mounting electric fuel pump

[brian72]

I plan on getting this pump..http://store.summitracing.com/partdetail.asp?autofilter=1&part=CRT-P4070&N=700+115&autoview=sku

Question1 - is it best to mount on the inside or outside of frame rail?
Question2 - is it best to mount closer to the tank or closer to the carb?

Here is how I mounted mine...same pump.

 

[BigFord74]

I was alway's told inside of frame to help keep protected. ANd was told to mount as close to tanks as possible. I've put 2 on 2 different car's and both i've mounted under the hood. Mainly cause at the time it was a temp fix and i didn't want to drill any holes at the time. Both worked great, so great i forgot to move them till you asked the question LOL.

Yeah, I was told by my dad (a mechanic) the same as BigFord heard. The reason is these pumps are designed to push the fuel, not pull it. When I put mine in, it was as close to the switching valve as I could get it on the inside of the frame rail.

if you have dual exhaust, i'd say outside the frame. you want it as far away or shielded from the heat. running single exhaust, inside for the protection.

Brian,

Mount it inside the frame rail on the driver's side. Try to get it as far back as possible, because it needs to be close to the tank....and the damn thing will probably make some noise. I've done all of mine this way, and some (not all) have been irritatingly noisy. There's no way to tell until you fire it up and test it.

Also, you want to drill and tap the frame so that you can bolt this thing in ....instead of using screws.

If your exhaust is within 2" of this unit, I would sugegst fabricating a small heat sheild out some axtra metal you have lying around.

Near the tank reduces the chance of vapor locking and inside the frame helps protect it. Keep it ways from the heat as well though. On my pump I actually have it mounted on top of the frame. (The bracket bolt in from the side)

That's why mine is outside the frame. I origiannly had it on the inside and had major problems with heat.

Inside the frame if the exhaust is not in the way keep it as far as possible from heat thats what kills electric pumps I have the carter pump also 25+ years with no problem and they are pretty quite but you can hear them

As others have said, I would mount it to either side that works best for you. The better place would be inside, as close as possible to the tank. As was mentioned, noise factor, you might be able to use some flat rubber on the mounts to help deaden the noise from the pump. Heat is another issue, if you are near any sort of heat source that may give off more than you wuold like, a starter wrap or something simular to it would be advised. Also don't forget to put a filter between the pump and the tank

---- I mounted it on the outside of the frame rails cause it's a hot crowded enviroment between the frame rails with dual exhaust-- I still need to build a little skid plate from the rail to the leaf spring mount for max protection---reason the pumps a little low is I wanted a downward slope after the fuel exited the tank--

I guess if I am running dual tanks, I either get two pumps or mount is as the fuel line exits the switch valve?

 

[MarsChariot]

With a piece of sheet aluminum and some work bench metal fabbing and you can make up a small heat shield that will let you mount it where you please (or can, as the case may be). I did one in order to shield mine from the passenger exhaust pipe aft of the Dynomax. It is mainly radiaant heat, rather than convected heat, that matters at short distances. This one seems to do just fine. The Carter pump can’t see the exhaust pipe and is happy.

1 pump works fine and yes plumb it in on the exit side of the switch been running my carter 4070 like that for 25+ years without a problem. Just put a filter on the intake side of the pump that will help it live longer.

I mounted mine on the rear cross member of the frame just in front of the rear tank. I also ditched the original valve and went with an electric valve. I don't have any heat problems and I can't hear the pump. The HP pump under the hood is another story...

 

[SaddleUp]

Just be careful with mounting it in front of the X-member. It can get close to the rearend there.

What's the advantage of electric over manual ? Sorry for hijacking your thread.

This is where I mounted mine, minus the bracket. It does not appear to have any clearance issues but you would want to double check.
