I'm putting a fuel cell in my '89 Cavalier (new track requirement) & I'm not sure what external fuel pump to use. Anybody else have this situation that can give me some ideas? I've heard that its possible to use the stock in-tank fuel pump but how would you mount it in the fuel cell? Also is it necessary to have baffles in the fuel cell?

Wannabe,

Are you still using a throttle body? If you are Holley makes a good external pump that puts out 15 psi and expensive, I used to run one my S-10 until I switched over to a carb. I now use a Bug Pack which has worked out great. It's preset at 3-5 psi and only cost $35.00. Hope this helps.

go to your parts store and tell them that you need a pump that will be inline but put out the pressure that you need back when I was working at a parts store We had a book that listed all the pressures of the universal pumps. Good luck BObby

You can use the stock one pretty easy.We drilled a small hole in the tank and put in a boat bulk head connecter to seal.(I have seen guys just drill 2 small holes and silicone the wires,not recommended)The easy way is to get a ford high pressure pump from a 150 that mounts on the frame,just make sure you mount it as low as the bottom of the tank,we bolted ours right in the front of the fuel cell on the framrwork.Also you can use a Volks Rabbit inline pump

Thanks 4b316. I think I'm going to go with the F150 like you reco'd.

I am mounting the fuel cell in the trunk behind the driver's seat. I still have to put a firewall in & my rules require the fuel lines to be inside conduit if it passes through the driver's compartment. Is this the way to go or should I route down to pick up existing fuel lines from gas tank?

I really appreciate your help.

Run it thur the conduit,it will be alot easier.You are going to have foam in the cell?You don't have to mount your cell in the middle of the car behind the driver?

4b316,

I thought I needed to put foam in the cell but have since found out its not necessary(I'm just getting started with this racing stuff, so I probably ask some stupid questions from time to time....but I figure if you don't ask then how you gonna ever learn.)

As far as mounting the fuel cell, all my rules say is that it has to be in the trunk area not necessarily in the middle. The guy I bought my car from is a pretty good modified driver & he sort of recommended that I might try mounting the fuel cell as far on the left side as I could get it. This seems to make sense to me to counter the body roll that's going to happen when I'm cornering anyhow. Of course he's working with rear wheel drive not FWD but wouldn't the same principle apply?

By all means,if you can mount it anywheres you want,I would want to put it behind you and as close to the left as you can.You should run foam in the cell as this helps fuel slop.In a FWD you want to get all the cars weight over the left rear,moving your seat back and keeping your cell over the rear axle.

Hey guys,

I've got the F150 fuel pump in hand & I'm ready to mount it like 4b316 recommended a while back. I'm planning on mounting it on the frame rail running just below my fuel cell & hooking in to existing fuel line that I'll pull off the gas tank. I'll pull the existing return line off the gas tank & extend it to dump back into the fuel cell. Is this the right way?

Will I have to prime the fuel pump to get fuel running up to the engine or will the fuel pump pull fuel through when it starts pumping? (all the fuel cell has on it is a hose running down in the bottom of the cell; no sending unit) If I have to prime it, what's the best way to do it?

I've actually got the whole fuel system from an F150 including in tank sending unit & fuel bowl but I don't plan on installing them if they aren't necessary.

Any help would be appreciated.
