get all the covers and stuff from salvage yards and rat hole them. Sold a few on eBay for a substantial profit.
hi corbin, sorry but all i can do is add to what oldguy said. i have a holley on my 71 and it is loud. i first thought there was a problem so i put a new one on. no difference. maybe someone else uses one that is quieter. good luck.
Thanks guys. I guess all I can do is insulate it, and hope for the best. Thanks again, and I'll let you know what happens. -Corbin
I run an electric on my Sprint and I cant believe how loud it is. I started with a Holley and switched to a high priced Paxton hoping it would be quieter. It wasent. I've tried mounting them on thick rubber and even made a mount that suspended the pump on a rubber frame. Didnt make a bit of difference. Even when just suspended by the input and output hoses, its still unbelievably loud. I was going to post this same question hoping someone knows of a quite unit.
I'd say mount it back by the tank but even then it'd probably still be loud because it's not inside the tank. My car once had an Electric Fuel Pump mounted on the left shock tower, when I got the car it was using the mechanical one and the electric one was still in there dangling by one bolt not connected to anything, it's shot so I couldn't use it I'm thinkin about buying another one and putting it where that one was simply because electric pumps are self priming. My Mechanical one works fine it just needs a kick in the a** once in awhile. As for it being quiet I don't think there is such a thing but I look at it this way i'd rather be able to hear it this way I know it's working if you stop hearing it then you know you're in trouble.
Well, I decided to keep the electric fuel pump. The pump I got at Napa is a Facet one, and lots of people really, really like them. I have never had any problems with it either. They say that with the pump I have, rubber insolators quiet it down. I am going to try that this weekend or sometime when I have some time. I'll let you know how it goes. -Corbin
couldn't you use the timing chain cover off of a 85 302. Same motor only carbuerated. Then you could use the mechanical pump
Yeah, I was thinking of that, but right now I don't want to take it all apart. I just got it all together. If I do a cam change I might, but that would be in a while. Thanks for the suggestion. -Corbin
Corb, just some thoughts. If the pump body radiates the noise directly, mounting on rubber won't do a lot to quiet it's running. Perhaps some kind of insulation applied to the pump will help dampen the situation. On the Lincolns, there is an air pump and a brake pump that reside just ahead of the driver. They can be heard running by people with good hearing but is not at all objecional. I think if you put your hand on the pump while it is running you may feel the vibration right on the case it's self as opposed to just general vibration.
Ken, I was thinking about that, and I think the most annoying thing about it is that sometimes it changes to almost a rattle. I think the mounting plate is not flat so it rattles sometimes at certain rpms. I would like to insulate it also, but I don't know how to do so. I guess I could mount a box around it. I don't know if that would work well or not. Anyway, thanks for the tips. -Corbin
i try one of the mallory ones. i have a holley bule on one of my cars and its loud as heck.. you can still hear it over the 3 inch flowmasters... however on my othe car i have the mallory and its quite. my dad also has the mallory very quite too! i never was a fan of mallory but i have never had a problem with it. good luck on what ever you decide
I'll look in to that. Thanks for the tip. If it drives me nuts, I might have to switch to one. -Corbin
I have two Carter street strip eletric fuel pumps. The one on my mustang is quiet but the one on the maverick is noisy. What pisses me off is that it's noisy in the morning but the longer you drive the quieter it gets until it's like the mustang. I have no idea why, they are both rubber insulated mounted next to the tank down low. The power connectoin is good along with the ground. I know the sound well and one day I'm going to fix it with a hammer buzzzzz buzzz my blank!!! One thing you might want to do is put an inertia switch on the power wire that way if you get hit the pump will stop, it also helps when you do maintenance, tap it with a screw driver and the pump is off. I got one a the wrecking yard off a tempo, it's in the trunk on the drivers side behind the wheel well panel.
I have a holley blue pump.its mounted on the frame rail with 1/2 '' rubber isolator about under the back driverside seat.its also loud .it also vibrates some you can feel it in the drivers seat.i dont let my girlfriend drive it she might leave me and take the car.lol
