Fuel Pump Question, tech question Options

[BadToTheBown]

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?

I'm only guessing... look like holley low pressure maybe...

but the fuel smell could easily be coming from the carbs.
if the car has ran in the garage... then the 4 fuel bowls are full to the carbs... I sometimes drain the bowls. mine will evaporate completely in about 24-36 hours into the atmosphere on my -6 in the garage

Thanx for the follow-up. They're Weber 40 IDA3Cs, I have a lot to lean about Webers, not to mention Porsche boxers, are the bowls hard to drain and I'd be interested in some pics of how you painted your car, I might make some changes to mine and looking for ideas...

Especially if you are running pump gas, draining the float bowls is a good idea when the car sits. Today's pump gas gums up carburetors.

This may be what Brant was saying, but another reason for gas smell on a carbed car - if you run the fuel pump for a while with the engine off, gas will overflow from the float bowls and start dumping into the engine. This isn't great for obvious reasons, two of them being gas smell and potential fire hazard.

Nice purchase, by the way. I noticed the car for sale and thought it looked like a good deal. And welcome to 914 World!

Thanx and Tom's a great guy. Wish we could hang out but he's 2 state too far away.

They are 2 low pres pumps, looks like 4 lbs on 1 pump and close to 9 lbs on 2 pumps. I'm still figuring out why I have 2 pumps. I see 4 lbs for idle (to not overcome the bowls) and I can see 8 lbs for WOT but I think I need a lot more HP to need the 2nd pump. This engine probably only makes 180 or so HP.

I don't know how to drain the bowls (is on pump gas, 93 octane), so I'm guess I'm going to learn, thanx...
