V8 Conversion problem (1 Viewer)

[Townsville]

Gday guys. i've got a 40 with a holden (GM) 253 V8 in it. It goes great but for the 2nd time in 2 weeks i've snapped my fuel pump off its mount. the problem is that when the front springs give, the Dif. comes up and smacks the fuel pump. has anyone else had this problem? and does anyone know what i can do to fix it? electric fuel pump?

Block off plate and an electric pump are probably your only option, I haven't seen any mech fuel pumps specifically meant to tuck closer or anything.

I have not had this problem but looking at the location of your engine appears to be moved very far to the left.

Solution is to either stop the interference (move engine to right, raise engine, limit suspenssion travel) or move the pump/go electric. Only you can decide which are real options but going electric is probably the most straight forward.

like GarageRat and dgangle said use a block off plate and electric pump it's the quickest and easiest fix

You should also look at lowering your bump stops the next thing that will hit is the harmonic balancer and/or the oil pan.

American SBC's fuel pumps are in the frt part of the blk. Yours appears to be in the timing cover.

I doubt that this is a GM engine. The Holden small block V8 was an all Australian designed and manufactured cast-iron 90 degree pushrod OHV engine, manufactured in the capacities of 4.2 L (253 CID), 5.0 L (308 CID), later destroked to 304 CID), and 5.7 L (348 CID - never actually built as a 'production' motor). First introduced in 1969, finally ceasing production in 1999, it powered a variety of Holden vehicles including the Kingswood, Monaro, Torana and Commodore, and proved to be a popular and successful powerplant in Australian motorsport (especially Touring cars). Much of the design is from Ford and one good example is the fuel pump design.

Use a block off plate and then an electric fuel pump to solve the problem you have. Pretty easy.
