I'm the new proud owner of Tom's old track car (914/6 2.4) and I'm getting ready to club race it (SWMS in ABQ NM) and I have a strong gas smell in my garage with it in there and trying to run it down. I know the fuel cell bladder was well inspected and got new foam last year and is using 2 older (pre-2013?) Mallory electric fuel pumps (pics below). I've read the smell can come from them and I'm looking at rebuilding them but cannot tell which model they are and asking if a member recognizes which they are?

That completely cured mine. My tank vents my fuel in the tank dry and I don't smell anything. Before I installed the off switch I went looking for a leak every where, I found a couple of places that were wet and fixed them but when everything was dry I still smelled fuel. I kept sniffing around the tank but it was not the source. It was the carbs so I installed the switch. The fuel lineholds a miniscule amount of fuel and tightening up the connections stopped the wet spots. Now I smell gear oil like 90 weight. But it doesn't bother me. My fuel tank is made for a drag boat and is conical at the bottom. With a very large vent at the top. It seems to breathe fuel cause it's always dry.

I've also read it can be the fuel pumps (membrane in them) but cannot see any clear evidence of that. Their race Mallorys... |

Mine runs a Holley. I'll snap a pic when I'm in the garage next.
When you have a minute could you post a pic from further back of the bracing in your front trunk? Mine has had the bulkhead wall cut out too but no reinforcement. That's a project for this winter on mine. Thx. |

Thanks!
I'll uncover mine today and get a snap of the FP. I'm planning a fuel cell swap this winter and while that's all apart it's a good time address some stiffening issues. -C |
