Did you ever get your Kamotor flares mounted?? I'm seriously thinking about selling my DTM's and getting his extra wides..........

Are u black? Is it black? Maybe its racist?

[ballski]

Could it just be your gauge is bad?

that was my only thought also. It's brand new, but a cheapish one

Idk make sure the return line is coming from the proper port?

yes did that. It's labeled on the FPR also

Pump is all the stock wiring. Seems to be sufficant enough. Id say its less about your pump and more you fpr just not being able to go that low. Theres a dif between high pressure and low pressure fpr. Buddy is running the same mallory fpr as me with a walbro 255 on his sbc swapped 240 with a 750double with zero issues. Prob just gotta get a low pressure fpr. Mine is listed at $99 on summit right now and has 4 ports plus a return and you can run it with boost via the vacume port.

taking a stab at this because i'm not familiar with carbs, but..

the late model stock pump may run too much pressure for a carb. investigate using the low pressure transfer pump from early model e30's.

also the fuel pump relay wire for e30's is c101 pin 13. it's a green/violet wire. double check the ETM's for your particular model/year here

I have that wire running to the positive from the battery on a switch. But it's always on then. I was looking for it to only be on with the ign switch. It's an 87 so I'm not sure if it has a secondary pump? Ha

Have to run an adj fpr. The holly regs are crap. Also do you have the return line hooked up? I run a mallory 4309 with a holly blue pump and the return line hooked up. You want 6-7 psi for a holly based carb.

Yes I have the return line hooked up and the adj FPR. Do you have the pump on a switch or relay?

i been wanting to do a 5.0 swap and the pictures just make it look more and more appealing

[IronFreak]

Wish I could help man but I'm going full MS2 and FI, so I wouldn't have a clue. Best of luck, can't wait to see this thing fire up!

[ballski]

Got the MSD box wired up and it runs.

Only problem is the fuel pump. Has anyone safely ran the stock pump on a carb? My Holley FPR seems to only be knocking the pressure down to about 11 psi. I'm also pretty new at wiring. Does anyone know where I run the fuel pump wire to from the c101 connector?

[hammertime]

Can't wait to see this car run. I'm so glad it got into good hands
