Chris_B Posted October 30, 2017 Share Posted October 30, 2017 I am installing a Carter 504 electric fuel pump in my 02- not because I think it is a great idea, but I was laboring under the misconception that it would make my life easier when working on my dual sidedraft setup. I had been using Cannon manifolds, which positioned the front carb such that I had to remove the fuel pump whenever I wanted to remove the top cover of the carb (e.g., when checking float height). I decided to nuke the Cannon manifolds, primarily because they are designed in a way that prevents syncing the front to rear carbs. The rear manifold is canted up (I would guess to help it clear the brake booster) such that it is impossible to link the front and rear carbs. I tried to modify the linkage to make this work, but could not. Anyone with dual sidedrafts know how important it is to balance the carbs. IE came out with a single piece manifold and I bought one and am installing it. Now that I have installed the manifold (see pic), I find that there seems to be plenty of clearance to remove the top of the carb. Anyway, I am committed to install the electric pump. Here is my question. The docs that come with the pump say "DO NOT INSTALL IN THE TRUNK." Yet, in searching on the list, I see that many people have installed pumps in their trunks. I understand that the concern is that if there is a problem with the pump, a hose or there is car crash, etc. that would be bad thing. I am wondering if any of you or anyone you know has ever experience a problem because of a fuel pump installed in the trunk. Here Quote Link to comment Share on other sites More sharing options...
Simeon Posted October 30, 2017 Share Posted October 30, 2017 I would install it underneath the car just in front of the tank if you are concerned but either way, use an automatic safety switch that cuts supply in the event of an accident.

Dudeland Posted October 30, 2017 Share Posted October 30, 2017 Pegasus has an inertial switch that you should use in case of an accident it will disconnect the power to the pump. I am about to install the same pump, for different reasons. I want to have the fuel line outside the main cabin, and also be able to control the fuel pressure. Also I will install a canister type filter for the fuel filter along with a return type regulator. The point is to keep the fuel outside the cabin, and away from impact points. Keep it underneath the car and in the middle so if you get hit, there is less chance of it spilling fuel all over the place. https://www.pegasusautoracing.com/productdetails.asp?RecID=87 Quote Link to comment Share on other sites More sharing options...
Son of Marty Posted October 30, 2017 Share Posted October 30, 2017 You can get a a inertia switch off any F/I Ford product at a Pick and Pull near you for a couple of bucks, the challenge sometimes is to find out where Ford hid it in that particular car model and year.

Carlc939 Posted October 30, 2017 Share Posted October 30, 2017 I have that pump, mounted it just to pass side of the brake booster in engine bay, used a relay, didn’t want pressure on an ancient plastic hose, a little noisy, works well.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Chris_B Posted October 31, 2017 Author Share Posted October 31, 2017 So, this pump will pull fuel to the front as well as push? Quote Link to comment Share on other sites More sharing options...
TobyB Posted October 31, 2017 Share Posted October 31, 2017 The pump would really rather push. Quote I am wondering if any of you or anyone you know has ever experience a problem because of a fuel pump installed in the trunk. I put one in the trunk and had a problem- water leaked in, the pump sat in it, and the thing stopped working. But no fire, fuel leaks, etc. As to the Ford switches, they're usually in the trunk, driver's side, and there's usually a yellow notice explaining that it's back there so you can reset it if need be. Note the installation angle- I think all that really matters is that it's mounted exactly vertically. They're cool. t Quote Link to comment Share on other sites More sharing options...
eurotrash Posted October 31, 2017 Share Posted October 31, 2017 I mounted my carter 4 psi pump under the car, above the diff and used the return line as feed. After two pump failures, I am tired of the thing being hard to get at. I am working on a trunk mounted, switchable, redundant pump solution. And because I spent real money on better gear, I will probably never need the second pump. Quote Link to comment Share on other sites More sharing options...
Chris_B Posted October 31, 2017 Author Share Posted October 31, 2017 How will you control the output pressure with this setup? Quote Link to comment Share on other sites More sharing options...
